This year’s extreme heat is putting the world’s coral reefs under such severe stress that scientists fear widespread die-offs, endangering not only the richest ecosystems in the ocean but also fisheries that feed millions of people.

New designs for fish farms could keep them in the ocean and help restore damaged marine environments at the same time, says a biologist working on a five-year nationwide aquaculture project.

Marine biologists in New Brunswick and in B.C. are employing mussels, oysters, sea cucumbers, urchins and seaweed to dramatically increase the amount of food created by salmon farms, and they believe they can extract excess carbon and nitrogen pollution from the sea in the process.

Taking the aquaculture industry onto land could be a missed opportunity to do the Earth some good and help mitigate the impacts of global warming, according to Thierry Chopin, a marine biologist at the University of New Brunswick. Nitrogen from agricultural sources contributes to oxygen depletion in the world’s oceans, resulting in huge dead zones in which nothing can grow. Fixing and storing carbon is believed to be key to fighting global warming.

“We have to think of extractive species as having a cleansing function in the ecosystem,” Chopin explained.
