ORIGINAL: Termyn8or "End large scale deforestation, leave old forests untouched, plant new ones. " While I am all for that, 70 % of the O2 comes from the oceans. A step in the right direction, but only a drop in the bucket. Also, what they should figure out how to do is irrigate the deserts and make them arable. Hey, they could use water from the ocean. ... A step, indeed, and just one step of more steps needed. A step still needing to be taken. Irrigating deserts with salt water only turns a desert into a salt desert. Inhabitable, any soil spoilt with salt forever. Like the great salt lake in Utah, the Turkana basin in E Africa, the Atacama in S America. For irrigating deserts you need fresh water - where there is none. Btw this is what Gaddafi did with Lybian petro dollars by hi-tech based pumping deep water resources (almost) dry. There were new green areas in the Sahara. But when pumping stopped either because there was no more water coming or after Gaddafi got killed, dry desert came back within months. Fossile water resources wasted, short term effect. So under present condition it is no good idea. "Salt water irrigation", however, is likely to happen with all our present low shore regions on a global scale if sea level rises like it does. Solid habitable ground lost and gone is more likely than new ground made available.
