Answer:
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.Many times in these cases, the pollution is caused by chemical dumping from nearby factories. Dumping of industrial chemicals, agricultural waste, and urban wastewater has contaminated China's water resources such that over half of all rivers in the country are unsafe for human contact.China's sweeping campaign to cleanse filthy lakes and rivers has improved water quality in some regions — but dirty water still plagues parts of the country. China began tightening environmental rules in 2001, in an effort to cut water pollution emitted by cities, industrial facilities and farms.Dam construction has played significant roles in flood control, irrigation, navigation, and energy supply; however, the enormous negative effects, such as landslides, ecological problems, and water quality decline, could surpass positive gains.
Answer:
Why did the United States choose to stay neutral in 1914? ... Put simply the United States did not concern itself with events and alliances in Europe and thus stayed out of the war. Wilson was firmly opposed to war, and believed that the key aim was to ensure peace, not only for the United States but across the world.
By maintaining their neutrality from the onset of the war, they hoped to profit from all belligerents by manufacturing munitions, hence promoting their own economic growth and industrial prosperity. ... The United States took issue with the increasing belligerence of Allied forces, particularly the British.
