The points held by the lecturer respectively go against the viewpoints claimed by the reading material.
First, urbanilization (urbanization) does do harm for some types of the birds (brids) , but in total facilitates other types and increasing population of birds in the city area. Seagols (seagulls) and pigeons are more often seen in the urban because they can have more food, and hawks can be more often seen in the city than in the past. Therefore, it is not accurate the (用that 会不会更好?应该从句吧!)expansion of human settlements will unavoidably cause the decreasing the size of the bird populations.
Second, it is true agricultural will result in diminishing wilderness areas, but the prediction in the reading material is opposed by the lecturer. She mentions that in America, with the development of technology, less and less land have ( has, 原文中是is) been occupied to be the agricultural land year by year. Crops are sufficient for people and there is no need to destruct the wilderness area to convert to agricultural use. (姐姐总结的好精炼!)
Third, the lecturer points two aspects to object the projection in the reading material. The lecurer (lecture) admits that the traditional pesticides do harm the birds. However, the trend about (of ) the future pesticides will not have the issue(issue还有,只是less toxic). Firstly, Less (小写less)pesticide will be used in the future. Secondly, the pesticide used in the future cause the crops be (to be)more unattractive to the insects, which will have no harm to the birds at all.
感觉很多细节没有提到,而直接用模糊词汇替代了~ 下次提高精确度吧!
