1 . New research links outdoor air pollution — even at levels considered safe — to an increased risk of diabetes (糖尿病) globally, according to a study from the VA St. Louis Health Care System. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.
Diabetes is one of the fastest growing diseases, affecting more than 500 million people worldwide. The main drivers of diabetes include eating an unhealthy diet, having a sedentary lifestyle and obesity, but the new research indicates the extent to which outdoor air pollution plays a role.
“Our research shows a significant link between air pollution and diabetes globally,” said Ziyad Al-Aly, MD, the study’s senior author and an assistant professor of medicine at the University of Washington. “We found an increased risk, even at low levels of air pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO). This is important because many industry lobbying (游说) groups argue that current levels are too stringent and should be relaxed. Evidence shows that current levels are still not sufficiently safe and need to be tightened.”
While growing evidence has suggested a link between air pollution and diabetes, researchers have not attempted to quantify that burden until now. “Over the past two decades, there have been bits of research about diabetes and pollution,” said Al-Aly. “We wanted to thread together the pieces for a broader, more solid understanding.”
The researchers also found that the overall risk of pollution-related diabetes tilted (倾斜) more toward lower-income countries such as India that lack the resources for environmental mitigation systems and clean-air policies. For instance, poverty-stricken countries facing a higher diabetes-pollution risk include Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experience a lower risk. The US experiences a medium risk of pollution-related diabetes.

3 . Most of the efforts aimed at reducing climate change centering on reducing the use of fossil fuels. But a new study warns that pollution caused by the world’s food production system is also a major driver of rising temperatures on the planet. The study found that if the world food system stays on its current growth path, it will produce nearly 1.4 trillion tons of greenhouse gases over the next 80 years. That pollution is expected to come from chemical fertilizers used in agriculture, mismanaged soil, food waste and methane (甲烷) gas released from cows and other animals.
Researchers from the University of Minnesota and the University of Oxford in Britain led the study, which recently appeared in the publication Science. The researchers predict that even if fossil fuel emissions (排放) were halted now, emissions from the world food system would make it impossible to reach current international climate change targets. They say that emissions from food production alone could push world temperatures past 1.5 degrees Celsius by the middle of this century and above 2 degrees Celsius by the end of the century.
A main goal of the 2015 United Nations Paris Agreement on climate change is to keep rises in the Earth’s temperature during this century to between 1.5 to 2 degrees Celsius. The U. N. has said that in order to stay below the 1.5 Celsius level, emissions must fall at least 7.6 percent each year through 2030.
The new study calls for immediate improvements in farming practices, as well as changes in what we eat and how much food we waste to help reach the Paris Agreement goals.

When I was a child, I hoped to live in the city.I think I would be happy there.Now I am living in a city，but I miss my home in countryside.There the air is clean or the mountains are green.Unfortunately, on the development of industrialization, the environment has been polluted.Lots of studies have been shown that global warming has already become a very seriously problem.The airs we breathe in is getting dirtier and dirtier.Much rare animals are dying out.We must found ways to protect your environment.If we fail to do so,we'll live to regret it.

6 . Drive through any suburb in the U.S. Today, and it’s hard to miss the recycling bins that have become companions to America’s trash cans. Recycling has become common, as people recognize the need to care for the environment. Yet most people’s recycling consciousness extends only as far as paper, bottles, and cans. People seldom find themselves facing the growing problem of e-waste.
E-waste rapidly increases as the techno- fashionable frequently upgrade to the most advanced devices, and the majority of them end up in landfills (垃圾填埋地). Some people who track such waste say that users throw away nearly 2 million tons of TVs, VCRs, computers, cell phones, and other electronics every year. Unless we can find a safe replacement, this e-waste may get into the ground and poison the water with dangerous toxins (毒素), such as lead, mercury, and arsenic. Burning the waste also dangerously contaminates the air.
However, e-waste often contains reusable silver, gold, and other electrical materials. Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals, which can destroy ecosystems.
A growing number of states have adopted laws to ban dumping e-waste. Still, less than a quarter of this waste will reach lawful recycling programs. Some companies advertising safe disposal in fact merely ship the waste to some developing countries, where it still ends up in landfills. These organizations prevent progress by unsafely disposing of waste in an out- of- sight, out- of- mind location.
However, the small but growing number of cities and corporations that do handle e- waste responsibly represents progress toward making the world a cleaner, better place for us all.
