The reading and the lecture are both about the benefits and effects of the planting of genetically modified trees. Where the author of the reading states that plantation of this kind of tree is more beneficial, the lecturer suggests that there are some serious problems and cost effects related to genetically modified trees. The lecturer casts doubt on the main points made in the reading by providing three reasons.
First of all, according to the reading genetically modified trees are more resistant to certain natural calamities. However, the lecturer refutes this point. She says that these trees might be effective in resisting one type of natural disaster but it can not sustain the natural disasters as a whole. Furthermore, she mentions that the unmodified counterpart of the modified trees can withstand long term disasters like global warming or a sudden disaster like a pest infestation. If most of the trees are wiped out, then also some members would survive.
Secondly, the reading states that genetically modified trees are more economically efficient as they can grow at a faster rate, and also, can yield more amount of food crops than unmodified trees. Nevertheless, the lecturer disputes this argument by stating that farming with this kind of trees often put an extra burden on the farmers as the company's which sell the seeds of these trees charge more to the farmers. Moreover, the farmers can't use the seeds harvested from the full-grown trees next year, as there are some laws state that the farmers have to pay a surplus to the same company in order to sew those seeds next year.
Finally, the reading claims that using this kind of tree will help to save endangered tree species which people generally cut down for timber and burning woods. On the other hand, the lecturer believes that genetically modified trees sometimes grow without any bounds, and most of the time they are planted among the wild trees. As a result, these trees threaten the population of the wild trees and out-compete them by harvesting an enormous amount of nutrients from the soil.
In conclusion, although the reading and lecture are both about the benefits and effects of farming with genetically modified trees, the three main points made in the passage are effectively challenged by the lecturer.
The
