Those cute little creatures shown in the video are represent what may be the future of carbon sequestration.

CARS is the acronym for Carbon Algae Recycling System, it’s a system under development in Canada to clean up tailing ponds and greenhouse gas emissions left by the Alberta Tar Sands project.

As the video shows, exhaust CO2 is pumped into algae-rich tailing ponds where it’s digested. The plumped-out algae, full of hydrocarbons and heavy metals, are harvested and turned into biofuels.
