Wow.
Okay, that makes me realize we think of time differently.
I look at 50yrs and 200yrs, in the grand scheme of the planet overall, as maybe one second removed from one another. No difference in time. People in 200yrs will not be us but the problems they face with 300' more of ocean, will be just as huge. I'd see this as a problem even if it were a longer timeframe than 200yrs.
