1 Environmental Issues Across Southern and Eastern Asia SS7G10 The student will discuss environmental issues across Southern and Eastern Asiaa. Describe the causes and effects of pollution on the Yangtze and Ganges Riverb. Describe the causes and effects of air pollution and flooding in India and China
2 E. Q.How does pollution affect the Ganges and Yangtze Rivers and the people who live near them?
4 Ganges RiverBegins in Himalayan Mountains and flows 1600 miles through India into Bangladesh and the Bay of Bengal.Provides water and transportationKnown as “Mother Ganges”The Ganges River basin is one of the most fertile and densely populated in the world
5 Ganges River Pollution Chemicals (farming, industry) wash into water every day.Human (cremation) and animal waste (dead bodies) pollute the riverSewage from nearby cities is dumped into the water
6 Think Pair Share Discuss with a partner How does the pollution of the Ganges effect the 400 million people that live nearby?
7 Ganges River pollution Continued The poor rely on the Ganges River on a daily basis for bathing, washing, and cookingthe Ganges River is considered holy, and ritual bathing in its waters is practiced by an estimated 60,000 people per dayCities along the Ganges have the highest rates of water-born diseasesIt has been suggested that 80% of all illnesses in India and 1/3 of deaths can be attributed to water-borne diseases.
8 A woman with a skin disease rests near offerings and trash on the banks of the Ganges in Kanpur, India.
9 Ganges River Pollution India created the 1985 Ganges Action Plan, to clean up the riverMany sewer and water treatment plants have been built along the riverHowever, pollution remains a huge problem today due to the growing population and run-off from industries and farmsApril 14, 2013
11 Yangtze RiverChina’s longest river, flows over 4000 miles to the East China SeaAround 400 million people live in the areaRiver is used for industries, drinking, and irrigation
12 Yangtze River Pollution The Yangtze River is being polluted by sewage, agricultural (nitrogen from fertilizers), and industrial waste (arsenic – poison!)Many of the plant and fish species are dying and the Yangtze could become a dead riverHigh levels of nitrogen & phosphates lead to growth of blue-green algae – reduces oxygen & kills fishPeople eat contaminated fishPollution greatly affects the cities’ water supply
13 Yangtze River Pollution The government built the Three Gorges Dam on the Yangtze River to provide hydroelectric powerThe dam has altered the environment upstream by flooding populated areas and threatening plants & animals with extinctionThe dam was built in an area prone to earthquakes (!)
16 SolutionsChina is building water treatment plants to remove pollutants from the waterChina encourages cities to build landfills rather than dumping garbage into the riverThe World Bank helps organize these programs

20 CRCT Test Prep pages 134-137 3. Which is true about the Ganges River? The river is ignored by Indian religious rituals.People do not drink the water because it is so polluted.Many people use the river for transportation as well as a water supply.Plant and animal life have not been affected by the poor quality of the river’s water.C. Many people use the river for transportation as well as a water supply.
21 CRCT Test Prep pages4. How has India’s need to develop more industry ended up creating problems along the Ganges River?Factories along the river dump industrial waste and chemicals into the river every day.No one is allowed to cremate dead bodies along the river since the large factories have been built.Industries along the river use so much water that the Ganges is almost dry by the time it reaches the sea.Factory owners have refused to allow the Indians living along the river to bathe in the water or use the water for cooking.A. Factories along the river dump industrial waste and chemicals into the river every day.
22 CRCT Test Prep pages5. How has the Indian practice of cremating their dead been a problem for the river?People are not allowed to go near the river when cremations are taking place.The banks along the river regularly catch fire and threaten Indian homes built there.Factory owners cannot use water once human ashes have been thrown into it upstream.The bodies of dead animals, as well as the ashes of human beings, have been placed in the water causing pollution.D. The bodies of dead animals, as well as the ashes of human beings, have been placed in the water causing pollution.
23 CRCT Test Prep pages6. What was the purpose of the Ganges Action Plan begun in the 1980s?To try and clean up the riverTo bring an end to the cremationsTo end using the river for drinking waterTo slow down the building of new factoriesA. To try and clean up the river
24 CRCT Test Prep pages7. Why has the Indian government had such a hard time making much progress in cleaning up the Ganges River?Most people in India feel the river is not polluted so they are not worried about it.The government of India has not made the cleaning up of the Ganges River one of its goals.Few people have gotten sick from the water in the Ganges River, so it is hard to get money for clean-up operations.India’s combination of growing population and run-off from farming makes it hard to see much progress in controlling pollution.D. India’s combination of growing population and run-off from farming makes it hard to see much progress in controlling pollution.
25 CRCT Test Prep pages8. Why is the Yangtze River so important to the population and economy of China?Water from the Yangtze River is used to irrigate the Gobi Desert.The Yangtze River is the international border between China and India.People can use the Yangtze River to get over the Himalayan Mountains.It supplies millions of people with water for drinking, irrigation, and industrial uses.D. It supplies millions of people with water for drinking, irrigation, and industrial uses.
26 CRCT Test Prep pages9. Into what body of water does the Yangtze flow?Indian OceanBay of BengalEast China SeaSouth China SeaC. East China Sea
27 CRCT Test Prep pages10. What are some of the main causes of high levels of nitrogen in the Yangtze River?The waste is from nuclear power plants.The bodies of dead animals are thrown into the river.The chemicals used in fields run into the river.The exhaust fumes from the millions of cars run into the river.C. The chemicals used in fields run into the river.
28 CRCT Test Prep pages11. Which is one of the most common industrial pollutants found in the Yangtze River?ArsenicNitrogenNuclear wasteHuman sewageA. Arsenic
29 CRCT Test Prep pages12. What has been the effect of the rapid growth of algae in the Yangtze River?The oxygen levels in the water go down and fish die.The river dolphins and porpoises can rely on the algae as a food source.The Yangtze River can no longer be used for shipping and transportation.The algae have provided a good source of fertilizer for those who live along the river.A. The oxygen levels in the water go down and fish die.
30 CRCT Test Prep pages13. Why did the Chinese government decide to go ahead with the Three Gorges Dam project along the Yangtze River?The dam would provide water for all of China’s desert areas.China’s people needed a reliable source of hydroelectric power.China needed to be able to store water because the Yangtze river often dried up in the summer.Careful study showed there would be no environmental problems associated with the dam.B. China’s people needed a reliable source of hydroelectric power.
31 CRCT Test Prep pages14. How would building sanitary landfills along the Yangtze River help reduce pollution in the water?The garbage could go into landfills instead of in the river.The landfills would reduce the general need for more electricity.The chemicals would no longer run into farmers’ fields and into the river.All of the garbage would be recycled in landfills and there would be no waste.A. The garbage could go into landfills instead of in the river.
32 India – Air PollutionThe capital city of New Delhi is one of the top 10 most polluted cities in the world.
33 Air Pollution in India Air Pollution Causes: Growing population, rapid growth of cities, development of industry, & automobile emissions (main cause) are leading causesThe Asian Brown Cloud is a layer of air pollution that covers parts of India & looks like a brown stainCaused by cooking over open firesPollutes air inside homes alsoBrown cloud reduces rainfall and temperaturesEffects: Air pollution leads to high levels of respiratory diseases (breathing) (some of highest rates in the world)Solution?: Many poor people do not want to slow down economic growth, so government has problems enforcing pollution laws
34 China: Air Pollution 2008 Olympics – held in Beijing, China The athletes were worried about the air pollution in Beijing (caused by burning coal for fuel and the millions of cars and trucks)The Chinese government set up the Beijing Municipal Environmental Protection BureauTask: clean up the airHow: limit automobiles and temporarily close factoriesResult: 45% reduction in air pollutants
35 China –Air Pollution Causes Fossil fuels:CoalFor industry and heating homes.Coal is cheap but pollutes the air.FactoriesVehicles
36 China - Effects of Air Pollution Up to 656,000 premature deaths each year from respiratory and heart diseaseAcid rain – causes crop damageClimate changeOnly 1% of people in cities breathe safe air
37 International Concern World Bank leaders encourage countries to clean up serious environmental problems quickly.The long-term costs of pollution (cancer, heart disease, lung diseases, extinctions of plants and animals) are more expensive than the clean-up effort.China and India have almost ½ the people on the planet; reducing their pollution will prevent many health problems.
38 China & India - Flooding Heavy rainfall in monsoon seasonRivers overflow banksDeforestationno trees to absorb waterAffects water supply by damaging sewage plantsCauses serious illnesses like malaria and choleraCrops are destroyed causing huge financial losses
39 Effects of Flooding – China/India Deaths [Worst Recorded Flood: Huang He River, China, August 1931 (3,700,000 people)]Homes/villages destroyedPossessions lostFertile land washed away
