It won’t destroy farming, it will just encourage farmers to use their land for different purposes. We still need to eat fruit, vegetables, and grains.

The land use required to rear cattle is phenomenal, not to mention the carbon footprint associated with the animals. This is more than just “marketing”.

Yes, we need less cattle 100%, but this product is more like to be just taking another CEO for a fun ride to space, than «saving» the planet. Is important not to be naive. We need to go green but we need to make sure the green wave is really green. Not just more money for the rich guys.

What if those chemicals will depopulate some humans in the end saving the world?

Population isn’t the problem. Consumption is.

Yeah, the meme about the world being overpopulated really needs go away. Having fewer people doesn't mean "more for the rest of us" but fewer people doing useful work.

Morally I find the notion that the Earth is overpopulated to be evil. The problems we see from “overpopulation” is not too many humans, but instead artificial scarcity and a shortage in land.

Consequently I don’t believe the people who say space colonization won’t fix most of our issues.

Sounds great, so long as it’s not me or anyone I care about.

I should have worded that as "all humans" instead of "some humans"
