The suppression of forest fiers Both the reading passage and the lecture are about the results of the decreasing of the amount of forest distraction by fire. The author thinks that the nature system benefits from that. He says that the fire suppression made the trees live longer and improved the health of them. Moreover, the animals that live in the forest are not burned to death anymore. Hence, their population can grow. The lecturer casts doubt on the benefits of the fire suppression. She claims that the forest needs fires from time to time in order to keep his balance. She illustrates it by the lives of the oak trees. The oak trees need a lot of light when they young. The absence of fires prevent them from getting enough light. Therefore the new oak trees cannot replace the old trees. The maple trees are another kind of tree that hurts from the large competition that happen as a result of the absence of forest fires. In addition, the professor says that the increase of the populations of the deer is not so good to the ecological system. For example, the deer eat the new oak trees and not let them grow.
