Thanos' plan was so fucking stupid. He wanted to eliminate half of the population to reduce the lack of resources. This completely ignores how populations grow exponentially and will be back to the original quantity in a generation or two... His plan kills half the population while not actually fixing the resource problem.
Should have just snapped his fingers for unlimited resources. What a dum dum.
Fun fact, in this ship Sun zoo gathers 2 of each animal and beat the crap out of every single one of them and that's why anytime a bunch of animals are together in one place it's called a zoo!
