Ch9 – Population & the Environment 1. Neo-Malthusian argue that population growth is detrimental to the environment, esp. when it is accompanied by affluence (so that a birth in India, eg, is going to do far less environment harm over that child’s lifetime than will a birth in the U.S.) 2. Barry Commoner’s perspective is that many variables other than population are critical elements in environmental deterioration, & the use or abuse of technology plays an esp. significant role in environmental degradation. 3. Julian Simon’s view of population growth is hardly harmful; in fact it can be good because it provides more brains, increases the ability of humanity to innovate, & create markets for goods & services. 4. The impact of early civilizations on the environment was great or minimal? 5. Humans have utilized fire for at least half a million yrs. 6. The collapse of numerous ancient agricultural systems has been traced to ecological imbalances. Eg: North Africa, Near East & Mesopotamia. 7. Explorer Juan Cabrillo visited C.A in 1542; he could see the mountain peaks in the distance but not their bases while he anchored in San Pedro Bay. A thermal inversion in the area trapped the smoke from Amerindian fires, bringing about air pollution as well as human health hazards. 8. Early civilizations needed to avoid water pollution in order to ensure safe drinking water in the urban areas. This prompted the development of wells and water storage tanks. The Aztecs under King Ahuitzotl brought in spring water through a stone pipeline. 9. The problem of environmental degradation can be broken down into several key factors: pollution, crowding & violence, global warming & ozone depletion, deforestation, decreasing ecological diversity, & overgrazing. When waste increases to the point that it can no longer be accommodated by the ecosystem, it becomes pollution. 10. Pollution’s primary forms are biological or chemical. Human population density often leads to increased biological pollution. Today, the crowding of large numbers of people into small places has brought about increased pollution almost everywhere. One case of chemical poisoning in Minamata Bay, Japan, where industrial waste containing mercury was dumped into the fishing waters. Local fishermen continued to eat their catch; the result was several thousand cases of a debilitating disease now referred to as Minamata disease, a form of mercury poisoning. 11. The urban atmosphere often contains high counts of microorganisms; gases, such as carbon monoxide & oxides of nitrogen; & a variety of other chemical compounds, including sulfur dioxide. The United States Office of Technology Assessment estimated that the effects of air pollution may cause 50,000 premature deaths in the U.S each year—about 2% of annual mortality.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
