Richard Hollingham talks to researchers at Plymouth Marine Laboratory about the role of marine algae in atmospheric cooling.
The scientist and author James Lovelock first proposed his Gaia hypothesis in the early 1970s.
The hypothesis suggests that the Earth regulates its environment to make it more suitable for life.

Marine scientists Steve Archer and Mark Breckels have been investigating how tiny marine algae produce gases that are involved in cloud formation.
They think this may help stop the Earth from overheating, providing an interesting link to Lovelock's ideas.
