For a while now, California has been witnessing a thick blanket of smog. And now scientists have found the main reason behind it – air pollution in China. Yes, you read that right! Apparently, pollution doesn’t need a visa to travel from one country to another.
A new report has found that pollution is traveling around the world and, in particular, moving from China to California.
“Scientists found Asian air pollution contributed as much as 65 percent of an increase in Western ozone in recent years,” NPR reported. “China and India, where many consumer products are manufactured, are the worst offenders.” A number of studies have come to similar conclusions, with one study finding “29% of particulates in the San Francisco area came from coal power plants in China.”
