We can use less paper so that the amount of cutting the trees will decrease.
We can reuse the paper.
We can use both sides of the paper.
We can use less furniture that made by wood so that less trees wil be cutted down.
Or we can plant more trees.
We should reduce the use of paper, and recycle them to lower the amount of lumbering.
Imposing laws to control the area which is allowed to lumber can also help improving the situation.
