The reading passage contends that suppression of forest fire have a positive impact on the forest and many creatures there. On the other hand, the lecturer gives several points that contradict this argument.
First of all, the lecturer argues that fire in forests affects positively on the lives of trees. To be specific, in the case of oak trees, there are some places where many, densed old oak trees prevent young trees from growing due to the lack of lights. Also, other species of tree also cannot get enough resources to grow in such a place which has densed population of trees. This casts doubt on the reading, in which trees can live longer and healthier by the suppression of forest fire.
Also, according to the lecturer, the ground of the forest benefit from fire. Because huge trees, which grew enough already, prevent the access of sun light to the ground, ground suffer if there is no refresh by firing. In addition, many scientists recently proved that more nutrients will come from burned trees and plants, and it makes the ground much healthier afterward. This rebuffs the reading passage's argument that suppression of forest fire enable the ground to become healthy and abundant with many nutrients.
Finally, the lecturer points out that forest fire can increase the population of deer. This is because deers like to eat leaves of oak trees, and from the positive effect of fire on the oak trees, we can imagine that forest fire make deer abundant with their favorite food. This rebutes the reading passage's assertion that wildlife including deer and forest animals benefit from the prevention of forest fire. |
