What happened to China?: the nation's environmental woes and its future

"During the past 60 years, negative impacts have been stronger than positive ones, with most environmental conditions worsening and few improving," writes Jianguo Liu, MSU University Distinguished Professor of fisheries and wildlife who holds the Rachel Carson Chair in Sustainability.

"The widespread ideology of 'development first, environmental protection later' or 'pollute first, then clean up' is a root cause of China’s low ranking in environmental sustainability," Liu writes.
One of China's boldest plans to deal with environmental problems and overpopulation was the 'one-child policy' implemented in 1979. It is estimated that this policy slowed China's population growth by approximately 300 million people over twenty five years. Yet, changes in Chinese society have offset some of the environmental benefits one would expect from slowing population.
While China's population growth slowed, the number of new households increased faster than the nation's population. Between 1985 and 2000, China added 125 million new households due to social changes, such as increased divorces and less multigenerational households, cutting the average number of people living in each house.
"More households consume more resources and generate more waste, and smaller households lower the efficiency of resource use," Liu writes.

Moving forward the government should enact new policies to stem the growth of new households, according to Liu. "One idea may be to create government incentives such as tax credits or subsidies to promote multigenerational housing and housing shared by friends and other non-family members and to discourage divorce".
Liu points out that there has been some sizable movement towards sustainability recently: just over 15 percent of China is now protected as natural reserves; logging of natural forests has been banned since 1998; and the government has pledged to cut CO2 emissions intensity per unit of GDP by 40-45 percent by 2020 from 2005 levels. China is moving aggressively on clean energy, outpacing both the US and the EU in green investments. Still, while the nation has put in place many environmental laws, Liu says these regulations need better implementation and monitoring.
"China is the most populous country with the fastest growing economy in the world—everything it does has a big impact," Liu adds. "Environmental sustainability in China is crucial, not just for China, but for the rest of the world."

Consumption habits cause rich countries to outsource emissions
(03/08/2010) Over a third of the greenhouse gas emissions related to the consumption of goods in wealthy nations actually occur in developing countries, according to a new analysis by researchers with the Carnegie Institution. Annually, each person if the United States outsources 2.5 tons of carbon due to consumption habits, most frequently in China. In Europe the figure of 'outsourced' emissions rises to 4 tons per person.
Extinct animals are quickly forgotten: the baiji and shifting baselines
(02/23/2010) In 2006 a survey in China to locate the endangered Yangtze River dolphin, known as the baiji, found no evidence of its survival. Despondent, researchers declared that the baiji was likely extinct. Four years later and the large charismatic marine mammal is not only 'likely extinct', but in danger of being forgotten, according to a surprising new study 'Rapidly Shifting Baselines in Yangtze Fishing Communities and Local Memory of Extinct Species' in Conservation Biology. Lead author of the study, Dr. Samuel Turvey, was a member of the original expedition in 2006. He returned to the Yangtze in 2008 to interview locals about their knowledge of the baiji and other vanishing megafauna in the river, including the Chinese paddlefish, one of the world's largest freshwater fish. In these interviews Turvey and his team found clear evidence of 'shifting baselines': where humans lose track of even large changes to their environment, such as the loss of a top predator like the baiji.
Chinese farming practices are acidifying soils
(02/11/2010) A new study in Science shows that farming practices in China are acidifying the nation's soils and threatening long term productivity at a time when food concerns worldwide have never been higher. The culprit is the increasing use of nitrogen fertilizer.

China leaves US (and Europe) in the dust on renewable energy
(02/01/2010) This year China has become the world's largest manufacturer of solar panels and wind turbines, doubling its wind capacity since 2005. The economically booming nation—and the world's most populous—has also invested heavily in nuclear power and the world's most efficient coal plants, according to the New York Times.
Iceland leads world on environmental issues, but China, US, and Canada plummet
(01/27/2010) Evaluating 163 nations on their environmental performance, the Environmental Performance Index (EPI) has named Iceland the most environmental nation. Released every two years, the EPI also found that the world's two largest super-powers—China and the US—have both fallen behind on confronting environmental challenges.

Illegal logging trade from Myanmar to China slows, but doesn't stop
(10/28/2009) The illegal wood trade from Myanmar to China has slowed, but it still threatens Myanmar's tropical forests and species, according to a new report by Global Witness. From 2005 and 2008 improved border controls into China led to a drop in imports of logs and sawn wood by 70 percent.
The Yangtze River may have lost another inhabitant: the Chinese paddlefish
(10/22/2009) In December of 2006 it was announced that the Yangtze River dolphin, commonly known as the baiji, had succumbed to extinction. The dolphin had survived on earth for 20 million years, but the species couldn't survive the combined onslaught of pollution, habitat loss, boat traffic, entanglement in fishing hooks, death from illegal electric fishing, and the construction of several massive dams. Now, another flagship species of the Yangtze River appears to have vanished.
Major Chinese Lead Smelter Admits Fault in Poisoning, Environmental Contamination
(10/17/2009) The largest lead smelting company in China has recently admitted responsibility in contributing to pollution leading to poisoning in almost 1,000 children residing near lead factories. Out of 2,743 children tested for lead poisoning, 968 were determined to have excessive lead levels in their blood. Lead poisoning causes anemia, brain damage, and muscle atrophy, among other serious medical and environmental problems. Lead levels in blood samples from the children were 5 times higher than safe limits.
