This is beginning to be alleviated. For thousands of years, humans have
supported their agricultural habit by using their own excrement for
fertilizer along with that of their cows and horses and pigs. This practice
ended early in this century with the Progressives pushing through the FDA
acts which made such use of human waste illegal. Since that time, the
topsoil in this country has steadily declined.
However, in Texas and a few other places, this is beginning to be reversed.
Biosolids (class B types, not the toxic class C) from New York City ("NEW
YORK CITY?" the Texans decry....) are being shipped to a few towns in Texas
and being spread over the land. The land is fully capable of handling as
much agriculture as we want if we put back our wastes.... This is not being
done, instead it is being drained into the oceans.

And this is a good thing.

No one here advocates purposely destroying species, but if one cannot
compete, then it must either be altered or replaced. maybe an endangered
species' niche is no longer needed (like many North American predators), or
it cannot live by more than a fragile existence. If we are to support the
laws of nature, of which evolution and survival of the fittest are the
paramount ones, then we must not make undue efforts to sustain species which
cannot survive on their own. In this we are extending our own failed welfare
policies to the natural kingdom.

Its also about improvement. If a species cannot cut it, then it either needs
to be improved or allowed to die out if it cannot, to be replaced with
another than can compete.
