The biggest impact on the Amazon rain forest is the activities of humans. Growing population needs the space and the trees are cut down because people need jobs and the wood can make a lot of money for lumbering companies. Unfortunately, even the people who depend on the rain forest are among the ones contributing to its decline.
WE cut things down and kill things. We destroy the habitat of the animals and take away their food supply. But we can also try to conserve by replanting trees and plants and set hunting laws. We can also not kill animals.
We also improve the rainforest by enforcing laws against hunting endangered species. Together, we can save the rainforest!
