2. As China Roars, Pollution Reaches Deadly Extremes By: New York Times
China’s industrial growth depends on coal, plentiful but polluting, from mines like this one in Shenmu, Shaanxi Province, behind a village store.

Air pollution now impeding photosynthesis and potentially wreaking havoc on country's food supply, experts warn By: The Guardian

4. China's worsening air pollution has exacted a significant economic toll, grounding flights, closing highways and deterring tourists

5. China says polluting industry still growing too fast, heavy smog alert for Beijing (By Reuters)
An electronic screen and buildings are seen amid heavy smog at the financial district of Pudong in Shanghai December 6, 2013.

6. China orders its industries to cut pollution (by The Independent Sunday 22 June 2014)
China, the world’s biggest emitter of greenhouse gases, has ordered companies in its most polluting industries to cut emissions by 30 per cent over the next four years.
“Reducing air pollution is about people’s welfare and the country’s economic future,” the State Council said in a statement. “On the one hand, smog is visible and affects the life of everyone, rich and poor. It has proven that environmental crises can stir controversy and greatly undermine social stability.”

7. A woman fetches water from the Yangtze river
A woman fetches water from the Yangtze river. Fifty families of fishermen live in Yanglingang village. They fish for their livelihood and have been drinking water from the Yangtze for decades. In the last few years, however, the river has been significantly polluted, and the fishermen noticed that the water has a strange flavor. Since 2003, factory construction has erupted all around Yanglingang. Today the little fishing village is surrounded by power plants, paper-making factories, and chemical plants.

9. Family members visit grave of Li Bairong in Shaoxing
Family members visit grave of Li Bairong in Shaoxing. He died of esophagus cancer, the exact cause unknown, becoming the fourth individual to die of cancer in his family history. The family lives in Shaoxing, an area that has been severely affected by water pollution from industry, especially the textile and dyeing industry.

10. Esophagus (food pipe)

11. Cancer sufferer Mr. Wang is one of many cancer victims from his village near Wuxi city in Jiangsu Province. While the exact causes are unknown, he believes his illness was caused by using water polluted by local industries. In February 2013, the Chinese government acknowledged for the first time the existence of "cancer villages" linked to pollution from hazardous chemicals.

12. Chen Guokang from Sanjiang village is 51 years old and diagnosed with lung cancer, the exact causes unknown. The yellow nature of his eyes and skin are due to the cancer spreading, affecting his liver, and causing jaundice. The area where he lives has been severely affected by water pollution

13. What is Pollution?
Pollution is the undesirable change in the physical, chemical or biological characteristics of air, water or land (soil) that may or will harmfully affect human life or that of other desirable species, our industrial processes, living conditions or cultural assets or that may or will waste or deteriorate raw material resources.
Pollution causes risks to environmental quality, human health and damage to natural resources.

14. What is Pollutant ?
A substance or condition that contaminates air, water, or soil.
Pollutants can be artificial substances, such as pesticides and PCBs, or naturally occurring substances, such as oil or carbon dioxide, that occur in harmful concentrations in a given environment.

16. POLLUTION CONTROL (PC)
(The end of pipe method: producing wastes firstly, then later thinking of how to manage it)

17. Industrial wastes

18. Activated sludge treatment plant

19. Wastewater (liquid)
Excess sludge
(solid)

20. Sludge disposal/treatment

21. Pollution Control Solve no problem
It only alters the problem, shifting it from one form to another.
It takes resources to remove pollution, pollution removal generates residues, it make more resources to dispose of this residue and disposal of residue also produces pollution.

22. Pollution Prevention (P2)
Meaning thinking beforehand how to reduce waste before it will be produced.
Waste is simply material that is not being used efficiently.

23. Pollution Prevention (P2)
Basically, it means prevent or reduce the sources of pollution before problems occur.

24. Pollution Prevention (P2)
Includes practices that reduce OR eliminate the creation of pollutants through increased efficiency in the use of raw materials, energy, water, or other resources, or protection of natural resources by conservation.
Involves waste minimization, source reduction, design for the environment, and clean technology.
Since a number of pollution control measures apply only AFTER wastes have been generated, they cannot be called Pollution Prevention.
