I believe that killing big hundreds-of-years-old trees
removes sun protection from smaller trees;
and that sunburn makes smaller trees vulnerable. Dead big trees leave lots of dead roots
that need fungus to recycle them.
The natural fungus gets to be predominant.
Fungus tends to optimises its environmentm
as do all living things
except people.
Conditions evolve, then, that favour fungus....
Eventually the fungus is more active than it should be;
and trees die inappropriately, from "dieback".
Thieves steal the remaining trees by clear felling;
and the forests never grow the same
until after a few more ice ages
Trees bring water to the surface
that otherwise would stay deep below
or perhaps go out to the oceans Destroying trees and ground cover overheats the Earth
more than any other form of global warming Planting trees has to be done with food in mind --
healthy farms can be just as good as trees or better.
