re: #6 LudwigVanQuixote

Actually this has been a major concern in the literature for some time. It is only recently that the MSM has picked up on how much very serious damage to the seas we are doing.

There are very many bad effects to this. Changes in salinity also change currents. The shut down of thermohaline conveyors will have drastic effects on many species, including land life - including us - by shifting global weather patterns.

Another giant issue is acidification of the oceans and resulting ocean anoxia. What people fail to recognize is that ocean anoxia means not enough oxygen in the oceans to support no photosynthsizers and that ocean acidity kills photosythesizers. We are literally talking about processes that will wipe out many species in the oceans - things that we like and depend on and could eventually lead to no life larger than microbes in most parts of the sea.

People need to understand not that the ecosphere is fragile, but rather, even though it is hard to break, we are breaking it right now and that once it is broken it will take millions of years to fix.
