Explanation:

2. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

6. It can lead to food poisoning). The result: dangerous diseases like cholera and typhoid fever. Other waterborne diseases include diarrhoea, dysentery, polio and meningitis. Unclean water for washing can cause skin and infectious eye disease such as Trachoma.

7. Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. ... UV rays also affect plant growth, reducing agricultural productivity.

8. Oil spills frequently kill marine mammals such as whales, dolphins, seals, and sea otters. ... Oil coats fur of otters and seals, leaving them vulnerable to hypothermia. Even when marine mammals escape the immediate effects, an oil spill can contaminate their food supply.

11. Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.
