I have been thinking recently, if a climate crisis is almost inevitable at this point what actions could an individual take to stay safe? I'm thinking some kind of underground bunker able to to sustain life. The main things you would need is power, water and food. The power is fairly simple since you could set up solar and wind generation and probably use that to grow food underground but I'm wondering what you would do for water. How possible would it be to collect barrels from the sea and have a personal desalination plant.
