An article here a couple of weeks ago claimed that sea weed is more effective than tree fighting carbon dioxide, and it seems cheaper to plant and manage... Shouldn't we focus on it instead of trees ?
I wonder which would be more effective at countering ocean acidification, since sea plants need the carbon dioxide in the water in order to create oxygen.
While I've been a bit skeptical on global warming, if we decide carbon in the atmosphere needs to be dealt with then we should probably put a price per ton on it and deal with it by whichever methods are cheapest. I'm supposedly financing the removal many tons by donating to Trees for the Future and it's crazy cheap. Something like $100 for 50 tons per year. And that's for the life of the trees so something like 10c/ton.
