When I wrote recently about the carbon credit industry I tried to make the distinction between good bad carbon credits. Today wired.com has a story about an Australian company that is planning on dumping urea into the ocean. This urea, (which is very high in nitrogen), is supposed to feed algae & plankton in the area, which in turn will use carbon dioxide from the air. When this algae & plankton dies, so the theory goes, it will sink to the bottom of the ocean, taking the carbon with it.
A plan like this screams for regulation. Does dumping nitrogen into the ocean really sound like a good idea? We’ve been told for years not to use soap or fertilizers with too much nitrogen in it because it unbalances the ecosystem of the bodies of water where the runoff ends up.
Not only does this plan pollute in ways that we’ve been trying to avoid for years, but it is also next to impossible to measure how much carbon will be sequestered, (if any), by this project.
That’s about all I have to say, read the article yourself and form your own opinions.
