desert re-forestation process

1. Starting from the coastline, use solar (or wave) energy to pump sea water inland and desalinate most of it.
2. Mix the fresh water with sea water to produce the concentration at which microalgae multiply at maximum rate.
3. Cultivate microalgae in shallow ponds of this ‘magic mix’.
4. Harvest microalgae and breakdown using anaerobic bacteria to produce methane gas and liquid/solid fertiliser.
5. Burn methane gas to produce carbon dioxide and water (vapour).
6. Fertilise and grow trees (or other vegetation) in inflatable-walled dome into which the carbon dioxide and water are pumped.
7. When trees are established, extend sea water piping, move dome further inland, and repeat.
