11. HOW IS THERE AN
INCREASEMENT OF CO2 ??
AND WHO IS BEHIND
THIS INCREASEMENT ??
12. There are many lines of evidence which
clearly show that the atmospheric CO2
increase is caused by humans.
We know that we inhale O2 and exhale
CO2 whereas trees inhale CO2 and give
out O2. So its our duty to balance
ecosystem. If our population is increasing
then we must plant more trees but
instead we cut more trees for our needs.
So there must be enough trees to
balance the increasing amount of CO2.
