Quite a lot. In no particular order and not a complete list:
Climate change, pollution, late stage capitalism, resource depletion, overpopulation, obesity, post truth, propaganda, susceptibility to propaganda, education, lack thereof, lack of critical thinking, short-sightedness, lack of beneficial public discourse, taking action on problems, vested interests funding our demise, lack of hope, no continuity, lack of trust, crab mentality, etc.
Yes!
As stupid as it sounds people trust them more than the experts. We live in the post truth times anyway.
