Answer the following questions in at least 100 words. The answers are found in Ch. 1–4 of Environmental Science.
1. What would you include in a brief summary on the history of the environmental movement?
The environmental movement is closely related with the appearance of environmental awareness. Before 1960, very few people knew the term ecology. Environmental concerns were absent in the political and social spheres. However, a groundbreaking book by Rachel Carson, Silent Spring, was published in 1960 and large numbers of people became aware of the consequences of humans’ encroachment upon the nature in terms of the use of highly toxic chemicals like the DDT. Again in this period, various environmental events like oil spills, news about the possible extinction of several species have also helped create an awareness of the issue (Botkin & Keller, 2011, Ch. 1). People were divided into two camps: environmentalists (those having dismal views that life on earth is in peril) and anti- environmentalists (those opposing the environmentalists and saying science and progress are necessary for humans). Today we have overcome this either-or dichotomy and understood that science and progress do not need to be poised against the environment. Environment can be protected while industrialization and progress are maintained. Clean energy, new environmental regulations, and energy-efficiency are belied to help humans protect the nature.
2. Explain the main point concerning exponential growth and whether it is good or bad. Compare exponential growth to a logistic growth curve and explain how these might apply to human population growth. What promotes exponential growth? What constrains population growth?
Exponential growth is occurs when a population increases by a fixed percentage every year. Exponential growth is encouraged in the nature when a species is...
