Ok, some facts since people are voicing what they know little about.
First off, the US is not the wild west, I live in the San Fernando Valley, home to probably a few million people. Seldom is there any gun violence here, you can check on

The only reason people think it's violent is because of bias opinion on the news
Justified shootings are if you can prove you believed your life was in danger or someone else's life was in danger in California.
Pretty easy to prove if you found someone in your house. Just make sure all shots were to the front of the trespasser and make sure they were dead so that the only statements came from you!
I see more conjecture from AKA thinking he knows anything about what goes on in the US, it's clear he doesn't live here and doesn't know jack shit but continues to spread it thick.

Carbon is not the problem, it makes up 0.041% of our atmosphere , 95% of that is from Volcanos and decomposing plants and stuff. So people in the US are responsible for 13% of the carbon in the atmosphere which 95% is not from Humans, like cars and trucks and stuff and they want to spend trillions to fix it while Solar Panel plants are powered by coal plants
think about that
