The reading and listening materials have a conflict of opinions about genetic modification. The writer believes that it is beneficial to the society, which is contradicted by the following lecture.

　　Firstly, the writer claims that genetically modified trees are more likely to survive/ have a better chance of survival since it is hardier than unmodified ones. However, the speaker casts doubt on this opinion by saying that natural trees tend to be genetically diverse, so there will always be some resistant kinds that get to survive when (they are) exposed to an environmental challenge. Genetically modified trees, on the other hand, are uniform in genes, which means they would all die if (they are) faced with a challenge that they are not designed for.

　　Secondly, the author argues that genetically modified trees are more profitable to farmers, while the lecture views this issue from an opposite angle. According her, the seeds of modified trees cost a lot and by law, farmers have to pay the company every time they grow. So there won’t be much financial gain for the farmers.

　　bring more economic benefits is more economically competitive generate more profits is more profitable

　　Thirdly, the passage states that genetically modified trees make it no longer necessary to overexploit wild trees. By contrast, in accordance with the professor, this claim does not hold water. It is because modified trees tend to grow more aggressively and would outcompete native trees for natural resources like sunlight, water and soil nutrition. As a result, modified trees would actually wipe out the native trees planted around them.
