New research has uncovered a change in behaviour of deep-sea fragile pink sea urchins off the south coast of Vancouver Island that is linked to climate change impacts including the " Blob ," a marine heatwave that persisted in the Pacific Ocean off North America between 2013 to 2016.

A team of researchers at the University of Toronto have designed a solution to reduce the amount of microplastic fibres shed when washing synthetic fabrics. In a world swamped by fast fashion - an industry that produces a high-volume of cheaply made clothing at an  immense cost to the environment  - more than two thirds of clothes are now made of synthetic fabrics, such as nylon, polyester, acrylic and rayon.

Study finds they outperform connected wetlands in filtering pollutants Small, isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them.

The good news is that global population growth has slowed and won't in itself cause climate change, says UdeM demographics professor Alain Gagnon.
