Halophytes: How To Solve The Land, Water, Food, Energy & Climate Emergency While Generating Wealth

Society is beset with human engendered climate and ecosystem issues, which are approaching existential. Solutions for such are sought, and from the experience with renewable energy development, such solutions are instituted far more readily if they are profitable. Halophytes - salt plants grown on cheap land (deserts and wastelands) using cheap water (saline, seawater) pumped by cheap photovoltaics - uniquely provides the requisite scale and effects to solve land, water, food, energy, and climate problems.

The use of Halophytes as a solution to climate and ecosystem issues brings into production vast new regions; some 44% of our land is deserts/wastelands. There are some 10,000 different Halophyte, which can grow massive amounts of food, release large amounts of the 70% of fresh water now used for agriculture to direct human use. We could literally green the planet and remove CO2 from the atmosphere since Halophytes sequester some 18% of their CO2 uptake. Halophytes are biomass, and can be used for green fuels and petrochemical feed stocks, obviating the need for petroleum based production of such. Overall, the business, climate, and ecosystem benefits are extraordinary. No new technology is required, impacts on climate and ecosystem are prompt and inexpensively obtained.
