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.
The reading states that the development of human's population will likely decrease the bird's population until disappear and provides three reasons of support. However, the professor explains that the statement in the reading is not truth and refutes each of the author's claims.
First, the article claims that human growth will expand greatly. Consequently, the population of birds will be destroyed. Because humans have transformed the bird's natural environment in malls and office, the birds’ home is forced to decrease. The professor refutes this point by saying that urban development has increased some population of birds. While some birds have decreased in number, others have been enhanced by human growth. She states that now more and better habits allow birds such as falcons and hawks to populate more in residential areas.
Second, the article posits that the growth of agriculture also triggers the decrease of bird's population. Thus, the bird's population will be minimized. However, the professor says that in the USA less and less land have to be used because the introduction of the variety of crops. This means that more food can be produced for a unit, so there is no need of increase agriculture.
Third, the reading says that it will be an addition of chemical pesticides as a result of increasing agriculture. So, these chemicals can reach animals' food and water harming them. The professor opposes this point by explaining the use of two techniques will avoid future problems with birds. First, the pesticides will be made less toxic. Second, the introduction of pest crops resistant, which reduce the use of regular pesticides, yet it won't harm the environment.
