what is the biggest ecological problem facing the earth?

Answer 1

global warming and the consequences: loosing of habitats for many species, ocean temperatures raising, and so on. Watch the inconvenient truth. There is the answer.

Answer 2

There is a species called "Homo Sapiens Sapiens" that is wrecking most of the planet in amazing ways. They are an ecological disaster of amazing proportions. Specifically, though, I would have to say that the biggest problem caused by the monkeyboys is their use of non-renewable energy. They chop down trees, clear land and dig for oil. Then they dump the afterproducts into streams, rivers, the oceans - and never mind the smell. Have you ever tried to bathe a human? Until this past century, most of them thought that baths were a health hazard (seriously ... dude ... gross).

Answer 3

right now it is global warming as CO2 injected into the atmosphere causes a warming of the atmosphere and the earth's surface. The warming causes more water to be evaporated into the atmosphere. Since water vapor itself acts as a greenhouse gas, this causes still more warming; the warming causes more water vapor to be evaporated, and so forth until a new dynamic equilibrium concentration of water vapor is reached at a slight increase in humidity and with a much larger greenhouse effect than that due to CO2 alone.This feedback effect can only be reversed slowly as CO2 has a long average atmospheric lifetime.
