Is Agriculture Sucking Fresh Water Dry?
sciencehabit writes "The average American uses enough water each year to fill an Olympic-sized swimming pool, and global agriculture consumes a whopping 92% of all fresh water used annually. Those are the conclusions of the most comprehensive analysis to date of global water use, which also finds that one-fifth of humankind's water consumption flows across international borders as 'virtual water' — the water needed to produce a commodity, such as meat or electronics, if the ultimate consumers were to make it themselves rather than outsource its growth or manufacture."
Do we actually need all those agriculture products?
Isn't there a different way to use water for the same purpose with possibly higher efficiency?

if the ultimate consumers were to make it themselves rather than outsource its growth or manufacture.
There are some good solutions in The Humanure Handbook. That does not change corporate agriculture, but a little awareness on our behaviour is a good thing.
As Mark Boyle (The Moneyless Man) once said: if we knew how hard it was to purify our drinking water, we sure as hell wouldn't shit in it.
Nae king! Nae laird! Nae yurrupiean pressedent! We willna be fooled again!
Do those figures take into account the watering in my mouth? I don't think so.
Because that would explain why they're so fat.

It's important that all resources on this planet are reduced to a commodity studied as traded between businesses and consumed by consumers, especially essentials such as water. Only then can we go the laughable way of England and have a completely privatised water supply, costing much more in real terms than it ever did when run by government on behalf of the people. And how about carbon dioxide emissions? You know what would be better than investing in nuclear and other alternatives to fossil fuel? A licence to pollute more! Some entrepreneur could make a mint selling or brokering these licences. We could call them... carbon credits.
The great thing about the old religions was that they were miles away from pretending to be based on reason. What was illogical was ascribed to the mystery of God. The free market is more insidious, being an exercise in logic based on unsound premises.
The French don't get through that much in total.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Now can we set up a pretend entity to buy and sell our pretend water, much as we buy and sell pretend money now? It takes the emphasis off of what's happening with our real water, much in the way the national reserve has allowed us to ignore what dire straights we're in concerning our real wealth.
I'd encourage anyone interested (and worried) by these issues to look up and study everything they can find about Permaculture. Solutions are available, if we use our brains.
Australians are dealing with it as well. The cities are drinking up more and more water. In the east where they have lots of water there is no question of starving the farms to feed the cities. But in the west water is a limited quantity.
Sure, we could kill the bread basket of the US... or in california's case it's fruit-basket. But to what end? We're already importing a lot of food from mexico because the farms have been starved for decades. Huge stretches of California that used to be covered in farms are now dust. It has nothing to do with land management. The land is fine... there is no water. And there used to be lots. The cities drank it.
Now, the cities need it... and if I have to choose between the cities getting the water or the farms then I'll choose the cities. But it's a dangerous game and the best solution is to build more dams, more reservoirs, more pipe lines, and more water treatment centers. All of that costs money but the cities have NOT built water infrastructure to keep pace with their consumption. The farms use a lot of water but their consumption has gone DOWN. The consumption of the cities has gone up and they haven't built anything. They just grow and grow without building new infrastructure for water. Even the big cities in the east aren't keeping pace. New York City has some giant water pipes under it that pump water out of an aquifer under the city. When initially built, the city only needed one of those pipes. The rest was extra for growth or if they wanted to shut down one for a time. Now they can't shut down any of them and are piping water in from farther away. But they've built nothing to deal with it.
Contrary to what many environmentalists are saying, sustainable growth doesn't mean "no growth" instead it means expanding our infrastructure as we grow so that we don't have shortages. Killing the farms to get water to the cities only shifts problems. Do that and all our food will say "product of mexico" or canada or some other place because we won't grow anything. The Australians are having the same problem. Huge amounts of water flow into the sea untapped in eastern Australia. Dams that were scheduled to be built 30 or 40 years ago were never built. It would apparently spoil the view or something. So farmers in Australia are literally committing suicide because their family farms are being starved of water and driving them out of business. To say nothing of the fact that the country is increasingly dependent on foreign importation of food when previously they were largely self sufficient.
Point being... Do not starve the farms. If the cities need water then stop looking at who to take it from. Man up and build more supply. There is plenty of water flowing out into the ocean that is never touched to say nothing of rainwater that is never touched. Furthermore, cities could much more readily make use of gray water for cleaning/etc then the farms. Starve the farms and you'll be sorry... it will just mean food prices start doubling and you lose all control over food quality standards because its all imported.
I've decided to stop wasting my time responding to AC trolls/sockpuppets... so if you want a response from me... login.
It's too bad that once water is consumed it disappears forever.
Oh wait, no it doesn't.
The criminal activity today is to privatize water.
Fuck these Agenda 21 fascists
Fuck the slashdot experts (who don't know shit)
The perception is that when something is cheap, it is of low value so it doesn't matter if you consume too much of it.
If you look at areas where water is scarce and where wars are fought over it, or where it has to be desalinated i,e, it's expensive, you'll find the users are a lot more careful over how much is used and how it is used.

Desalination .. just have solar powered desalination plants so that desalinated sea water can be piped inland to the farms .. israel does it .. if you dont wanna be stuck with a salt mound .. just remix the salt with the agricultural outflow and it'll be dumped back in the sea.
That is fit for the 21st century. We had a food revolution in the 20th century, where we used massive amounts of fertilizer and massive amounts of water, this resulted in massive amounts of food. But at what cost? We chopped down most of the great rainforests and are quickly depleting what remains of the prime topsoil left in the world. We need a paradigm shift. We have the technology to make maximum use of water, we only need to make the investments needed to reap the savings. There are numerous small scale initiatives around the world, utilizing mangroves, saltwater irrigation, greenhouses, hydroponics. Wastage results in more than 1/3 of food going bad or being thrown away due to market conditions. Much work needs to be done if we are to feed 10 billion humans.

Why don't we use Antarctic Ice? It should be transportable in large quantities. A super oil tanker sized ship should be able to supply some i guess.
But would it be financially realistic?
Maybe using lots of water in agriculture is actually a good thing.
Lets actually look at what side effects might be if plants weren't getting enough water, for a start photosynthesis needs lots of water for the electron exchange of the reaction, now yes there are alternatives (arsenite) usually they are toxic, also only work in specific bacteria designed to do it that way.
Fundamentally, the more water the more photosynthesis, the more sugar (for us and livestock to eat) and oxygen we get. Therefore maximizing water usage for agriculture without drowning the plants is a good thing for all of us. It's not like water doesn't fall from the sky, it is the most abundant substance on this planet and not using it in one area does not suddenly help get it in desert areas where there is droughts and famines.
I need to know how many Libraries of Congress each American consumes. For global agriculture I guess we could use Libraries of Alexandria...
I have something in common with Stephen Hawking...
With the passing of time, local crops have dwindled due to inter regional trade, and supply demand constraints. For example, in arid regions of India, instead of wheat "Jowar, Bajra, Ragi...." etc., were grown which use much less water. but since majority eat wheat, in the interest of business, farmers shifted to Wheat, which uses more water. In other regions, which never grew rice(due to lack of water), canals saw increase in rice production, and movement of local populace to wheat and rice, instead of the local cereals which consume less water.
So everybody does not need to eat rice. Rice and wheat users can have other cereals added to their diets, and increase demand, and some cultivation area can be reclaimed, and balance restored.
Another aspect is hybrids. Many high yield varieties(which in the long run are not all that more beneficial) often require higher water content. In irrigated regions, people often switch to those varieties. In the short run you have better profits, but since these are not as resistant to local conditions(in some cases), it also means increased pesticide expense.
So with intelligent Farming, and growing crops actually suited to the region, water usage can be minimized.
Apart from that, there is the irrigation question. Using drip irrigation drops water usage by over 60-70%. We have used it on an piece of land where irrigated water was a scarcity, and illegal mining killed local rivulets and creeks. Due to very less quantity of ground water, and only perennial source being an artesian well, we had two options, stop growing, or use wisely. thanks to some govt subsidies and support, we were able to setup a drip irrigation system, which resulted in low water usage, and now we have surplus water.
Unfortunately, much of agriculture, even in developed world, does not move to this kind of savings unless there is a sword hanging on the head. Countries like Israel have water shortage, so they have moved to intelligent use. If other places where shortage is not there yet, also move, it will result in water saving.
Lastly, in many areas, rain water is not stored effectively, and a lot goes waste(flows into the sea). If a large part of that can be channeled to groundwater using recharge zones, it will replenish groundwater which can actually help people survive a year or 2 of dry season.
That said, other than conservation, many places can also have strict policies to block untreated industrial waste flowing into rivers, which will result in higher fresh water availability

This study borders on sleight-of-hand to my mind. At least the way it is presented is misleading.
The headline says that 92% of freshwater use is in agriculture. What it doesn't mention is that the vast majority of that "use" of water is rain that happens to fall on farmland. We could increase that number by converting land use to arable land without changing any natural flow of water. For instance, the city of Adelaide is about the same area as the county of Cornwall and is built largely on prime agricultural land. Moving the city 100 miles North East onto unfarmable land and resuming agriculture there would noticeably increase the agricultural use of water - but it would actually be an environmentally good thing.
When it comes to diverting the natural course of water (extraction from rivers, building dams, draining lakes etc - what you might call exploiting the natural resource), the use of water in agriculture is much less - the majority here supplies water for urban residences and industry.

Because water sprayed on plants and on the ground dissipates into space! And we have angered the sky gods so they are not sprinkling new water upon us as much!
The author of the article needs a bit more education in earth science. Yes I know the problem with pesticide and fertilizer contamination is real but if areas do proper watershed management it's just fine. What is the REAL problem is when you get idiots in a dry area wanting to pipe water out of a different watershed to them. For example, all the morons living in California wanting great lakes water. and large dams that reduce the flow to create recreational lakes for rich people.
Plus for example Arizona, Nevada, and California has a population greater than it's natural resources can handle, so people need to start moving away or live with the lack of water. Disrupting a watershed in that way will only cause problems for the area having the water taken out. It's there because of a balance of the water consumed is equal to the water collected from rain over the watershed area.
I'd support Pumping the water from the end of the Mississippi to California, but they don't want that water, they want that clean stuff we have up here, not the 1100 miles of turd dumping that happens starting in Chicago. Which brings up another point, rivers flowing to the oceans uses 80X more water than agriculture and industry combined. Why are we not talking how rivers are sucking fresh water dry?

Agriculture does not consume water it uses water. Virtually all the water is returned to the eco system after use.
However there are different sources of water. Ground water versus surface water. Depletion of ground water is not sustainable as water table levels are dropping. Surface water use is sustainable but also has consequences as stream dry up as they are diverted or become filled with water so contaminated it can't be re-used down stream.
Some drink at the fountain of knowledge. Others just gargle.
Part of the problem is the traditional large subsidy that agricultural water gets (both via the infrastructure costs and in direct pricing). Farming would make better use of water if it had to pay the price.
PS: "Olympic-size swimming pools per year" is a strange way to measure water usage. "about 6.8 cubic metres per day" is a much clearer way to express this number. In particular, this makes it clear that low-flow toilets have a negligible effect on water use compared to dishwashing, showers, etc.
We're polluting fresh water at a frightening pace. This fracking obsession is threatening to perminately destroy the ground water supply for a third of the country. Ironically agricultural waste is one of the largest sources of pollution. Fruits and vegetables can be grown more efficiently but we are also grain obsessed in this country and grains are harder to reduce water consumption. We are also obsessed with meat and it uses vast amounts of water in production and processing. Some times our own laws shoot us in the foot. I was interested in gray water irrigation as in using waste tap and shower water for watering lawns and vegetable gardens. Would you believe in most areas it isn't legal? I'm talking about filtering it and rendering it safe first but there aren't standards for it in most areas rendering it illegal. If those that could went to composting toilets and gray water watering systems you'd only waste a small percentage of the water and you'd avoid using any tap water for plants and yards. Lawns are often the largest domestic water use especially in the southwest. Every house could water their lawns with gray water but instead the government forces you to dump all that into the sewers which in many areas lead right back to the ocean.
FYI to all those touting desalination. Picture watering your lawn with gasoline and taking showers in it because that's roughly what the water costs. The joke is the cheapest solution to any resource problem is conservation but people want solutions that allow them to keep wasting.
It really puts grain dumping at sea to keep the commodities prices high into perspective.
My ism, it's full of beliefs.
>>Do we actually need all those agriculture products?
>Yes, we do.
What if we reduced our meat consumption, and reduced consumption of other water-hungry foods?
You are of course very correct about being more efficient about water use, as proved by many people in many desert and semi-desert areas.
Some coal seam gas wells must evacuate water from the great artesian basin for years before they can have anywhere near productive gas yields. Around the Injune area, I've seen these mind-bogglingly huge evaporation ponds - actually trying to transfer precious groundwater back into the sky
And although I've heard Santos are trying hard to make their reverse-osmosis plants work (that would be trying to pump water out of the aquifers at the gas extraction wells, and then back in somewhere I assume has no gas yield potential), they're having big problems making it work properly at scale.
I wish I had some better links, but it's of serious concern:
Almost 300 billion litres of water extracted with the gas annually. I've never heard what price Santos, Origin, QGC etc. are paying for this water: are they in fact paying any at all? And, "Millions of tonnes" of waste salt to be dumped somewhere.
I know the situation in Queensland. And I know how much influence the Queensland greens have on the state labor government there. The only conclusion I can draw is that the Greens are just as corrupt as the rest of them.

It was never done to save the consumer money, it was done to save the GOVERNMENT money. Whatever politicians say, they don't really care how much the average citizen has to cough up for public services. They simply care that they can spend less on them so they have more money to waste on pointless wars so they can be best buddies with the USA (yeah, right) or subsidising undeserving "asylum" seekers and their 10 kids.
My comment is not so much about agriculture usage but about what happens when we "use" water. Is that the water goes down the drain and into the sewage system. From there it is treated and released to be used again and again. Look at almost any city on a river, they draw the water out of the river, use it for everything treat it and back it goes into the river. So if you live down stream of a water user, more than likely you are drinking some water that has been run through a sewage treatment plant. Unless the user is on the coast where when done with the sewage treatment it is dumped into the ocean. If more of the larger cities that are on a coast pumped the treated water inland???
Passionately Indifferent
In a few years I will retire, my wife ask frequently where do you want to live?
My reply, anywhere you want in the USA, except the western states that do not border on the Pacific ocean or the Mississippi river. Industrial agriculture not population density is the problem. So, Money or People? Money wins for more industrial agriculture and less people.
A decade ago we should have started the great irrigation canal from the Great Lakes or Hudson Bay for those west-central states, but now folks should just move east or west out of the disaster area (to little as opposed to to much). If the project were private industry it would just carry oil.
Industrial agriculture will feed the world, export food around the world, increase USA food prices, and food-stamp welfare will be an unacceptable burden on the national debt. Maybe we will have a USA national famine of plenty in 50 years.
Unaccountable leaders are masters, and unrepresented people are slaves. How do US and EU fare?
Massive amounts of water; massive amounts of fertilizer; massive amounts of herbicide; massive amounts of pesticide. The dirt is mainly there to keep the stalks upright.
...did I mention the massive amounts of subsidies and massive amounts of corporate ownership?
Another problem that could be solved if we started an emergency nuclear power plant building program, on the scale of the mobilization for WW2
plenty of electricity available for desalinization.
Water used to make a product that's shipped isn't at all necessarily water that's shipped. If the water is consumed in place but not included in the product it's not shipped. So claims that "virtual water flows across borders" is BS.
Likewise water that's used along its natural flow path, and cleaned (enough) to return it to its original destination, is impacting only in the place where it's diverted. When we put a factory on a plot of land we disrupt that land, and we're willing to accept some deletion from nature. Nature is very resilient, and not all diversions and conversions of it have unacceptable consequences.
We do go too far, and we do waste far too much. But exaggerations like these don't do anything except discredit the already difficult efforts to require management of what we use.

What is so alarming about using 92% of all the water that is used in agriculture? If we cut agricultural water use in half, it would still account for 84% of all the water that is used?
100% percent of all the fresh water that is used is not 100% of all available fresh water. Some places have too much water, others too little, the primary issue is the distribution of the water, then the protection of it from harmful pollutants - the great thing about water is that it is about 100% reusable.
Ken
i'm surprised you got modded up for a bald claim with no substantiation.
let me turn your claim around a little and see if you still agree. for it
to be true that we "need" all the ag products currently produced, it
would also have to be true that,
- there are no replacements that are not ag products,
- we are using the ag products we've got with 100% efficiency,
- we don't eat too much anyway.
surely, that's not what you're saying!
I would have been worried if 92% of our fresh water consumption was being used to wash our cars or water are lawns. It seem to me that having the vast majority of our water consumption being used to grow food is a good thing.
"The average American uses enough water each year to fill an Olympic-sized swimming pool"
There is no freaking way I use this much water in a year. On the average I use no more than 300 cubic feet per month, that would be 3600 cubic feet per year. An Olympic size swimming pool holds 88,286.66721 cubic feet of water, so I call bull shit.
"I bow to no man" - Riddick
What? Like, from the toilet??
The average American uses enough water each year to fill an Olympic-sized swimming pool
That really doesn't seem that much for a whole year. A person can't live more than 4 or 5 days without water, and health professionals recommend people drink 2-3 liters of water per day. And that's just drinking water - people also need to bath and use water for cooking.
global agriculture consumes a whopping 92% of all fresh water used annually.
Something seems wrong for that figure. It sounds like they're saying 92% of water is diverted for irrigation, but to get that figure you would at least have to be counting all the rain that falls on all vegetation that is eventually harvested in some way.
as 'virtual water'
Wha..? Yea, I don't need to RTFA - this is obvious bullshit pushing some agenda to put all the water resources under the control of a few unelected tyrants. Screw that.

If you are interested in more information about the connection between good choices and the environment here are some short articles:
Current industrial agriculture practices are not sustainable for many reasons, irrigation being a significant one. It depletes water and soil quality. There are alternatives. Do a search on Sepp Holzer, Bill Mollison, Geoff Lawton, and hugelkulture for a start.
Save money on your utility bills, buy a gadget and help the environment at the same time. Install low flow shower heads. You get a similar perception of "thrust", but with less water. These things can save you a lot on your water bill. Heating water is another large portion of utility expenses and taxes the environment ( ie nasty things are burned to heat the water ). Wash your clothes in cold water when you can.
You vegans are worse than the religious and atheist zealots.
Also, I seriously doubt that the net liquid cost of 1kg of cow is 15,500 L. Think about the water cycle carefully for 60 seconds (specifically, think about where cow urine and milk goes.)
...shouldn't talk about a world they don't understand. The modern farmer is not a hick chewing on a stalk of wheat and wasting natural resources. Farmers manage their resources, including their water & soil. They are using drip irrigation & water reclamation to produce more food more efficiently than ever before. They are also using soil analysis, GPS location and yield results to optimize crop rotation and soil amendment application. Can it get better? Of course. Does the rest of the world need to catch up with the leaders in the field? Absolutely. But don't for a minute believe that agribusiness isn't just as high-tech as every other industry in the world.
Oh, and for the hippies telling me to stop eating beef and that I should live on homegrown lentils, twigs and leaves: fuck-off - I'm an omnivore - I'll eat anything that doesn't eat me first.

Most farmers do everything they can to get rain water to run off the fields so they don't flood and over-water the crops. Then they pump water out of the ground and apply it to the fields as needed. The rain water then dumps very quickly into the rivers and causes flooding down stream. A simple way to take care of this is to dig a large basin (1-2 percent the area of the fields and say 20-30 feet deep) to collect the rain water, then pump that back onto the fields as needed and only when it's dry would they need to pump water from the deep aquifer. It would help all of the problems, but would cost a bit to set up. Oh, and this would re-apply the fertilizer that washes away when it rains - which is another problem both down-stream and as a cost to farmers and a natural resource issue (phosphorous).
All those problems come down to poor resource management.
After a record-breaking 6-1/2 FEET of rain in 2011, water is more than plentiful in the Cleveland area. Please take some. Actually, take a lot. We're drowning over here!
Nothing to see here. Just another dominant social theme: water scarcity. I guess they already have a solution for that, but it requires more global governance.
This is really funny. He presents a lot of data but you call him worse than religious and atheist zealots. Your only argument, on the other side, is that you somehow doubt that the data posted is true. It's incredible how people can be so blind and emotional when it comes to defend their lifestyle.
Virtual water is a nasty little beast -- pumping it takes fuel (trucks, trains ships) -- making fuel takes water. Go read The Big Thirst -- it's interesting.
We'll never change our water habits until water becomes sufficiently expensive.
The obvious solution and what's best for the environment is to eliminate agriculture. If we eliminate agriculture that will reduce consumption by eliminating consumers. By eliminating consumers the amount of harmful byproducts like CO2 from automobiles, power plants, and breathing can also be reduced. And without consumers the world will be a much more sustainable and ecologically balanced place. It's the only socially, morally, and ethically responsible solution.
In the article "Comparison of Water Consumption between. Greenhouse and Outdoor Cultivation"
http://www.itc.nl/library/papers_2006/msc/wrem/mpusia.pdf
we can see that greenhouses save some 50% of water compared to outdoor cultivation (on page 11).
That mean we can 'readily' half the agricultural water consumption. Imagine greenhouses the size of Nebraska...
I have an idea about how we can treat our planet better.
Instead of wasting all our fresh water on crops that we eventually burn in our vehicles, how about we burn that black oily substance that comes from decayed creatures? It certainly isn't doing the planet any good lying deep under rocks.
All vehicles that can run on 100% petroleum-based fuels should be given a special sticker to show others how environmentally-conscience the owner is.
Any and all shortages and other problems, like contamination, are due to allowing economists instead of engineers manage water distribution.
One simple way to use less water in agriculture is to employ hydroponics. These systems can use up to 90% less water than traditional farming. Another point is that the development of better (cheaper/more efficient led lighting) is beginning to tip the balance in terms of economics since produce can now be grown indoors 24/7.

The notation that water is flowing across international borders is sure to be a harbinger of UN panels, treaties and other power grabs.
A 20-30 foot deep pool comprising 2% of arable land would be prohibitively expensive. In areas with a high water table, you'll have to keep it from caving in; also you are going to need to blast rock in many parts of the country, and the pool is going to have to be lined with something expensive (either concrete or a thick plastic liner). You'll also need to dredge that thing on a regular basis, as ag runoff is rather silt-laden.
Theoretically possible? Sure.
But "an easy way to help"? Nope.

Archer Daniel Midland was founded as a linseed-crushing business. Linseed oil and most of the seed industry's other products were used by the paint industry.
Then the paint industry figured out how to make their products from petroleum, and ADM became obsolete.
Around the same time, agribusiness was experimenting with thyroid poisons, to make their animals fatter with less feed. These were carcinogenic to the animals, and to the people who ate them too. But they found that corn and soybeans served essentially the same purpose, and that's how the meat industry switched to seeds. This is according to one of Ray Peat's articles...

The average family of 4 uses about 1/3 of an acre-foot of water per year. That's roughly 100k gallons, for a family of 4, or 25k gallons per person. An "olympic-sized" swimming pool is roughly 600k gallons, which is 24 times what an "average person" uses in a year.
I live in the west where water usage is metered and highly regulated. NOBODY uses anywhere CLOSE to 600k gallons a year for personal consumption. When you start off a summary with a wildly inaccurate statistic like that it makes it really hard to take anything that follows seriously.
Body's are buried air tight container so our body's are not allowed to give back what is has taken over the years. By my guess that might be a Glaser or 2 of water buried.
Jack of all trades,master of none
You vegans are worse than the religious and atheist zealots.
Also, I seriously doubt that the net liquid cost of 1kg of cow is 15,500 L. Think about the water cycle carefully for 60 seconds (specifically, think about where cow urine and milk goes.)
It's vegan logic at it's finest. Same sort of crap that they use to tell people that if their piss is yellow, they're not drinking their necessary 2 gallons of water a day. These are the same morons wwho will measure their piss to find out that they're excreting 95%+ of the water they take in, and then reach the conclusion that they need to drink 3 gallons of water a day to prevent dehydration.
We. Are. At. Peak. Water! C'mon, people, at the rate we're consuming water there will be none left for future generations. Won't someone please think of the children?
Do what you can, with what you have, where you are.
actually trying to transfer precious groundwater back into the sky
If only there were some natural mechanism by which precious water might fall from the sky back to earth! But then the sandworms would die, and as we all know, the spice must flow!
Socialism: a lie told by totalitarians and believed by fools.
This is so absurdly inefficient, it's disgraceful that we even came up with the idea ... and even more disgraceful that we're subsidizing it and placing tariffs on imported ethanol (which is typically made from more efficient things, like sugar cane).
Hopefully the idiots we have in congress will realize this and not be bribed into renewing the subsidies later this year.
The figures aren't talking about rainfall, they're talking about irrigation and industrial and household use.
Where does it say that something has to waste water to be organic?
There is no reason I can't feed my plants with a dripline, in a greenhouse and recover a lot of my water and still not use proscribed chemicals or pesticiedes.
Some greenhouses use predatory insects (spiders) instead of pesticides.
hurr
They seem to have this idea that water is actually used up, not recycled. You can see it in things like people whining about the "virtual water" that coffee requires. They moan about the massive amount of water that goes in to growing the coffee for one cup. One cup of "actual" water, gallons of "virtual" water.
Of course they seem to forget that all coffee has to be grown in an area of the world known as the coffee belt and is normally grown in areas called rain forests. That "rain" part is not for show, it rains 300+ days a year in those places.
I guess they think the coffee beans suck the water up and it vanishes for good.
Can't we get Superman to bring as a few icebergs or a bit of Lake Vostok?
Yay, I can substitute protein with a giant pile of carbs. That's JUST what Americans need...
Support more choices in goverment-Vote 3rd party.
So if I build a vertical greenhouse with soilless gardening techniques, provide the allowed nutrients in my drip irrigation from decomposed seaweed and other organic sources, am I still organic?
Using NEW controlled environment agriculture methods I can grow 100 times the product per square foot as a traditional farm or even a "modern agriculture" farm, my crops are always in season 365 days a year and I use no industrial chemicals in production.
Are you still going to bang the drum that Organic means intentionally flawed and inefficient farming?
No thanks. I'd much rather eat free-range animals. They fertilize the soil and "farm" the soil without inputs or fuel. That's far better than using fossil fuels and fertilizers to produce and harvest grains. I do my part by limiting my consumption of factory/industrial food.
Be relentless!
Do questions make shitty headlines?
If you have a disagreement with the post's claims, make your argument. If you find the language unclear, ask for clarification. If you think there are unreasonable insinuations being made, call them out. That's what I intend to do with your post.
To me, the above complaint doesn't look like a rational problem with the argument: it looks like an ideological problem with where you think it's coming from. Perhaps you think all academics are out-of-touch elites whose expertise should therefore be disregarded. Perhaps you think poli-sci students are liberty-hating "liberals" (according to the warped American definition of the word). If so, foolish caricaturing and stereotyping only looks good if you're preaching to the choir. It has no bearing on the validity of either argument.
Maybe I'm wrong. I hope so. I'm just sick of reasoned debate being jettisoned for ideological reasons of tribal identity and taste.
I think you posted a reply meant for someone else in response to my comment about Meatless Monday and reducing water.
It is from Wikipedia, which to my knowledge isn't a vegan organization.
You can buy a low sugar cereal in just about any supermarket. Cows milk isn't high carb. You can also got non-sweetened soy or almond milk. You can buy whole grain bread for your lunch, peanut butter without sugar and you can buy 100% fruit jelly The carbs in pasta are extremely low glycemic If all of that wasn't true, you could still pick many other easy meals for a Meatless Monday
I don't things happen like that in the real world anymore. There may be a few boutique livestock farms that operate like that and sell meat few people can afford. Most meat comes from animals kept in factory farms whose waste is just dumped ( can't be used for fertilizer because of the toxins in the feed ). Lastly, it takes about 11 pounds of wheat to produce one pound of beef. Similar ratios exist for other meats and other palatable to humans plant products. If you are interested in saving fossil fuels and fertilizer, the easy choice is to eat your wheat/plants directly ( whole grain pasta, whole grain bread, cereal, etc ) instead of filtering it through a cow where you have to use...........and grow, and use resources for 11 times more.
Wikipedia copied it from somewhere else that either practices or believes that vegan logic.
