Israel tried that - Gaza was left to the Palestinians.
You could complain about colonies in the West bank but not in gaza. No Israelis colonies were made there but hamas still wants to completely eradicate Jews from the neighbouring land.
A cow also produces a lot of methane, a much worse greenhouse gas.
Besides, the problem isn't the grass from cows grazing, it's the rainforests that go down all around the world to convert to farmland to produce animal feed.
It's much more efficient to use that farmland to feed humans than to feed cows and then feed humans (1kg of meat needs 25kg of feed)
Disclaimer - I'm not vegan but I try to reduce my meat consumption overall, especially red meats.
Não tenho a adicionar mas já vi alguns que tinham mt bom aspeto. Guardado!
Shot anyone trying to leave but plenty of Palestinians worked in Israel... Does not compute. Even if that were true, when your neighbouring country indoctrinates it's citizens to destroy the jews from an early age, you can't really trust any civilian.
Open air prison - then every country is an open air prison if you can't freely leave to neighbouring countries - It's called borders.
Dropped bombs? You might be confusing Israel with Gaza. Israel is the one that had to install an "iron dome" missile defense system due to random bombing from Gaza.
The brainwashing is strong here.
