In the United States, it had been common practice since the late 1960s not to suppress natural forest fires. The “let it burn” policy assumed that forest fires 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.
The reading passage discusses three kinds of damage that are cited by critics of the "let it burn' policy. However, the speaker in the lecture casts doubt on the claims made in the article. She mentions that the forest fires are part of an ecological cycle and they are fundamentally good.
First of all, the author holds that Yellowstone fire scorched almost one third of the land and destroyed most of the vegetation. In contrast, the lecturer brings up the fact that smaller plants were able to grow in the areas cleared by the fire. These plants needed open unshaded fields and could not survive while the forest was inhabited by giant trees. In addition, the fire generated high level of heat that helped certain seeds to germinate. Therefore, the species in the forest were more diverse after the fire, according to the lecture.
Secondly, the writer contends that the flames negatively affected wildlife in the park causing big animals to flee, such as deers and elks. Moreover, the smaller ones were not capable of escaping. Furthermore, the destruction of the habitat and disruption of food chains made it impossible for surviving animals to return. Nevertheless, the lecturer points out that the growth of smaller plants allowed a population of rabbits to occupy the forest again attracting predators and other species.
Finally, the excerpt posits that the fire hurt the local economy cutting short the tourism season. Conversely, the lecturer indicates that what occurred in 1988 was a rare incident due to a unique combination of factors like low rainfall, unusually strong winds and accumulation of dry undergrowth and this does not take place every year. As a result, the lecturer avers that visitors and tourists came back to the park.
