Forests used to act as cabon sinks and a state of approximate
equilibrium was maintained. Deforestation contributes to global
warming in a couple ways.

Im sure you meant "carbon" dioxide sinks and I agree. Every
green plant sucks up CO/2 and gives off O/2. And yes trees are
cut down,, but all logging companies replant. They arent going to cut
their own throats by not replanting.



MOST logging companies in the US and Canada reforest.. this is not the case
in S. and Central American countries where the forests are being harvested
and replaced with cities.
