In the lecture, the professor says that the argument in the reading is far from convincing . The reading argues that the constant growth of human population ,the increased production in agriculture and the pesticide used in the farm have affected the animals in America, especially the birds, the number of which has decreased , and this trend will continue. The speaker’s disagree with those points. Her reasoning is in the following passage.
In the first place, the lecturer states that the numbers of
some types of bird increased while the numbers of some other types decreased and the universal conclusion that all birds species are affected negatively can not be reached.His point of view is different from the
first point in the passage that birds are suffer from the lack of habitat because of the human. It is true that some bird
decreased in number. But there are also increasing number of complaints about more birds in urban area . Some birds are frequently being found on the streets and other places in urban area. Some species of bird shrank , while other species enlarged.
In the second place, the professor argues that the development of agriculture
is not destructive for birds, which contradicts with the second point in the reading that points out that growing agriculture results in the decline of birds population. The professor says that the developments of agriculture is based on
crops that can produce more food
but do not need more land for production. So she reach the conclusion that agriculture growth did not harm the birds population.
In the third place, the woman points out that the pesticide will not affect birds negatively in the future. This is also in contrary with the third reason in the material that use of pesticide
will increase and
bring harm to the birds species. In the speech, the woman says that pesticides in the future will be different
from the traditional pesticide . There are two reasons , first ,new type of pesticide that is less toxic id being developed. Second, there is the trend to develop pest-resistant crops, which is genetically resistant to the pest without the use of pesticide. So the professor reaches the conclusion that pesticide won’t do as much harm current pesticide do in the future.
