My reasoning is that you cannot save the environment by regulating and degrading human life. It's like claiming that you will cure someone by killing him, technically correct... but the kind of correct that works on a weird leftist brain only.
The upper class are living lives so lavish, the emperors of Rome could have never dreamed off. We should change companies like Nestle, every single non-European company, data center companies, etc. from destroying our environment for profits. We should regulate the usage of jets and airplanes (for everyone, not just poor/middle class). What we should not do is say stupid stuff like cow-farts are destroying the environment and you need to eat bugs, or forced through digital currencies and social credit systems to only be able to go wherever the government tells you you can go. This is not even remotely near the realm of 'conspiracy theory', it's a reality for china/russia, and seriously studied by the EU, and even tentatively tried in the UK.
I actually was curious about his reasoning though.
