In the past century, the steady growth of the human population and the corresponding increase in agriculture and pesticide use have caused much harm to wildlife in the United States,birds in particular. Unfortunately for birds, these trends are likely to continue, with the result that the number of birds in the United States will necessarily decline.
First, as human populations and settlements continue to expand, birds' natural habitats will continue to disappear. Forests, wetlands, and grasslands will give way to ever more homes, malls, and offices. As the traditional areas suitable for birds keep decreasing, so will the size of the bird populations that depend on those vanishing habitats.
Second, agricultural activities must increase to keep pace with the growing human population. The growth of agriculture will also result in the further destruction of bird habitats as more and more wilderness areas are converted to agricultural use. As a result, bird populations in rural areas will continue to decline.
Third, as human settlements expand and agriculture increases, the use ofchemical pesticides will also increase. Pesticides are poisons designed to kill agricultural and home garden pests, such as insects, but inevitably, pesticides get into the water and into the food chain for birds where they can harm birds. Birds that eat the poisoned insects or drink contaminated water can die as a result, and even if pesticides do not kill birds outright, they can prevent them from reproducing successfully. So pesticides have significantly contributed to declines in bird population, and because there will continue to be a need to control agricultural pests in the future, this decline will continue.
The reading passage discusses some trends adopted in the United States that are negatively affecting wildlife, especially birds whom their populations are declining due to agriculture and the use of pesticides. However, the speaker in the lecture casts doubt on the claims made in the article. She mentions that the arguments in the reading are unconvincing.
First and foremost, the author believes that the human real estate development is destroying natural habitat for birds and leading to a decrease in their numbers. Nevertheless, the lecturer brings up the fact that although some types of birds are dwindling in numbers, other kinds are actually growing even more in the urban areas. For instance, some people complain about the overgrowth of seagulls and pigeons in cities. In addition, the populations of predators that feed on those species, such as hawks and falcons, are also increasing as well.
Secondly, the writer holds that bird species in rural areas are declining because of the exploitation of lands for agriculture to match the rising human population. In contrast, the lecturer challenges this point of view. She illustrates that the introduction of more productive varieties of crops is helping farmers to depend on smaller areas of land to get the same yields, hence saving bird habitats in wilderness areas.
Lastly, the excerpt contends that the drop in the bird population could be partly contributed to pesticides which leak into water or are present in insect bodies, which birds consume. Consequently, large number of birds die due to the toxicity of pesticides in their food and water. Conversely, the lecturer asserts that even though this is happening now, we cannot project that this process will continue into the future. This is mainly due to the fact that less toxic pesticides are being introduced. Moreover, crops that are genetically designed to be pest-resistant do not need pesticides.
