Heard about Planktos and reducing CO2 that way?

Answer 1

Phytoplankton are microscopic marine plants, invisible to the naked eye but visible from space as blooms of green ocean. Like all plants they photosynthesise - taking in carbon dioxide and releasing oxygen. Increasing the quantity of phytoplankton will result in more carbon dioxide being absorbed and when the plants die they sink to the ocean floor taking the carbon with them. Professor Ian Jones of Sydney University advocates that by using nitrogen rich urea to enrich parts of the oceans low in phytoplankton their numbers can be significantly increased. One commercial organisation that advocates increasing plankton levels as a method of carbon-offsetting is called Planktos - http://www.planktos.com/

This is one of the ideas that formed part of a BBC documentary 'Five Ways To Save The World' you can read more about them on the BBC Website here http://news.bbc.co.uk/1/hi/programmes/6298507.stm watch the programme trailer here http://news.bbc.co.uk/player/nol/newsid_6360000/newsid_6364700/6364731.stm?bw=bb&mp=rm or watch the programme in full from Google Video here http://video.google.com/videoplay?docid=286000425078890061
