Global Deforestation Demoed In Google Earth
eldavojohn writes "On Google's official blog, they claim a 'new technology prototype that enables online, global-scale observation and measurement of changes in the earth's forests.' Ars has more details on what Google unveiled at Copenhagen. If you have Google Earth installed, you can find a demonstration here. Many organizations and government agencies are on board with this initiative to put deforestation before the eyes of the public. If only satellite data of North America existed before the logging industry swept in!" It's interesting to contemplate the implications for intelligence gathering of Google's automated tools to compare satellite photos.
Interestingly, before the white man appeared in North America, there were an average of 8 trees per acre and now there are an average of 220 trees per acre in the US alone.
Just saying...
Beer is proof that God loves us and wants us to be happy.
The original poster wishes he could see North America before the logging industry swept in. Around 30-50 years ago, his intuition would have been rewarded. But, for the last decades, much of the United States has actually been reforested, rather than deforested. The reasons for this are complex and mixed, but some factors include the original mills going out of business in the Northeastern USA, adoption of better forestry practices, a reversion of farmland to homesites - which invariably means planting even more trees, and so on.
Indeed, Americans have been catching something of a break as they have planted so many trees that North America would be a net carbon sink, if they didn't also drive so many cars. This picture changes as all the new trees mature and their carbon uptake decreases. But, the important lesson here is that while Americans might be bad about CO2 emissions, they have, in their own way, also showed how areas can be reforested, that were once barren.
This is my sig.
We have more trees here in Oregon now than were here 100 years ago or even 200 years ago. (Unlike nature, we don't let forest fires burn them down.)
We plant them all over the place and take care of them. Every time we cut one tree down, we plant 3 to 10 more of them.
We really are not deforested to the west of the Mississippi. Now east of the Mississippi is a different story. But no one is talking about deforestation on the east coast. They only talk about it out west where we have plenty of trees to go around.
School kids went out 30 years ago on filed trips here in Oregon to plant trees. Why? As a reminder that most of the income in this state came from logging, and that timber was a renewable resource. If we plant trees today, then in 20 years when you are old enough to work a timber job, there will be plenty of trees to cut down.
I live in a county that has been devastated by the loss of 80% of the logging industry. We have as many trees now as we had 30 years ago. The only difference is we have 15% unemployment and we can't cut and replant trees to actually make a living.
Earth first -- we will log the rest of the planets later

Not from a satellites, but there are some maps. For example: http://www.esd.ornl.gov/projects/qen/nercNORTHAMERICA.html
Note the complete lack of forests over most of NA about 15,000 years ago.

Not much forest under the ocean bits.
The world is made by those who show up for the job.
Depending on your timeframe.
Forests covered about half the land before settlement, now about a third.
But the amount of forests have been going up in the last decade. One reason is because most of the forests belong to the evil logging industry, and they have an economic incentive to expand forestation if they want to expand their businesses. Today we have about as much forest as we did 100 years ago.
The advent of the automobile and other forms of transport, plus better farming techniques, also helped spread the forests, since we don't need so much land dedicated to feeding us and our livestock.
Demolished or demonstrated? Maybe some Googelian combination of the two?
fwarren: I believe fighting natural forest fires has proven to be policy error. For a citation please see the burning of Custer State Park. There are no more Smokey the Bear commercials because forest fires are actually necessary to prevent catastrophic fires. From what I remember reading, the 40+ years of Smokey the Bear campaigning, and fire fighting left MILLIONS of tons of fuel in the form of old dead timber.
I guess I'm just trying to point out that while some of Oregon's other forestry programs might be a benefit, fighting forest fires for decades can and has lead to a catastrophe.

We must think BIG and GLOBAL like GOOGLE! We will launch saplings into orbit on vast arks and scattershot them into the ground, thusly reforesting the world! Mwa ha ha! We call it the Forest Continuity Project and pay for it with lumber credits and carbon back bearer bonds and the illegal unicorn horn trade out of Romania! Yes, most of the trees will shatter on impact and fail to achieve a planted state, but if just one tree saves just one child then $50 trillion is worth it! Follow me, boys, into the glorious future and let the trees rain down o'er me!
Just as long as people keep in mind that satellite photos don't always tell the whole story. A team of Canadian scientists went north recently in an ice breaker. Satellite imagery indicted that the pack ice had expanded rather than contracted, which was totally at odds with Global Warming models.
What they found when they actually got to the location where the satellites indicated the pack ice started, it wasn't there. It had retreated more than a hundred miles beyond where it was thought to be. The satellite cameras had been looking at a slurry of rotted ice fragments that were so broken up the ship just blasted through them at full speed without even noticing it.
Basically, the reality on the ground was very different from what appeared to be happening on cameras located a few miles overhead.
I've calculated my velocity with such exquisite precision that I have no idea where I am.
Lots of fast-growing trees suck up more CO2 than ancient forests.
But they are the forest industry, so they must be evil.
Seriously, we want to slow down deforestation? Stop using trees for paper products. The US needs to get over their high and mighty "We can't use hemp because its taboo" crap.
I was going to reply with a highly sarcastic rebuttal, but closer inspection shows that you may be right.
Wikipedia reckons hemp grows at 'up to' 25 tonnes/hectare/year of dry above ground matter. This gives 'up to' 13 tonnes/hectare/year for fancy 'high yield' hybrid poplar, intended for papermaking.
There is a huge amount of wiggle room with those figures, 'up to' is often meaningless (I'm going to give you 'up to' 100 billion dollars) and both sources are doubtless from organisations trying to promote their different 'crops'. Also theres the problem of how much actual paper you get from a tonne of almost-unspecified plant material respectively for each crop, and the required fertiliser and labour inputs etc etc.
I would also wich to point out that despite my name on here I'm usually very skeptical of "HEMP: The Wonder Plant!" type suggestions (even though I do approve of one particular use of certain varieties, at least).
This is a substitute for a clever sig that fits within the maximum number of characters.
That's the crux of the matter, *employment*. This is hardly ever addressed when it comes to draconian "no you must stop this" laws and proposals as regards the vast rural areas of the world.
This is what I see all the time: Wealthy urbanites in the industrialized areas are all for "conservation" in areas they don't live, but they have pitiful to non existent whacko theories on what exactly the human beings who live in those other areas are supposed to do for a living. Can't cut down jungle hardwoods for lumber=evil, stop. Can't cut down the big trees to make row crop farms=evil. Can't cut down and replace trees with other species that have a globally useful economic function=evil. Can't raise stock animals because they emit methane greenhouse gas. Can't do row crops en masse because it requires spraying and artificial; irrigation, uses too much water. And so on, a HUGE list that wealthy urbanites have on the "you shouldn't do this" side.. Can't do anything at all on your property because one month out of the year there is a mud puddle that supports the breeding of the endangered three eyed flying newt-owl. all sorts of laws like that too, even if it means you are now instantly unemployed with not much in the way of immediate alternatives..yet the bills still come in every month, plus property taxes.
So, that's nice and all for all the well meaning urbanites, but a couple billion people around the planet are supposed to then live on "eco tourism"? For real, I see that thrown out by some of those folks as some sort of credible option. Nuts... Funny,speaking of nuts, I am not seeing any huge move for urbanites to exist entirely on a diet of imported wild harvested tropical exotic hardwoods nuts and berries either, which is the only other crop you can get from wild forest. But then, whoops, you are stealing the food that the animals need to eat too....so that's out...
That's about what is left if you can't harvest the trees and use them in manufactured articles and for construction lumber, or make some cropland. And forget mining anything, all of that is just instantly evil no matter what...
You just can't have it both ways, if these people want to just wall off huge forest areas of the planet and let them go wild forever, completely naturally, with no human use, they must first come up with viable, realistic and constructive alternatives for useful modern employment in areas that are currently at the bottom of the economic foodchain. Or offer a couple billion people a direct cash perpetual welfare subsidy to do nothing and just live there. Anything else is unfair, unrealistic, and practically speaking, unworkable.
Basically, I am for sustainable use, including managed forests, and I am *way* in favor of getting rid of the backward "environmental" laws that forbid use and harvest of all the fifty buzillion acres of dead forest land they let burn up for no reason every year in the western USA, said dead forest expanding rapidly from such things as the pine beetle. That's a huge waste, and contributes mightily to air pollution when it burns up from uncontrolled wildfires every year, with zero economic or practical benefit for anyone really. We could be using that wasted wood for vast biochar manufacturing facilities and for replacements for coal in some electricity plants for example, providing much needed jobs in rural areas, going to more sustainable energy sources, and also improving soil tilth with the biochar in established row crop lands. But no....can't do that, wouldn't be environmental, have to let it just burn up "naturally", while the runoff silts over all the creeks and wipes out the fish and stuff...
How about this proposal to solve all the environmental problems at one whack..it would work, too.. let all the big cities burn up "naturally", I mean fires break out there all the time, so just stop putting them out, which would greatly help to reduce the planet's population (those folks all want that as well, "too many people!"), most of humanity lives in big ci
Extremely large swaths of land have been turned back to forests because they are no longer needed to grow crops to feed us and our livestock.
Urbanization is only about three percent of the US area, while farmland is a lot more, yet continually shrinking.
There are multiple factors, http://www.nationalatlas.gov/articles/biology/a_forest.html
"The forest cover in the U.S. has actually increased in the last 100 years - mostly due to farm abandonment in the East and fire suppression in the West."
