Yes, while some of us are forcing deforestation, most are trying prevent further loss by putting reservations. Every hour we are losing forests equivalent to a thousand football fields. Many people are convincing companies to find optional sources.

Deforestation is a major cause of global warming which is causing destruction of no only land habitats but also the ocean. For instance, the raise in temperature is causing coral bleaching which is a habitat to many aquatic species.

The forests are also a source of producing air. People have caused enough air pollution to where many people have to where masks or can get various diseases and cancer. Eventually in the future, if people keep at the rate they are at, at destroying the forests, people will have to buy fresh air or find a different way to create fresh air.
