Deep Sea Mining

Researchers are sounding the alarm over plans to launch industrial-scale seabed mining for the first time in international waters later this year. A new report by scientists from the University of Exeter and Greenpeace Research Laboratories says that such activities pose a "significant risk to ocean ecosystems" and could result in "long-lasting and irreversible" consequences.

Of particular concern are the undersea noises mining would generate up to 24 hours a day and the potential harm they could bring to about 25 cetacean species, such as whales and dolphins. "Like many animals, cetaceans are already facing multiple stressors, including climate change," said Exeter's Kirsten Thompson.

Toxic Ice

An Oxford University-led study warns that Norwegian Arctic ice has become contaminated with “alarming levels” of toxic PFAS, or “forever chemicals” that do not break down naturally and have been linked to cancer, liver disease and other serious health problems.

The study says that when melted, the contaminated ice represents a major threat to the region’s wildlife. It adds the chemical cocktails could harm the entire food web, including plankton, fish, seals and polar bears. PFAS are a group of about 12,000 compounds used to make thousands of products, including those that resist water, stains and heat.
