Yes and yes.

But suicidal? I wouldn't use that term. My definition of suicide would include intent, and I think we're going to destroy ourselves, but we're not going to *intend* to.

By the way, our future is in jeopardy no matter what--the sun has a finite lifespan. When it goes, we go, unless we've managed existence independent of the Earth by then.

So, one thing to guarantee future survival, is "be able to continue to exist without the planet Earth around."

That's a long way off, though...

More immediately, we need to figure out, systematically, what kind of society the Earth can sustain indefinitely.

I also think we should back off on the fossil fuels, because they're finite, and we are using them REALLY quickly, and we might need them for an emergency someday. Plus, they *might* be causing bad climate change.
