B.C’s pink sea urchins are on the move to shallower waters thanks to climate change

Pink sea urchins off the coast of Vancouver Island are expanding into shallower waters, in what researchers say is an indication of how rapidly climate change is affecting ocean life. Researchers at Memorial University, Ocean Networks Canada and the University of Victoria found the urchins, living as deep as 400 metres below, were expanding their populations into shallower water at an average rate of 3.5 metres per year as ocean warming reduces oxygen levels and food sources at lower depths.

Study sheds light on human consumption of microplastics

Study sheds light on human consumption of microplastics

The study found that a person's average microplastic consumption — based on those food items previously analyzed — would likely be somewhere between 70,000 and 121,000 particles per year. While younger girls were at the lower end of the spectrum, adult men were at the high end. People who consume a lot of bottled water could see that number jump by up to 100,000 particles per year.
