1 Pollution in AsiaDescribe the causes and effects of air pollution and flooding in India and China.Describe the causes and effects of pollution on the Yangtze and Ganges Rivers.
2 Air Pollution Asian Brown Cloud Causes: 2 mile deep brown haze Respiratory problemsClimatic ChangesFloodsAcid rainBlocks SunlightDestroys cropsCauses:IndustrializationHigh population in Urban areasBurning wood and other biomass materialMany areas lack electricity or other cleaner energy sources
6 Air PollutionChina’s is the world’s fastest growing economies—with no environmental regulationIndia has some 500,000 annual deaths from indoor air pollutionBangladesh has about 100,000 annual deaths from indoor air pollution
7 India’s Environmental Concerns India’s main environmental concern is overpopulation.It affects many of India’s other issues.India’s population is expected to be about 1.6 billion by 2050.Such a large number of people will put a strain on groundwater supplies.More water is needed to irrigate crops to keep up with the food supply.If artificial fertilizers are used on crops, then drinking water may be affected.
8 India’s Environmental Concerns Rivers such as the Ganges and groundwater are also polluted by toxic waste from industry.Industry and vehicles pollute the air.India has many small industrial workshops.Because of this, it is difficult for the government to enforce laws to improve air and water pollution
9 Ganges River India’s most sacred river Used for funeral ritesCremated bodies(not) cremated bodiesUsed by millions for drinking and bathingPoor sewage systems drain directly into the river
14 China’s Environmental Issues China’s fast industrial development and the large population have created major problems for the environment.Pollution has increased and natural resources have been depleted.Seven of the world’s ten most polluted cities are in China, according to a World Health Organization report.
15 China’s Environmental Issues Feeding the Chinese people is a huge task. Much of the food production occurs on the North China Plain.The fertility of this plain is mostly because of the Huang He (Yellow River).The Huang He used to regularly flood over its banks, often destroying crops.This river is sometimes referred to as “China’s Sorrow.”To combat the widespread and disastrous flooding, the Chinese government has carried out large flood control and irrigation projects since 1949.
16 China’s PopulationTo handle the population problem in China, the government instituted a one-child-per-family policy in 1979.Couples that have only one child receive economic and educational benefits, while in cities, couples that have more than one child pay fines.This population control policy has not been as successful as was hoped.Many Chinese babies are put up for adoption.
17 Yangtze River China’s longest river - 4,000 miles from the Northwest regions to the East China SeaPasses through over 185 towns and villages (400 million people)Poor sewage drains millions of gallons into the riverFertilizer run-off into the riverMillions of people use the river to catch fish (most have been contaminated by factory chemicals)
18 Yangtze River Three Gorges Dam Pros: Cons: Provide millions with Hydroelectric powerControl flooding in certain areasCons:Many plants and animals living near the river may face extinctionBuilt on an area prone to Earthquakes!
