Answer:

1.Humans impact the physical environment in many ways: ∞overpopulation, pollution, burning fossil fuels, and deforestation∞. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water

2.∞Hazardous air pollutants∞ -Almost 200 are regulated by law; some of the most common are mercury, lead, dioxins, and benzene. ... Lead in large amounts can damage children's brains and kidneys, and even in small amounts it can affect children's IQ and ability to learn. Mercury affects the central nervous system.
