7.5x more than scientists thought
lol
Let’s penalize North Africa, Saudi Arabia and India for not growing enough trees.

Let’s not pretend that desert expansion is a result of human activity.
Yet they boldly proclaim “...the total number of trees has plummeted by roughly 46 percent since the start of human civilization, the study estimates.”
We could establish goals of x trees per square mile and send them a democrat for every square mile that doesn’t meet the goal.
A truly renewable fuel source.
Ever since the first Surveyor satellite was launched in 1968, the land area under tree cover in the world has measurably increased every year.
How large does a tree have to be to count?
This is the other part of the global climate debate that no one talks about in politics:
Land Use. The impact of agriculture vs. forests on CO2 levels.
Perhaps this is more of a culprit, for CO2 rise, than American SUVs?
Who knows?
But then again, CO2 is not a greenhouse gas, (methane and water vapor are), so why are we talking about land use, unless we talk about its impact on methane and water vapor?
People want to eat,and it’s hard to farm in a forest.
3 trillion trees take up a LOT of earth-warming CO2.
We may be heading toward another ice age!
:O!
There are 7.5 times as many trees as previously thought, but....
There are half as many trees as there were before people.
First - poor estimates strain the credibility of the estimates.
Second - most of the deforestation of Africa occurred in early human history. The implication that humans are responsible also strains the credibility of the estimates.
Dropped 46%, and yet recent studies in South America have revealed that most of the “Rain Forest” there post-dates the various MesoAmerican cultures i.e. a lot of Central and South America was deforested by the MayIncAztecs and *grew back*.
So right there I have to doubt their numbers. They’re probably also counting the desertification of the Sahara which roughly correlates to the appearance of protohominids, which they have “deemed” the start of “human” civilization.
Save the trees - eliminate ‘rat cities.
US forest acreage hit its low in 1920 (750 million acres in 1920, out of 1045 million (not incl. Alaska & Hawaii) when Europeans arrived).
Since then we’ve been replacing forest (currently at a rate of about 3 million acres a year).
One reason is that we don’t need farmland to grow food for the horses who were the main transpostation power before cars.
In 1910, 25 to 30% of all the farmland in US was used to grow food for the horses.
Oil/gas has a FAR smaller footprint than growing food for horses — 83 million acres for horse food in 1910, compared to 16 million acres for all energy production and conversion now.
But we’d be going backwards with solar and wind, which have a big footprint.
Tree Leaves Matter !!!
The culprit is the growth of ‘rat headcount.
