Due to deforestation, we are losing our forests. There are quite a few ways to help stop deforestation. Letting family and friends know about deforestation and what it is and what causes it is a way to help stop deforestation. Avoiding biofuels, biomass etc as they release gas emissions contributing to the climate change problem. Reducing your use of one use products is also another good way to reduce deforestation as mass use of one use products can harm nature.
In the US there are laws for example endangered species act, lacey act, wilderness act, and the roadless rule. Which prevents illegal products from entering.
