If there is an excessive amount of air pollution, it can cause coughing, panting, or irritation. Additionally, bodily harm, including cancer, can result from prolonged exposure to pollutants. (“Effects of air pollution on health and the environment”). Air pollution can have harmful effects on the environment, such as the destruction of the ozone layer. The stratosphere, which includes the ozone layer, protects the Earth from harmful UV rays. This layer is destroyed by chemicals found in coolants, pesticides and aerosol propellants. UV rays can thus reach the Earth more easily. This could potentially lead to more health problems and damage to sensitive crops (“Health and Environmental Effects of Air Pollution”). Acid rain, created by air pollution, can also affect crops by turning soil acidic and making water habitable for wildlife. Another problem related to air pollution is global warming. The atmosphere contains greenhouse gases that are responsible for maintaining stable temperatures and warmth from the sun on Earth (“Health and Environmental Effects of Air Pollution”). By burning fossil fuels, humans emit greenhouse gases. The transport of greenhouse gases leads to global warming. Negative consequences of global warming include: wildlife, agriculture and even health problems (“climate change impacts”). Ozone layer destruction, acid rain and global warming are just some of the negative impacts caused by air.
