• Except that veganism and the like is dangerous and bad for your health. People were not designed to eat just plant food, we are not gorilla's, our gut is different, our teeth are different, our stomachs are different.
• Global warming is a hoax, CO2 is less of a greenhouse gas than water vapour. If water vapour is more of a greenhouse gas then CO2 wouldn't there be more and more clouds until the sun wouldn't reach us anymore?
• Plants need CO2, it is their food and hundreds and thousand of years ago there was way more CO2 but it was cooler? How can that be? Is it possible that it is all BS just to make us pay more tax? Make us sick by suggesting we should not eat meat? Only the elite can? Like in the middle ages?
• I've watched such documentaries and I'd agree that farming animals like that is bad. But there are too many people on the planet to just be hunting maybe... Maybe if we would just eat organ meat that would satifsfy our needs much more. Organ meat has the most important nutrients.

So it's not sad, it is the opposite, based on truth. You can relax. If you want to save the planet don't have kids. You'd be pushing them into veganism anyway and they'd be weak and death before you know it.
