Our greatest challenge is pulling soo many heads, out of soo many assess. I think once we figure that out, the rest will fall into place

How about peace? That might solve a multitude of problems

Islam.
Humanity has a fair chance of dealing with global warming, but Islamic world conquest will result in the end of civilization.

Ignorance

The big question seems to be why aren't we... humanity/nations doing more... doing anything really significant about climate change? Maybe in dark back rooms in private meetings, the power-that-be don't want to actually do anything... not yet. Not until a large portion of the population is gone.

Advancement

Politicians generally only look to the next election. Trump knows the coal mining and other industries which use fossil fuels are behind him, and the workers who are employed in these industries will re-elect him if he keeps his promise to trash all the green energy initiatives. I just hope all the other countries who have signed up to the Paris Climate Treaty keep to it, but we need the US on board too.

Civilization.

Not killing itself off

Technology.

Fidelity to objective reality. I.e. Good mental health.

Survival

plastic!

not being able to find common ground something will always come up that mkes us right and them wrong no matter who we are it always happens

As humans in many cultures in many time periods we have destroyed our environment, causing the need to abandon cities (like Anchor Watt, many Mayan and Aztec cities and other ancient cities all around the world).

We evolved to survive immediate dangters and to supply immediate needs, but it doesn't appear to be hard wired into us to take care of our environment, and now we are destroying our entire planet, not just a few random local environments. We have few and swindling place to move to left on this planet.
