90% of Table Salt Is Contaminated With Microplastics
By Julia Conley
A year after researchers at a New York university discovered microplastics present in sea salt thanks to widespread plastic pollution, researchers in South Korea set out to find out how pervasive the problem is—and found that 90 percent of salt brands commonly used in homes around the world contain the tiny pieces of plastic.
The new research, published in the journal Environmental Science & Technology, suggests that the average adult ingests about 2,000 microplastics per year due to the presence of plastics in the world's oceans and lakes.
Examining 39 brands sold in 21 countries, researchers at Incheon National University and Greenpeace East Asia found microplastics in 36 of them. The three table salts that did not contain the substance were sold in France, Taiwan and China—but Asia overall was the site of some of the worst plastic pollution.
The study "shows us that microplastics are ubiquitous," Sherri Mason, who conducted last year's salt study at the State University of New York at Fredonia, told National Geographic. "It's not a matter of if you are buying sea salt in England, you are safe."
Greenpeace East Asia found a strong link between the level of plastic pollution in a given part of the world and the amount of microplastics people in those regions are inadvertently ingesting each year.
"The findings suggest that human ingestion of microplastics via marine products is strongly related to emissions in a given region," Seung-Kyu Kim, a co-author of the study, told National Geographic.
Nat Geo Travel put it succinctly on Twitter:
Indonesia, it was found in an unrelated 2015 study, has the world's second-highest level of plastic pollution. The researchers in South Korea discovered that the country's table salt brands also contain the most microplastics.
"That fact that they found higher counts in Asia is interesting. While not surprising, you still have to have the data," Mason said. "The earlier studies found traces of microplastics in salt products sold in those countries, but we haven't known how much."
Erik Solheim, the executive director of the United Nations Environmental Program, called the study "more evidence of the frightening proliferation of plastic pollution"—and expressed hope that studies like this one would encourage more governments and companies around the world to sharply reduce their use of plastics.

Plastic pollution in the world's oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.
Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.
"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"
Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.
The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.
Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.
Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Organizers said 35,000 people marched through the streets of the German capital on Saturday to say they're "fed up" with industrial agriculture and call for a transformation to a system that instead supports the welfare of the environment, animals and rural farmers.

If you have ever considered making the switch to an environmentally friendly electric vehicle, don't drag your feet. Though EV prices are falling, and states are unveiling more and more public charging stations and plug-in-ready parking spots, the federal government is doing everything it can to slam the brakes on our progress away from gas-burning internal combustion engines. President Trump, likely pressured by his allies in the fossil fuel industry, has threatened to end the federal tax credits that have already helped put hundreds of thousands of EVs on the road—a move bound to harm not only our environment but our economy, too. After all, the manufacturing and sale of EVs, hybrids, and plug-in hybrids supported 197,000 jobs in 2017, according to the most recent U.S. Energy and Employment Report.

Formidable predators stalk the forests between Panama and northern Argentina. They are sometimes heard but never seen. They are small but feisty and have even been documented trying to take down a tapir, which can top out at nearly 400 pounds. Chupacabras? No.
