okay, so here's the deal. The planet is getting warmer, and it's at an irreversible point now. Whether we caused it with pollution or not is up for debate, but personally I agree with the world-wide scientific community that pollution caused global warming. Unless we do something very drastic and very expensive that can somehow make the planet colder in the polar regions, we are going to have a lot more water and a lot less land in the next 100 years or so.
I am not opposed to ocean life. In fact, I want to live on one of those floating cities right now. or in a sealab 2020(1) kind of thing. As long as these floating cities are indeed self-sufficient energy-wise, and completely powered by renewable energy and does create pollution in my water, then i am happy with them.
However
We need to have colonies in space more than anything. Stephen Hawking said so.
