Sigh.
We could go slowly with that (kurzgesagt is good at balanced vulgarization).
Or we could go with recent assesments.

But it's pointless, isn't it. It's just a matter of sides, for you. Just like for gun violence, where you and your gang have decided that, by definition, any solution involving gun control would be (absolutely has to be) pointless, it's simply : You like beef, therefore beef is not an issue. Libs criticize beef overproduction, therefore beef is not an issue. From the conclusion up.
But no matter how baffling it is for the conservative mindset, there are people who like meat (who may even prefer meat over other food components), and YET, OMG, have the honesty to face the related issues. Some people accept that sometimes scientific realities don't go the most convenient way. Not everybody filter out realities based on personal comfort or profit.
But yeah, enough people do for this planet to be utterly fucked. And it's all the more pathetic to behold that those who do, those who profit from denial, those who have motives to cheat with reality, seek motives to attribute to others. Profit and short-term comfort is blatantly on the side of pollution and careless consumption, so reservations and scientific warnings must be driven by... hmmm... foreign-driven sabotage, self-loathing, anti-profit spite, agendas-for-the-sake-of-agendas...
Anyway, there are many forumers in here that are way more patient than me in front of collectively-cemented, self-serving, partisan bad faith. They probably believe that it can be overcome with data and arguments. That's not how it works. As long as there's something to gain in ignorance and denial, the subculture of navel-gazing will dismiss any global perspective. Yeah, go you. All is fine. Don't let the spoilsports rain on your parade(s). They are just meanies who detest freedom and happiness.
