Seaweed may help fight global warming Published: 16 May, 2005
SEAWEED may be the answer to fighting global warming, a group of Japanese scientists have claimed. The team envisages 100 vast nets full of quick-growing seaweed, each measuring six miles by six miles, floating off the northeast coast of Japan.
The seaweed in each net, will absorb prodigious quantities of greenhouse gases and convert them to oxygen before being harvested 12 months later as a rich source of biomass energy. If a pilot version of the project indicates that the idea is viable, and sufficient funding can be found, the concept of fighting global warming through giant seaweed farms across the world’s oceans could be included in the upcoming revision to the Kyoto Protocol. The project is led by Masahiro Notoya, a world expert on seaweed from the Tokyo University of Marine Science and Technology. Dr Notoya believes that Sostera marina and sargassum, herded to the right parts of the ocean, will grow up to 40ft every year, absorbing about 36 tonnes of carbon dioxide in the process.
