As China's population grew, so did the nation's economy and its appetite for natural resources. Even with China's 'one-child policy,' the ecological impact is huge.

XIAMEN, China — A 6-year-old girl with a bob haircut sat alone on an enormous wraparound couch, dwarfed by the living room furniture and a giant flat-screen TV.

As she flicked the remote in search of cartoons, her parents pointed proudly to the recessed lighting and high ceilings. Then they proceeded with an official tour of their three-story house with white marble floors, oversized windows and a granite entryway flanked by a Corinthian column.

"Many of my friends envy me," Zhang said, mopping sweat from his neck as a dozen local officials and family planning bureaucrats looked on. The couple had been given a day off work to showcase the benefits of their restraint to two foreign journalists.



The aim was to banish hunger and raise living standards, and by many measures the results have been impressive. By reducing the number of dependents per household and freeing more women to enter the workforce, population control efforts have helped lift hundreds of millions of people out of poverty and contributed to China's spectacular economic growth.

Prosperity has exacted a steep environmental toll, however.

The colossal industrial expansion of recent decades has depleted natural resources and polluted the skies and streams. China now consumes half the world's coal supply. It leads all nations in emissions of carbon dioxide, the main contributor to global warming. Pollutants from its smokestacks cause acid rain in Seoul and Tokyo.



Moreover, the Chinese are living better overall: consuming more food, energy and goods than ever. One-fourth of the population — the equivalent of everyone in the United States — has entered the middle class.

The U.S. consumes much more per person. But with a population four times larger, China has a greater collective appetite — and a greater ecological impact — than any other country.

The compounding forces of economic and population growth are a source of increasing concern to scientists. An international team of 1,300 researchers organized by the United Nations concluded that evidence points to "abrupt and potentially irreversible changes" in ecosystems in the next few decades, including mass extinctions and rapid climate change.

Within China, signs of environmental damage are pervasive: massive fish kills, lung-searing smog, denuded landscapes. They have stirred popular discontent and the beginnings of greater official concern for curbing pollution and preserving natural resources.

How this drama plays out is not merely China's concern. Because of the nation's sheer size, the rest of the world has an enormous stake in the outcome.

"To solve China's problems is to solve the world's problems," said Yu Xuejun, a director-general in the country's National Population and Family Planning Commission.

China's massive population is a legacy of Communist Party Chairman Mao Tse-tung, who strove to increase the ranks of the Red Army by encouraging large families and banning imports of contraceptives and declaring their use a "capitalist plot."

In the late 1950s and early 1960s, a series of famines claimed tens of millions of lives. The suffering left an enduring awareness that the country couldn't sustain unlimited population growth.




Yu, the family planning official, acknowledged that the policy has caused hardships.

"I myself sacrificed," he said, explaining that he forfeited his own dreams and disappointed his father by failing to produce a son. He and his wife had one child, a daughter.

There is widespread recognition [in China] that natural underpinnings of human prosperity are at grave risk.”

But he said such forbearance benefited the country, creating a bulge of working-age people with fewer dependents. The resulting burst in productivity is known as the demographic dividend.

Those who work for the vast family planning bureaucracy take great pride in what they see as their contributions to China's prosperity.

On a five-day tour of the homes of in-policy families, arranged for two Times journalists, officials toasted their achievements every night, feasting on dishes of beef, pork, duck, chicken and fish.

In discussing the country's population policies, the giddy bureaucrats turned again and again to the economic rewards. "We want to get rich before we get old," was a common refrain.


In Shanghai, whose population of 23 million exceeds that of Australia, high-rises sprawl in all directions until their silhouettes slip from view, obscured by brown haze.

China, by varying estimates, has more than 100 cities with 1 million or more residents, compared with 9 in the United States. The number of million-plus cities will reach 221 within two decades, according to the McKinsey Global Institute, an economics research firm. More than a dozen will have populations of 25 million or more each.


Away from the urban center, farms give way to neat rows of town houses and multistory condominiums.

All this development is being stitched together with high-speed rail and new highways to prepare for 600 million vehicles expected on the roads by 2050.

The U.S. automotive fleet, by far the largest in the world, is less than half that size.

"Of course I feel bad," said He, walking across the remains of a red-clay slope on his farm that washed away that day. "There was a flood here and there was a flood there. It was the same water."

The inundations across central China drowned more than 3,000 people, destroyed 13 million homes and caused at least $24 billion in damage.

The catastrophe also changed the way China viewed trees.

Chinese leaders issued a broad ban on logging and launched an enormous replanting program.

In the last decade, the government has spent more than $90 billion to plant trees across millions of acres and pay farmers to nurture them. An enormous sign just up the hill from He's farm proclaims, "Keep the trees, protect Mother Yangtze River."

The reforestation has turned China greener — literally. Scientists have noticed the change on satellite images: Forest cover has expanded from 12% to 20% of the country.

At least in this case, China learned the consequences of heeding Mao's exhortation to subjugate nature.

"Harmonizing people and nature — that's how high government discussions frame China's future development," said Stanford University ecologist Gretchen Daily, who has studied China's reforestation. "There is widespread recognition that natural underpinnings of human prosperity are at grave risk."

The solutions are not always as straightforward as planting trees.

A red truck arrived with a squeal of brakes and a swirling cloud of black dust.

The driver peeled back a tarpaulin to reveal his cargo: coal to stoke one of the massive electricity plants in Shanxi province.

The procession of dump trucks continued around the clock, leaking coal dust that piled up along the road like drifts of black snow. Squat cooling towers hissed like fumaroles. Slender smokestacks disgorged white-gray smoke carried east by the breeze, toward Beijing and beyond.

In nearby Datong, a thick gray-brown haze clings to the city like a dark mist, obscuring the tops of high-rises.

A half-day's drive south is the ancient city of Linfen, identified by the World Bank six years ago as the most polluted city on Earth.

The city, once known for its fruit and flowers, is now infamous for respiratory illnesses and the shroud of smog that regularly blots out the sun. When the sun does manage to poke through, it appears as a burnt orange fireball, reminiscent of Southern California's eerie skies during raging wildfires.


Tendrils of soot extend across the Pacific. On some days, almost 25% of the pollutants in the air above Los Angeles originated in China, the Environmental Protection Agency has found.

Under international pressure, China has cracked down on some of its dirtiest plants, mainly to reduce soot or pollutants like sulfur dioxide, which causes acid rain and aggravates asthma and heart disease.

After the World Bank's rebuke, officials in Shanxi province closed some of the illegal coal mines in Linfen and its dirtiest coal-fired furnaces.

Chen Mai Zhi, a stout middle-aged woman in black capri pants, said her headaches and dizzy spells have receded, but she still avoids wearing light-colored clothes and doesn't hang laundry outdoors because of the soot.

Wang Shu Quing has also noticed a difference. The smokestacks bordering her cornfield just north of Linfen no longer cough up black smoke. "They did something inside to change it," Wang said. "Now you can see the smoke only once in a while."

Such steps reduce pollution at the local level. But they do nothing to curb China's consumption of coal or the resulting carbon dioxide emissions.



Those trends are worrisome to climate scientists, who say that in order to avoid a potentially catastrophic rise in global temperatures, worldwide carbon dioxide emissions must be cut in half by 2050.

For that to happen, China's emissions would have to peak by 2020, said Nobuo Tanaka, former director of the Paris-based International Energy Agency, which advises governments on energy issues. But by China's own projections, its output will rise at least 50% from current levels before peaking around 2035.

It would be all but impossible for other nations to compensate for such an increase, Tanaka said.

Chinese leaders say that capping emissions would cripple industrial growth and urban development in a country that still has 100 million poor people.

The industrialized countries polluted their way to prosperity, their argument goes, so why should the Chinese be penalized?

China's leaders also have sought credit for their population control policies, which they say averted 400 million births and thus billions of tons of greenhouse gas emissions.

At the same time, they acknowledge that the one-child policy was never meant to be permanent. When it was started in 1979, officials promised to revisit the issue in 30 years. There is some internal pressure and even more international pressure to lift the restrictions.

That worries Yu Xuejun, the director-general with the National Population and Family Planning Commission. The best course, he said, would be "a soft landing" with "incremental adjustments" so that the sacrifices he and others made in forgoing larger families are not erased by a baby boom.

"I cannot imagine if we had 400 million more people in China," he said.
