3 Agenda Message: Agenda Message: 3 rd quarter Report Cards go home MONDAY! CDA-IV Study is March 31 st. Study Guides go home March 24 th. Standard: Standard: Describe the causes and effects of air pollution in India & China. Essential Question: Friday March 18 th : Essential Question: Friday March 18 th : What are the physical and environmental effects of air pollution in India? Warm-up Warm-up: Name three (3) leading causes of Water Pollution along China’s Yangtze River. Today We Will: 1. Air Pollution in India

4 E. Q. Answer for Friday March 18 th : Physical effects are that many Indian people suffer from respiratory diseases (diseases of the lungs). Environmental effects are a decrease in temperatures and amounts of rainfall. Warm-up Answer: 400 million people Chemical fertilizers Industrial wastes

5 Many people in India are poor. As a result, they do not want to do anything to slow down economic growth. For this reason, it has been difficult for the Indian government to enforce many of the laws on industry and transportation that might improve the country’s air.

6 AIR POLLUTION IN INDIA Air pollution Air pollution is one of India’s most serious environmental problems. An enormous and growing population along with rapid growth of cities and development of industry have left many parts of India with some of the heaviest and most polluted air in the world.

7 Indians living in several major cities have some of the highest rates of respiratory disease (diseases of the lungs, bronchial tubes, and trachea) in the world. In addition to industrial smoke, the growing number of automobiles and trucks in India contribute to the poor air quality.

8 Some estimates say that automobile emissions (carbons and other chemicals that come from a car’s engine) are responsible for almost 70% of the air pollution problem in urban areas of India.

9 In rural areas, many families cook over open fires, using wood, animal dung, or coal as fuel.. These fuel sources send carbon monoxide, soot, and many different chemicals into the air as well.

10 This pollution can form brown clouds (haze of pollution) which reduce rainfall and temperatures.

11 AIR POLLUTION IN CHINA When the Olympic Committee decided to have the 2008 Olympic Games in Beijing, one of the concerns among the athletes who were going to compete was the quality of the air in the Chinese capital.

12 Beijing, like many other cities in China, has experienced tremendous growth in both population and industry during the past decades. Most of China’s energy is provided by burning coal, a process that sends tons of soot, ash and chemicals into the atmosphere.

13 In addition, millions of Chinese people now drive automobiles and trucks, whose exhaust or emissions is another source of massive air pollution.

14 According to the People’s Republic of China’s own statistics, the leading causes of death in China are respiratory and heart diseases that can be tied to long exposure to air pollution.

15 Acid Rain Airborne pollution also contributes to acid rain, a problem for at least a third of China’s agricultural area.

16 Acid rain occurs when chemicals in the air (especially sulfur dioxide and nitrogen oxides that come from burning fossil fuels like coal) react with the moisture in the atmosphere and fall to the ground as rain containing sulfuric and nitric acid. Acid is harmful to plants, animals and even buildings.

17 Before the 2008 Olympics, the Beijing Municipal Environmental Protection Bureau was established to work on the quality of the city’s air. Automobile traffic was greatly reduced and many factories were temporarily closed. As a result, many major air pollutants were reduced by as much as 45%.

18 Many of the people living in Beijing want the government to find ways to keep pollution down while still allowing economic progress.

19 Leaders in the World Bank make the argument that the expenses of health problems tied to air pollution are far greater than any economic profits tied to those industrial activities that contribute to the pollution.

20 The impact of environmental and health problems related to air and water pollution take many years to show up in the general population. Often governments begin clean-up efforts long after the health of a country’s population has begun to suffer.

21 . China and India have such enormous populations, almost half of the people on the planet, attention to health issues related to air and water pollution are of critical importance to all of us.
