And lowering the human population won't?

No. Population stabilization can be accomplished voluntarily with the
appropriate incentives. Absent mass immigration, we wouldn't be too far
from that now.


No one is *immigrating* into Earth. AIUI, the issue is world P, not US P.

"We" means the US.

The US is not overpopulated by any stretch of imagination.

Not at present, as far as subsistence is concerned, but then our present
population is heavily dependent on fossil fuels for our energy supply.
Replacing all of that energy with renewable sources will be difficult
and very expensive. Things may get very interesting somewhere around
the middle of the century.
