The listening and reading are discussing about influence of the human activities to the survival of birds. In the reading, it states that the influence will be expended, even leading to the birds’ extinct, while the lecturer hold that the evidences mentioned in the passage are not fully correct.
First, the lecturer states that the human behaviors do not cause all kinds of birds lost their habitats. There are still lots of birds and even hawks that can be found in the city. However, it maintain that the expense of human settlements take place of the forest and wetlands that are suitable for birds, which would cause the decline of the birds.
Second, the lecturer said that the growth of the agriculture no longer take more lands than the past, since people already aware of that the bad result of destruction of the nature environment. Instead, more productive crops have been developed and fewer lands are used for agriculture. But the passage disagrees with the decreasing of the agricultural land use.
Third, both materials agree that the pesticides are harmful to the birds. However, the lecturer provides two new choices to protect the crops but not harm to the birds. But the passage claim that the pesticides are not only threatening the birds but also the whole food chain that are based on the pests.
To sum up, the lecturer argued that the evidences in the reading are not convincing which can not prove the decline of the birds any more.
