We should protect our environment by passing laws in nature’s defence
Look after or raise the animals
Don’t kill them
Trang 31Don’t cut down the trees Don’t destroy the forests
Trang 32This does not mean some of the trees cannot be cut. It just means all the trees in one place cannot be cut at one time. It means that you plant new trees when the old ones are cut.
When trees are cut in this way,the land does not erode. The streams do not fill with dirt and the enimals are not destroyed. The industry is beginning to cut trees this way. They are
leaving many dead trees,so small animals will have homes. They are leaving many trees
alone to give shade and shelte for animals. This also means that the forest’s trees are not all the same kind. This seems very important to the survival of the forests
Both the loggers and the forest scientists are trying to agree on things. They have to balance the lumber we need with the forest’s protection. A good rule seem to be not to cut more than you grow each year
What is a change coming in the forest?
What will happen if people plant new trees when they vut the old ones?
Why are they leaving many trees alone?
What are the loggers and the forest scientists trying to agree on?
