The Chinese government has been quietly making big investments in the metals industry since the country began industrializing in the 1970s.
At the same time, the government is making efforts to cut pollution, with some of the world’s top companies, including major companies such as ExxonMobil, mining giant BHP Billiton and steel giant BAE Systems, investing in China’s major metal processing plants.
That shift is helping to fuel China’s economy, but some in the industry are concerned about the environmental impact of that expansion.
The country’s rapid industrialization and massive mining operations have contributed to the country’s high pollution levels.
A study published last month in the journal Environmental Research Letters found that pollution from China’s coal and steel industries is the world-leading contributor to global warming and climate change.
The researchers said that pollution is more likely to be released into the atmosphere when heavy industry is concentrated in a few cities than in smaller, less densely populated areas.
“The pollution in the coal and iron ore industries is huge,” said David Rennie, an economist with the Center for Global Development at the University of Pennsylvania.
“That’s why the [Environmental Protection Agency] and the [United Nations] have taken it seriously.”
China’s expansion is also contributing to the Chinese economy’s slowing growth.
China’s gross domestic product has shrunk to 4.3 percent of its total economic output in 2016 from 6.9 percent in 2000, according to data from China International Business Machines Corp. The economy grew only 2.3 percentage points in 2016.
In comparison, the U.S. economy grew 8.4 percent in 2016, according a report by the National Bureau of Economic Research.
The economic slowdown has created a growing number of environmental concerns, including concerns about coal-mining pollution.
A major challenge is that China’s massive mining sector requires massive amounts of land, and its heavy industry produces coal and other heavy materials.
To build factories and other factories, coal and heavy materials are transported to far-flung locations and dumped into the sea, which can be inhaled, a problem that can exacerbate the health problems of people living nearby.
“This is not a problem in America, and we’re doing the same thing,” said Bill Johnson, a professor at the Johns Hopkins School of Advanced International Studies.
The U.N. estimates that China has more than 100,000 coal mines and mines that are used for steelmaking, cementing, making bricks, and other uses.
The coal industry is the largest contributor to China’s carbon emissions.
The United States has the most coal-fired power plants in the world, but it has not built nearly as many as China, Johnson said.
“It’s a problem.
We’ve got to do something about it,” he said.
The government has stepped up efforts to reduce the countrys carbon footprint, but critics argue that the government hasn’t been doing enough.
The World Health Organization has called China’s pollution levels a “public health emergency,” and it said in 2016 that China “has the highest rate of air pollution of any country in the industrialized world.”
China has pledged to reduce its carbon emissions by 50 percent by 2030, but the government has yet to do much to make up for those gains.
“We’re not getting any real progress,” said Zhang Xiaozhen, a Beijing-based professor of environmental economics at the China Academy of Social Sciences.
“They’re not building anything.
They’re not doing anything.
The Chinese are just not doing their part.”
Zhang is not alone in his concerns.
“There is a lot of anger, a lot [of] resentment,” said James Whelan, an analyst with the American Council on Science and Health.
“People are saying to me: ‘What the hell is going on?’ “
