>Is it self-sustainable if food/entertainment isn't included? I say yes, because as humans we enjoy a diverse range of food than our own ecosystem anyways. So I don't think importing food is a bad thing.
This is not sustainable. Setting up an island that constantly has to have food and people shipped in and people and trash shipped out is going to be a loss sustainability-wise compared to just living mainland and using renewables there.
