what are the impacts on environment due to increasing farmland areas?

Answer 1

Well, in order to make room for farmland, they cut down tree's, mostly in the rainforest and sometimes on wetlands, which are also becoming scarce. They use a lot of chemicals and pesticides on the crops that messe things up since they run off the land into the water. That really hurts the ecosystem then. There is an overgrowth of plants in the water, they block the sunlight, then the underwater plants die, then the fish who eat them die because they run out of food, then the bigger fish die...etc. It's all a chain reaction. Increasing the farmland area's kills the environment.

Answer 2

More people get food - aren't people more important?
