Unformatted text preview: tracts of humans and other animals Note : Some pollutants may not have direct health effects. Choose one of the following atmospheric issues: air pollution, global warming, ozone depletion, and acid deposition. Then, respond to the following: • What air pollutants combine and contribute to this issue? Oxygen and nitrogen atoms can react to create nitrogen oxides when placed under extreme pressure and temperature within engines. Nitrous oxide is approximately 7.2% of the gases causing global warming. • Briefly describe the health and environmental problems caused by the selected atmospheric issue. These toxins also cause several human and environmental difficulties, like acid rain, smog, and respiratory problems. • Provide one key solution to help either reduce the effects or recover from the effects of the selected issue. In an effort to reduce global warming, society could reduce drive time by walking, or biking. SCI 275...
