Water pollution
"Man is a complex being; he makes the deserts bloom and lakes die."
— Gil Stern Pesticides are carried in rainwater from farm fields, suburban lawns, or roadside embankments into creeks. Results: affect and damage the nervous system; cause liver damage; damage DNA and cause a variety of cancers; cause reproductive and endocrine damage; cause other acutely toxic or chronic effects. "Society, my dear, is like salt water, good to swim in but hard to swallow."
— Arthur Stringer, author, The Silver Poppy Mercury comes through air pollution from industrial plants. In the water, the elemental mercury is converted to methylmercury by certain bacteria, after which it moves into food through a fish. Young children and fetuses (плод) are most at risk because their systems are still developing. Mercury causes neurological problems, including slower reflexes, learning deficits, delayed or incomplete mental development, autism, and brain damage. Mercury for adults is also a problem, causing: central nervous system effects like Parkinson's disease, multiple sclerosis, and Alzheimer's disease (разновидность пресенильного слабоумия); heart disease; death or irreversibly damaging areas of the brain.
