How about killing off 95% of the human population and making the other 5% sterile?
That would probably save the planet right there.
Granted, it's probably extreme...
We don't need to save the planet, we need to save ourselves from clickbait-y headlines... *ba-dum-tss*
In all seriousness we Americans really eat too much meat. I get that most people don't care about their carbon footprint or even necessarily heatwaves or wildfire smoke, but we eat so much animal products and processed crap it's slowly killing us.
