NEET BIOLOGY

Detailed explanation-1: -China’s water supply has been contaminated by the dumping of toxic human and industrial waste. Pollution-induced algae blooms cause the surface of China’s lakes to turn a bright green, but greater problems may lurk beneath the surface; groundwater in 90 percent of China’s cities is contaminated.

Detailed explanation-2: -China consumes almost as much coal annually as all other countries combined, and coal burning in the country is the biggest source of both air pollution and greenhouse gas emissions, the leading cause of climate change. Chinese cities are among the most polluted in the world.

Detailed explanation-3: -One of the major sources of air pollution in China and India is from sulfur-dioxide emissions. The major contributor to the sulfur-dioxide emissions is due to increased coal consumption in the industrial sectors in both countries. More than 70% of China’s energy still comes from brown coal, the dirtiest fuel of all.

Detailed explanation-4: -Water consumed by people in China contains dangerous levels of arsenic, fluorine and sulfates. An estimated 980 million of China’s 1.4 billion people drink water every day that is partly polluted. More than 20 million people drink well water contaminated with high levels of radiation.
