What machine do they use to cut down trees in the rain forests?

They use chainsaws to cut down trees in the rain forests. Chainsaws are portable, gasoline-powered saws that use a rotating chain with sharp teeth to cut through wood. They are used to fell trees, limb them, and cut them into smaller pieces for transport. Chainsaws can be dangerous to operate, but they are an efficient tool for cutting down trees in the rain forest.
