Hardly anyone is going to care to be honest which is unfortunate. The way our culture is, unless we see immediate results, nothing will change. People could try... but they'll just give up because "I don't see anything different with the planet and I did so and so". They don't realize change takes time. The documentary even made a great example that one easy thing we could do that can make a difference is just change our diet and cut our consumption of beef.
I was so frustrated watching this and they showed various news anchor claiming climate change is a hoax. One person even saying if you believe this is the biggest problem you're "the dumbest son of a ***** on the planet"
It's honestly frightening.
