Many of the people living on this planet realize that most of the sources of air and energy we receive from are usually by Trees. Trees are the most important besides the growth of grass because most of the oxygen is build from the earths atomsphere after Trees are being produced each year. The leaves alone can be use to develop sources of food; like fruit after consuming stronger pigmints once it receives water.
The worse thing anyone can do to a tree is cut them down and build Cabins out of them or start a fire which burn a park or forest down and causing an increase of dramatic temperture. The saddess thing about this issue is that many animals live inside Trees and can end up being homeless with no place to stay during the winter due to the lack of sources they need from their environment to survive, this major problem alone can make animals who live in trees not to exist.
People should find newer methods each year to protect these Trees from the abuse of people who do not care much of the environment they live in or not have any concern for the animals living there and once they do it will save us alot of trouble from losing mpre oxygen on this planet.
