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 of chemical 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.
Both of the passage and the lecture discuss about the relationship between bird populations and the development of agriculture. The passage states that the continuous increase in agriculture will lead to decline in bird populations. However, the lecture casts doubt on the statement in the passage.
First of all, the passage claims that the expansion of human populations and settlements continue, birds' natural habitats will continue to disappear. Yet the lecture counters the passage by mentioning the expansion of human settlements actually provides larger habitat for birds. Since a lot of people who live in the city have complained about the increase in bird population in the city.
Secondly, the passage mentions that to keep pace with the growing population, the agricultural activities must increase as well. Nevertheless, the contends that tough human populations increase in United States, there are less lands being used in agriculture. This is because people now start planting more productive crops, so they can still produce same or more amount of food with less land in use.
Finally, the passage argues that as human settlements expand and agriculture increases, the use of chemical pesticides will also increase, which are harmful for birds. Notwithstanding, the lecture refutes the passage by arguing people have been aware of the harmful effects that pesticides brought to birds. As a result, new and harmless pesticides have been developed, as well as more pests resistant crops, which can effectively reduce the use of pesticides.
