Question 36 Current estimates suggest that to halt increase in levels of greenhouse gases in the atmosphere, we would have to reduce emissions by what percentage? A. 80-90% B. 10-20% C. 60-70% D. 5-10% Question 37 How does carbon dioxide contribute to global warming? A. It is less dense, leaving less space in the atmosphere for oxygen. B. It absorbs heat from the sun, preventing it from escaping into space. C. It is created during combustion, which is an exothermic process that collectively heats up the earth. D. Carbon dioxide does not contribute to global warming. Question 38 The release of CFCs into the atmosphere may lead to several hundred thousand new cases of skin cancer each year and destroy many valuable food crops. Also, ocean plankton—on which the entire ocean’s food chain depends—may be severely damaged. This is referred to as __________. A. resource depletion B. ozone depletion C. environment depletion D. contamination continuance Question 39 What is the term for the cost an individual or company must pay out of their own pocket for an economic activity? A. private cost B. social cost C. economic cost D. associated cost Question 40 What is a good way for a business to determine the level of pollution control/removal? A. Survey public opinion to find out what people think is a good amount. B. Consult with environmental scientists to determine the effects of the pollution. C. Do a cost-benefit analysis to determine the cost of removal versus benefits of removal. D. Remove all pollution, because zero pollution is achievable with enough cost.
