Essay (summary)

In the lecture, the professor made a few points about the effects of forest fires. The professor argues that forest fires can be good for forest. However he talks differently from the lecture, the lecture says negative things about the forest fires, but he does good things.
The first point the professor makes is that if there are too much trees, is hard for tree to get sunshine, or the light. Also, in some way, there are not enough space for trees to grow, trees are holding the land, so they can hold the land even though it is windy, but if trees are not grown enough, they can't really do anything, which is going to cause trouble someday. In this case, teacher talks good thing of forest fires.
Another point was that burning a forest actually puts more nutrients into the land. The lecture does not say this. It says that fires take nutrients out of the soil. However, the teacher says there are more nutrients at the top for plants to use.
The professor tries to make the point of good things forest fires because everyone thinks the fires in negative ways.
