Now, listen to part of a lecture on the topic you just read about.

Unfortunately, the suggestions you read about are unlikely to work in this case. First of all, using toxic and traps would cause some unintended harm. You see, these traps do not differentiate between the yellow, crazy ants and other native species of ants. That means that the native ants can be harmed by the traps the island near Australia you read about does not have any native ants. So no unintended harm was done there. But in the palm forest on the Seychelles islands, there are native ant species present that we want to protect. And these ants would certainly be killed by the toxic traps.

Second, cutting down broad lived trees might not solve the problem. You see yellow crazy ants can thrive in several different kinds of ha BI ta TS. Yes, they thrive in a habitat with broad lived trees. However, they also do well in ha BI ta TS like open areas with increased sunlight. The trouble is, if we cut down the broad leaves trees, we would create areas of increased sunlight inside the palm forest. So in other words, if we cut down broad le AV ed trees, we might destroy 1 type of habitat that the ants like, but we'll be creating a new habitat that is also very friendly to the yellow crazy ants. So we won't get rid of the ants that way.

Finally limiting human activity around the forest might slow down the end spread a little, but it might lead to a serious economic problem.

You see, the islands palm forest is the regions main tourist attraction, and the unique trees and animals that live in the palm forest attract not just tourists, but also scientists who conduct studies on the regions, rare species. In fact, tourism and visits from scientists are the most important sources of income for the local people. Therefore, trying to limit human presence around the forest would negatively affect the economy of the whole region. Summarize the points made in the lecture, being sure to explain how they cast doubt on the specific solutions proposed in the reading passage.
