Yes, and that fungus is what keeps that system alive in most cases.
The transference of nutrients back and forth, plant to plant in a
symbiotic relationship with eachother. When we do anything to disturb
that fungus, we are literally killing the forests. When lakes are full
of poisons, which were not needed in the first place, become part of
the forest, the fungus are killed, and the system is lost. Correct me
if I am wrong.

Yes, but in nature, when say, a forest burns down, other plants come in
or are germinated, creating another type of system. Other animals
migrate to that system, forage and graze on what is now available,
until something happens again, in nature, which will cycle back to the
original plants and animals...the cycle of life goes on. I am not
talking now, about the forests which are being slashed and burned for
agriculture now. I am just talking about the natural order of what
occurs on virgin soils as the sample. Regardless whether the fertility
is low for agriculture, it is fully sustainable to the forests original
structure. It is those forests which are rapidly disappearing before
they can even be studied effectively. Am I off base here?

Yes, with this I fully agree. Sadly.

I fully intend to go to University this fall for environmental
sciences. I have a need to know more about this. I am bitten by the
bug of knowledge. I only have one regret, that I did not do this much
earlier in life. I suppose 41 is not an old age, but I sure do wish I
was already in the science mix...It will take me 5 years to get my PhD,
but I intend to go for it.
If I am incorrect in any of the above thinking, please tell me. I am
open and willing to learn.
