Answer to Question 1
Game animals are preserved by using hunting quotas; hunting and trapping fees; the monitoring of game populations with adjustments of quotas; excise taxes on hunting, fishing, shooting, and boating equipment; and the establishment of game preserves, parks, and other areas where hunting and fishing are prohibited.
Some problems that have emerged from the adaptations of game species to the humanized environment are: (1) The number of animals killed on roadways now far exceeds the number killed by hunters. (2) Many nuisance animals are thriving in highly urbanized areas, creating various health threats. Opossums, skunks, and deer are attracted to urban areas by opportunities for food, unsecured garbage cans, and pet food. (3) Some game animals have no predators except hunters and tend to reach population densities that push them into suburban habitats, where they cannot be hunted effectively. The white-tailed deer, for example, has become a pest to gardeners and fruit nurseries; it also poses a public health risk because it is often infested with ticks that carry Lyme disease. (4) In recent years, suburbanites have been increasingly attacked by cougars, bears, and alligators as urbanization encroaches on the wild. (5) Coyotes, which once roamed only in the Midwest and western states, are now found in every state and are increasing in numbers. A highly adaptable predator, the coyote will eat almost anything. (6) Suburban parks and lawns, college campuses, and golf courses have become home to exploding flocks of Canada geese.
Answer to Question 2
Pollution is the presence of a substance in the environment that, because of its chemical composition or quantity, prevents the functioning of natural processes and produces undesirable environmental and health effects. A pollutant is any material that causes the pollution. If a substance is nonbiodegradable it means that it resists the attack and breakdown by detritus feeders and decomposers and consequently accumulates in the environment. Finally, the environment is the whole context of human lifethe physical, chemical, and biological setting of where and how people live.
