"The real reason everything is happening is there’s too many people.."

Bingo. I believe that excessive human population is the root cause of many global problems.

But what defines a "Star Trek Future" in the context of this question? The level of technology? The utopic society and healthy human relationships? Or just simply becoming a space-faring species?

I believe, and not necessarily because of environmental issues, that the species has much less than half of a millennia to be dominant, and much less than 100 years of the modicum of stability that we have had from 1946 to 2000. Gen Z may never know 'stability' in either society or economy.
