Summary
The concern that a large amount of trees are being cut down is being discussed . As I recently learned that is not the only problem we have with trees and the amount of oxygen produce . The recently measured the tree growth and learned that it is seven percent shorter today than it was in the 1800's . The reason for this is the amount of ozone pollution in the atmosphere . As the amount of pollution increases the height of trees decreases .
Opinion
This is a very serious matter . Just as people are concerned on the amount of trees being cut down they should be concerned about this . This creates many problems for humans . The problem that i am most concerned with is the amount of oxygen that will be available . We humans are only creating problems for ourselves .
