Tech: Seaweed as a carbon dioxide sink

[dracodraconis]

A group of scientists have proposed that seaweed could be a viable method for sequestering carbon dioxide from the atmosphere. Seaweed's rapid growth means that it could use up as much carbon dioxide as a rainforest while providing an alternative source of food and fuel. Currently, more than 8 million tons of seaweed and algae are harvested for food, almost exclusively in Asia-Pacific region.
