Normally, I would just ignore so combative a response, but as others may be curious, we’ll spend a few moments here. First, to address the only seemingly real questions asked, here are some sources:
Don’t Call Me a Pessimist on Climate Change. I Am a Realist.
This chart shows just how much energy the US is wasting.
Yes, the Climate Crisis May Wipe out Six Billion People.

Now to the rest of this, I’ll just ignore the question of whether I’m advocating the slaughter of 5 billion people, since that is, at best, absurd.

This does provide a good opportunity to discuss the fact that every activist is perpetually bombarded with some version of this:

“This [insert challenge here] is really hard, how are you going to solve it?”

The premise being that unless someone have every answer they can’t point out that there’s something that needs fixing. It’s just a cheap deflection. Of course I don’t have the answer to every question. We need the work of the collective, not a messiah.

We Americans, which I think you may also be based on your phraseology, are so used to living in a non-democracy that the idea of cooperation for the good of all is foreign. To be sure, this list of ideas is unlikely to be fulfilled. So far the world has shown no real signs of moving to save ourselves.

Maybe we’ll act in time to save ourselves or maybe we won’t. We certainly won’t if we decide the challenges we face are insurmountable.

Should I have misinterpreted the tone of the response and the questions were all genuine, then here are a few other resources that may be of interest.
