Earth Home To 3 Trillion Trees, Half As Many As When Human Civilization Arose
sciencehabit writes: Earth today supports more than 3 trillion trees—eight times as many as we thought a decade ago. But that number is rapidly shrinking, according to a global tree survey released today (abstract). We are losing 15 billion trees a year to toilet paper, timber, farmland expansion, and other human needs. So even though the total count is large, the decline is "a cause for concern," says Tom Spies, a forest ecologist with the U.S. Forest Service in Corvallis, Oregon, who was not involved with the work.
We are losing 15 billion trees a year to toilet paper
Looks like it's time to institute the Three Seashells.
Last I checked, trees earmarked for that purpose were specifically grown for that purpose, and aren't wild trees (thus when they're harvested, they don't count as a lost tree anymore than eating a potato counts as a lost potato.)
Namely, these kinds of farm raised trees:

Those kind of trees are even preferred over wild trees because their growth pattern is much better suited to their end purpose.
But these new numbers are completely right, and actionable. I am inspired with confidence.
...another "humans are killing the plant" story.
And yet another claim to be able to describe the past from proxies or some other Rube Goldberg nonsense. These people have no idea how many trees there were hundreds of thousands of years ago.
Younger trees store far more carbon as they grow rapidly than ancient old growth forests.
That can have a significant effect.

I met a grad student attending Stanford who was part of the Carnegie Airborne Observatory (https://cao.carnegiescience.edu/). She said they flew it over the Central and South America, and her job was counting trees and studying their migrations (if that's the right word). She thought it was a boring subject that few people found interesting, but I was fascinated.
It didn't hurt that she happened to be beautiful.
I'm sorry, but your opinion seems to be wrong.
They think that about 5 billion new trees are planted or sprout annually, yielding a net loss of 10 billion
They don't say where that number came from, most likely pulled from someplace where the Sun doesn't shine. When a section of forest is cleared either by cutting or burning the ground is soon covered in tree sprouts. Take a look at regeneration in Yellowstone National Park after the fires burned about 1/3 of it in the late 80's.
as when civilization arose, but still many more than we need. Good news since I heat my house with wood.
This /. article totally fails to cover the reality that the number of trees has gone up (entire planet covered) and down (almost no trees in ice ages) over the course of the Earth's life. That's how life is.
Oh thank god! We're finally beating back that terrible green goo scenario!

How many trees are we losing due to natural causes?

Bidets (https://en.wikipedia.org/wiki/Bidet) consume very little amount of water (in comparison to flushing a toilet, showering, washing machines, etc) and clean your private parts more efficiently than paper. They are mandatory in many countries, why not in America?
For about a decade, I've envisioned the way to help the poor in countries that get deforested is to replant some of their forests with fruit trees. Even if farmers don't farm, or the country sees unrest, the fruit trees remain. A steady source of food is good in third world countries. Thankfully 'Food For The Poor' saw this too and there is a program for planting fruit trees that I try and endorse to people. If we have a good job, and are on our feet, we should be helping our fellow man, and this is a good way to do that.
God spoke to me
Of the "missing" half of emitted carbon, a bit less than half of that is the net carbon flux dissolved into the oceans. We know that by a really clever bit of mass-balance accounting. We can determine to total CO2 emissions from accurate quantification of the ongoing depletion in atmospheric O2. Dissolving CO2 into the ocean in inorganic form does not change O2. Photosynthesis takes up CO2 and in the process releases back O2, but this takes place on a different slope as combustion of fossil fuel on the plot of atmospheric O2 against CO2. The reason for that is that fossil fuels are largely pure hydrocarbons whereas plant matter -- cellulose, lipids -- incorporates substantial oxygen.
So the biosphere, and someone can correct me on this, it is widely regarded that we are talking about the terrestrial biosphere, is soaking up fully one quarter of the emitted CO2. We are talking mass balance here -- there is nowhere else for it to go.
We're losing it primarily to farmland. There are more trees, more forests today (in North America) then there was in 1900. Take a look, for instance at pictures of NH "wilderness" in the 1930s and today. What was farmland is now "old growth" forest. That story has played itself out all over North America.
Now the opposite is true in other parts of the world - South America, and Indonesia. But it shows that the true culprit is farmland; and as farming techniques become more productive that less is needed.

There is no reason to focus on wood for the paper supply - except the economics of state-imposed rules driving customers to buy solvents. It would be far better and less impactful to use hemp instead of trees for paper, TP and the rest of it. The consequences are huge!

Every day, another 'how horrible human beings are' story. Look, humans are the pinnacle of this planet's long slog towards producing intelligence and of course we're going to modify our environment if we can. Any organism that has the ability to alter its environment does it to make it more habitable. Is this a bad thing? I say no. Do you want us to live in trees? Not reproduce? Keep to a nice, uncomfortable stone age existence? Yup, we cut trees. Yup, there are fewer of them. Big fucking deal. Trees are a renewable resource, and they can replenish themselves quickly. Frankly I think most of the people writing these stories have absolutely nothing useful to do with their time. The planet is changing. Deal with it. Or not, I don't care. Just shut the fuck up.
^ Shame you posted AC, that deserves to have a name put to it...
While you were harsh in your post, your feelings are fair. The "humans are evil" articles are getting old.
"eight times as many as we thought a decade ago"
Yes of course however, they still need to blame humans for something by making up the bull crap stat that there are now half as many as there were before humans arrived. What a load.
So the solution is... to kill all the humans?
Earth is still #1 in trees!
Every day, another 'how horrible I am for killing all my neighbors' story. Look, I'm the pinnacle of this neighborhood's long slog towards producing intelligence and of course I'm going to modify my environment if I can. Any neighbor that has the ability to alter its environment does it to make it less crowded. Is this a bad thing? I say no. Do you want me to live with neighbors? Not murder them in their sleep? Keep to a nice, uncomfortable suburban existence? Yup, I murder neighbors. Yup, there are fewer of them. Big fucking deal. Neighbors are a renewable resource, and they can replenish themselves quickly. Frankly I think most of the people writing these stories have absolutely nothing useful to do with their time. The neighborhood is changing. Deal with it. Or not, I don't care. Just shut the fuck up.
How is it possible to be off by almost an order of magnitude when counting trees? It's not as if the fucking things fly around, is it?
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
As someone who has worked in the printing industry my entire life, I find it insane that it is still illegal to farm hemp. It grows quickly and can produce multiple yields per year. It produces more paper per acre than trees and is a more sustainable resource. It is also a good alternative to the cotton that is used in many specialty papers. Not to mention all of the other uses it has.
Oregon's done a lot since the "plant three for every one you take" rule came into effect; we now have forest fires instead of clear cuts. I am assuming the ecoterrorists like Tre Arrow actually prefer fires.
As we're figuring out, the occasional fire is actually good for the environment. I'd still rather harvest a lot of the trees up here rather than suffer through the fires. Even if the result is simply burning them in a clean power plant(compared to uncontrolled forest fire combustion), that's a lot of green energy right there.
That being said, farmers are idiots a lot of the time because there's lots and lots of monocultures out there. They seem to do mostly fine.

We won't have to do it. If the Ents ever find out that we've been cutting down the Entwives to use for paper to wipe our asses, they'll take care of killing all the humans for us.
...given that it is now believed that the estimate of the number of trees was off by a factor of 8 a decade ago (and we were sure and sure we were sure we were right back then), what makes us think any of these numbers are correct?
page.20: "Originally, much of the United States of America was covered with primeval forest: great areas in the western half and a vast area in the eastern half. In the eastern half, this primitive forest stretched westwards from Maine, around the Great Lakes, to about halfway through Minnesota; ..."
page.21: "It was not until the 1830s, however, that really large-scale lumbering operations commenced, turning lumbering into a major industry of an importance and status equal to that of the railroad and iron industries. ..."
By 1850, as can be seen from Map.1, quite substantial inroads had been made into the virgin timber of the vast forest area in the eastern half

They increased the number of trees by 0.17%.

I blame 70's era hippies. We're not perfect, but there's no objective reason that reshaping the environment to our advantage is wrong. They're just trying to force their preferences on everyone else.
3 Trillion / 15 Billion = 200 years
So unless my math is wrong, according to those numbers we will run out of trees on Earth in 200 years? Somehow I find that hard to believe.
Dropping millions of trees a day could easily get us lots of forests.

Seriously, ffs, upon which wild ass grab do they decide that they have *any* idea on how many trees existed before human civilization?
dunno. I did not read tfa. did you?

maybe see if he's willing to bequeath it to the National Forest Service on the proviso that they classify the area as a Category VI wood? This would mean that the area sees not a single chainsaw with the sole exception of removing dead trees and for public safety (backcutting overhanging growth over roads and tracks, for instance).
