What about the O2 part of the photosynthesis process?
The concentration of CO2 in the atmosphere would be the same if there were no trees at all. Marine algae produce many times the amount of O2 that trees produce.
They are good at carbon sequestration, too. Even though their itty-bitty bodies die in a few days or weeks and they decompose quickly, there are so many of them that there is a constant rain of deceased plankton onto the ocean floor. Since much of the (non-water) dead weight of plankton is carbon, the constant rain of plankton to the sea floor is a huge carbon sink. In fact, they are so productive that some scientists believe they are better suited to carbon credits than terrestrial plants.
Perhaps a dozen years or so ago some marine biologists noted that the brilliantly clear tropical waters are often iron-limited. So they did an experiment of hauling low-grade iron ore out into the equatorial deep-water Pacific and scattered iron ore the way a farmer spreads manure on a pasture. Their interest (IIRC) was aquacultural -- raising pelagic fish. The result was an algal bloom visible from space. Now it only lasted as long as the iron ore stayed in the lighted portion of the water column, but it demonstrated that fertilizing the ocean is possible and produces immediate results on a large scale.
It could be done for dual-purposes: Pelagic fish farming and carbon sequestration.
The downside is it would make a planktonic mess of the crystal clear tropical water.
The biggest problems we are facing right now have to do with George Bush trying to bring more and more power into the executive branch and not go through Congress at all and that’s what I intend to reverse.
