Question

Which reasons do people give in support of cutting down rain forests?

Answer 1

Answer:

to meet the need for more grazing lands

to fill demand for more lumber

to increase land available for farming

Answer 2

I think c. to increase land available for farming is the correct answer. 

When farmers grow plants, the plants use up the fertility of the land, thus more and more trees and rain forests are cut down to support farmers' needs for land.
