A new study by an international group of scientists denounces the up-and-coming octopus farming industry as both detrimental to fragile marine ecosystems and unethical given their high intelligence. As countries like Japan announce they will start selling farmed octopus in 2020, researchers call on companies and governments to discontinue funding the new industry, claiming there is still an opportunity to prevent the same unethical and destructive mistakes that have already been made with land-based industrial farming. Currently, there are 550 marine and aquatic species farmed in nearly 200 countries.
