I have these two sentences stuck in my head these days:

A French minister: we need to prepare ourselves for a future when temperatures are 4°C higher.

A climate scientist: with a rise of 4°C above pre-industrial age, up to 90% of the world's population may die.

(edit: muting the post, it's going way beyond its intended audience, I'd like to be able to see notifications about other things. thanks you all for sharing)

@David That's assuming 90% of the population sit idly by while the coastline moves inland. That won't happen

@CubeRootOfTrue @David

There is always the possibility to move underground too. Life will always find a path (not saying this is a path I want though :S)

@Beldarak @David people talk about habitats in orbit with nuclear power for growing plants, we should probably test this here, underground

@CubeRootOfTrue According to https://permaculturism.com/how-much-land-does-it-take-to-feed-one-person/

To feed 1 person for a year with veg, fruit, eggs, chicken, milk, wheat & grain you need ~2 acres of land

I was taught you also need a fallow field & you rotate this field each year

So say ~3 acres with ⅓ unused a year

You could use a shelving system to reduce the total footprint but that's still a fair amount of space & that's just 1 person with simple tastes doing all the work

No way is a billionaire doing that

@staringatclouds @CubeRootOfTrue @Beldarak @David it can be less if you remove farm animals from the equation.
If the world adopted a plant-based diet, we would reduce global agricultural land use from 4 to 1 billion hectares

We could reduce the amount of land used for grazing and croplands used to grow animal feed.

Our World in Data
@bhasic @alemarcati @staringatclouds @Beldarak @David I see that data and think, if we did that, the population would quadruple
@CubeRootOfTrue @bhasic @staringatclouds @Beldarak @David I don't think so. It's not like it's lack of food that is the bottleneck preventing population to grow
@CubeRootOfTrue @bhasic @alemarcati @staringatclouds @Beldarak @David would it? And even if it did, how long would it take?
@bhasic @alemarcati @CubeRootOfTrue @Beldarak @David And if we switched to eating yeast grown in vats we could probably use a fraction of that
@staringatclouds what do you think yeast grows on?
@temptoetiam Oh dead bodies, plant matter, any sugar it can find

@bhasic @alemarcati @staringatclouds @CubeRootOfTrue @Beldarak @David

And modified home-brew EarthBox-style growing systems can give increased crop yields, with 3 harvests-per-year growing outddors, and 4-5 harvests-per-year indoors.

Used globally, at current temperatures, they could increase growable land by ~40%.
