They should just harvest a huge block of ice from a comet and drop it in the ocean.

Makes sense.
- Create a massive rocket
- Burn a massive amount of rocket fuel to get it into space
- Surround the comet ice in enough artificially made heat resistant materials so it doesn’t burn up in the atmosphere
- Use more rocket fuel to angle the giant ball of ice so it doesn’t burn up on re-entry
- Burn some more fuel to slow down its descent once inside the atmosphere so it doesn’t crash into the earth, ending all life in the immediate area
- Drop the ball of unsalted ice in the ocean
