Encouraging people to conserve power would help weaken the greenhouse effect, not increase it. Stopping cutting down the trees in the Amazon forest would also heavily help weaken the greenhouse and not increase it. And unlike the others, using more nuclear power plants wont affect the greenhouse atfect but instead affect our air quality. Our problem is that burning coal, oil, and gas produces carbon dioxide, which adds to the supply already in the atmosphere, increasing the greenhouse effect and thereby increasing the temperature of the Earth so therefore its D.
Well, depending on how long the migration is, many of the animals (mainly birds) could get sick and die, lowering the population. They could be shot by hunters, lowering the population.
