Resources of the Ocean (some nonrenewable* ~ cannot be replaced within 1-2 generations)
Raw Materials

other raw materials* ~ (steel, copper, nickel, cobalt, phosphates)
tidal & wave energy (clean & renewable)

kelp used to thicken ice cream (seaweed is a type of alga)
Food ~ fish, shellfish, some seaweeds/alga
