@farbel As for vision, my suggestion would be to have a look at what's going on with #solarpunk , however their scope is wider.

As for me, I am interested in our money system and it's impact and also in complementary and alternative money systems and their possibilities, maybe also for housing.

As for housing, I would not be surprised if we would come to live in self-supporting communities, rather then in cities.
Investers will then of course have already sold their empty houses 🤭

You know, I'm thinking you're right about that, @fdriesenaar . "As for housing, I would not be surprised if we would come to live in self-supporting communities, rather then in cities."

@DoomsdaysCW @fdriesenaar If we spread 10 billion people across the planet in small communities, where is the food grown? There is less than half an acre of arable land per person on the planet.

Good point. Obviously, those communities would have to have some population density. But perhaps those *cities* wouldn't be "concrete monstrocities," but places were folks would grow their own food -- balcony gardens, rooftop gardens, indoor greenhouses, food forests, etc. @farbel .

@DoomsdaysCW @fdriesenaar I might posit that cities as they exist now could be self-sustaining, with vertical agriculture and rooftoop gardens.

@farbel
I hope that you don't mind me adding to the thread. I wrote about this recently and I think your .5 acre assumption is more constraining than reality.

There are three reasons to be more optimistic I think:

1. there's more agricultural land than arable land, which we can use much more effciently (˜x5),
2. there's a lot of surfaces we can use (>x2)
3. a hectare is two acres (x2)

Please correct me if I'm wrong!

@farbel
that brings us to a sustiainable ~80 billion #solarpunk vegans or so.

Then if we really go sci-fi, we could use the oceans for floating farms and add another 200M km² of useful surface to the mix before we need any investments to go to mars.

over 250 billion people could have a decent meal on this wonderful planet before we need to worry about overpopulation really.

@DoomsdaysCW @fdriesenaar

I'm not sure if everyone can/should be vegan -- but anyone who isn't should at least cut down drastically on their meat consumption. Make it a special occasion, not an everyday occurrence. @iwein @farbel @fdriesenaar
@DoomsdaysCW
2 meat based meals per day is in fact too much for one's health. One every other day is enough without having to brain about it. I guess meat once a day isn't too bad for the planet.
@iwein @farbel @fdriesenaar
Hubby and I make meaty dishes (which includes fish) maybe a few times a month, and usually incorporate it as part of the main dish, not the main course. Now, dairy, on the other hand... Which is why I've been switching to goat-based dairy instead of cow-based. @ScriptFanix @iwein @farbel @fdriesenaar

@DoomsdaysCW
Goat and ewe dairy products are in fact healthier, cow milk is way too fatty for us big monkeys. My fiancée converted me to goat and ewe cheese yogurt, rice milk for cooking, meat or fish once a day.

And I'm all for switching to insects as a main source of proteins! That's also way more sustainable: warm-blooded beings waste tons of energy
@iwein @farbel @fdriesenaar

I wonder how buffalo milk fares, @ScriptFanix. And I haven't tried goat yogurt (or cottage cheese) yet (I might even try making my own). Also, as for our meaty meals, those usually last a few days (leftovers). The rest of the time, I eat frozen leftovers like veggie lasagnas or soups, and also make up a veggie-laden pizza once a week (two meals for me). Hubby likes store-bought Pad Thai and other quick vegetarian meals (I'd rather eat frozen leftovers, which I often do).
@ScriptFanix Also, I discovered insect-eating accidentally. I bit into a chocolate cupcake that was loaded with ants, and didn't mind the taste (though the squirminess was a bit unnerving. Still is. I prefer my grubs roasted.)

@DoomsdaysCW @ScriptFanix

Love your posts :)

I have a 6 person house hold we eat meat about 2 times a week, fish once, but meat mainly for the children, still growing. Cheese and yoghurt are eaten daily, so I think there is room for reducing our footprint there.
Thanks for your reminding me and your tips :)
