Environmental Science and Population Essay

sing the textbooks, the University Library, or other resources, answer each of the following questions in 100 to 200 words.

1. What would you include in a brief summary on the history of the modern environmental movement, from the 1960s to the present? There were many notable events during this time period. The very first environmentally sound act was the Air Pollution Control Act of 1955. The act declared that air pollution was harmful to public health as lung carcinoma became more prevalent within communities. Strict Government regulations and pollution requirements became the norm for other facets of the Environment as well. www.epa.gov/air requirements. The Federal water pollution control act followed in 1965 gave the Government limited controls to federal water pollutants due to limited enforcement authorities and money.

This act was finally solidified in 1970 revision with an imposed clean water act without exceptions. www.water.epa.gov. My own personal favorite involves the marine conservation law of the seas. Developed by the Environmental Protection and Biodiversity Conservation Act of 1999, the act was designed to protect and manage threatened migratory and marine species: Including Wales, Dolphins, Porpoises and threatened Fauna. www.environment.gov.au/marine species.

2. Explain the primary concern over exponential population growth. What promotes exponential population growth? What constrains exponential population growth? Exponential Population growth is the main concern that the earth would not have enough resources to supply its inhabitants. There are two basic principles involved, the idea of exponential growth and its ultimate control. Believing that with the over population of people the earth becomes over used and the resources are depleted, which in turn affects the quality of the planet directly and indirectly.

Modern medicine, health care and education has allowed people to live longer lives now than ever before, with knowledge and contraceptive devices people have more control over the population birth growth. Unlike China and other countries that still limit how many children a family may be allowed to reproduce in order to keep the population growth rate lower. www.nature.com/exponential/logistics.

3. Explain the primary concern over exponential population growth. What promotes exponential population growth? What constrains exponential population growth?

4. What is carrying capacity? Compare predictions for human population growth in developed countries versus developing countries. What will occur if carrying capacity is exceeded?

5. How do individual choices affect natural ecosystem? Provide examples from your personal or community experience.

9. What is carrying capacity? Compare predictions for human population growth in developed countries versus developing countries. What will occur if carrying capacity is exceeded? A Carrying capacity is determined by how much the earth can sustain the population with its current resources. The largest factors involved is the ability to obtain education and wealth. The competition is tough for food and water. It is critical that the carrying capacity be controlled or the natural resources will be depleted. If this happens the human race will not thrive. www.science.howstuffworks.com.

10. How do individual choices affect natural ecosystem? Provide examples from your personal or community experience. There are many way how we affect our eco system; smoking, polluting the air in our lungs and the environment of others, riding a bike other than driving a car to limit pollutant emissions, wasteful water usage, washing the car or watering the lawn. My own example is that I don’t recycle plastic, paper, or glass. Plus, I am lax when leaving rooms with lights on.
