In the United States, it had been common practice since the late 1960s no to suppress natural forest fires. The “let it burn” policy assumed that forest fire would burn themselves out quickly, without causing much damage. However, in the summer of 1988, forest fires in Yellowstone, the most famous national park in the country, burned for more than two months and spread over a huge area, encompassing more than 800,000 acres. Because of the large scale of the damage, many people called for replacing the “let it burn” policy with a policy of extinguishing forest fires as soon as they appeared. Three kinds of damage caused by the “let it burn” policy were emphasized by critics of the policy.
First, Yellowstone fires caused tremendous damage to the park’s trees and other vegetation. When the fires finally died out, nearly one third of Yellowstone’s land had been scorched. Trees were charred and blackened from flames and smoke. Smaller plants were entirely incinerated. What had been a national treasure now seemed like a devastated wasteland.
Second, the park wildlife was affected as well. Large animals like deer and elk were seen fleeing the fire. Many smaller species were probably unable to escape. There was also concern that the destruction of habitats and the disruption of food chains would make it impossible for the animals that survived the fire to return.
Third, the fires compromised the value of the park as a tourist attraction, which in turn had negative consequences for the local economy. With several thousand acres of the park engulfed in flames, the tourist season was cut short, and a large number of visitors decided to stay away. Of course, local businesses that depended on park visitors suffered as a result.
Both the reading and listening materials discuss the "let it burn" policy. The reading, to be more specific, claims that this policy has caused several damages. On the contrary, the professor holds a different idea and states that the policy also brought about multiple advantages after the fire.
The reading begins by stating that the fires destroyed various trees in the park along with other sorts of vegetation. This is challenged by the lecturer, who feels strong that the fires have created a good opportunity for many plants species to thrive. He further explains that the scorched land created more space for other species and some seeds need to be exposed to the great heat provided by fires to develop.
The reading then points out that the wildlife in the park was also affected.The professor, in contrast, asserts that the fires did not interfere with the food chain or the destruction of habitats. He supports his idea by discussing the ideal habitats created for many species such as rabbits and heirs after the fires, and those animals become the targets for predators; hence maintaining the quality of the food chains.
The reading finishes by arguing that the policy to let fires burn had negative toll on the local economy. The lecturer refutes this, claiming that the burning did not happen regularly, in fact it has not happened in Yellowstones ever since 1988. Indeed, the visitors soon came back to Yellowstones to enjoy its scenery; thus it did not cut down on the tourist season nor the number of annual vistors.
