Which statement below about Rachel Carson and her contributions to environmental awareness is true? She wrote an important book that closed the gap between biological and social sciences by examining the interactions between all living things. She wrote in 1949 that humans and nature depend on one another and humans are ethically obligated to protect the environment. She died in 1862, but she had great influence shaping the philosophy of modern-day environmentalism with early calls for protected wildlife areas. She published a book in 1962 about the effects of agricultural use of chemicals and pesticides on the environment and spurred a new national awareness of the environment.

Consumers experience dizziness and nausea from pollutants in the water supply. The consumption of fossil fuels contributes to air pollution and rising CO2 levels. Formaldehyde in the new office carpeting is causing a severe allergic reaction. Particulate matter from a coal factory is causing health problems for workers. The consumption of fossil fuels contributes to air pollution and rising CO2 levels. Which of the following is NOT a consequence from the runoff of fertilizers into the water supply? Oxygen levels in water increase. Fish die due to toxins. Algal blooms take over a body of water. Tainted drinking water leads to human disease. Oxygen levels in water increase. When analyzing environmental issues, scientists try to predict future states or events, which is difficult because so many factors are unknown. Nevertheless, predictions are valuable for determining and managing risk. Select the FALSE prediction for the future of the environment. Global temperatures are expected to increase by up to ten degrees over the next hundred years. Overexploitation of plants and animals will decrease as endangered species legislation is enforced. Water pollution is expected to continue to deteriorate both ocean and fresh water quality. Fewer forests will mean more greenhouse gases in the atmosphere. Overexploitation of plants and animals will decrease as endangered species legislation is enforced. Which list correctly orders the examples of organism, population, community and ecosystem?
