I have found that Vodka martinis mitigate the sadness for a short time.

Yeah, today's profits seem to over rule the likely events of world conditions changing to where human extinction is becoming more and more probable..

The earth can take a lot, and will continue to change as it ages. If we aren't around to see it happen, well, no biggie. EVERYTHING becomes extinct at some point.

We are beyond the point of no-return for how we live today. The tundra is melting. The glaciers are melting. The ice caps are melting.

Humanity will survive. And the planet will repopulate what we have destroyed. Sad for all those who will live through the next 100 years.

Long term the planet cannot sustain the food supply with the population growth. The oceans are over-fished, the chemicals you mentioned have allowed for production to meet current demand, but have come at a cost. In my opinion food will be quite different in the future. Artificial meat, greater consumption of insects, are all options-but the status quo won't be.
