The reading claims that planting genetically modified trees on a large scale promises to bring a number of benefits and it provides three reasons of support. However, the professor states that there are some benefits from these trees but there are serious problems and costs to use genetically modified trees. She refutes each of the author's reasons.

First, the article avers that genetically modified trees are designed to be harder than nature trees and they are more likely to survive than their unmodified counterparts. In contrast, the speaker opposes this point by saying that it is true that genetically modified trees are resistant to weather but they are resistant to particular condition. In fact, she mentions that nature trees are resistant to divers changes such as climate, insects and pesticides. In addition, some of nature trees are killed but sitll the others will survive to any changes, but genetically modified trees are much uniform and if they are exposed to any change, they all die. She adds that if climate changes, they will likely wipe out.

Second, the article postis that genetically modified trees promise to bring a number of economic benefits to the farmers who plant them. On the other hand, the lecturer counters this point by stating that there is hidden cost with these trees. Acutally, the company that modified these trees sells seeds too expensive and after they grow, by law, farmers have to pay that company every time they plant. This appears a contradiction to the information made in the passage.

Third, the passage asserts that the use of modified trees can prevent overexploitation of wild trees to produce wood. Conversely, the professor casts doubt on this point by explaining that modified trees would damage the local ecosystem because these trees often grow aggressively. Besides, these trees would compete with native trees for resourses such as water, soil, and light and even they would be crowded with nature trees and they will affect them negatively. This disputes the third point in the passage.
