Six Technologies That Could Shake the Food World
There is a shallow blue-green pool of water in the New Mexican desert, and it isn’t a mirage: It is a site for growing algae, plants rich in protein and Omega 3.
It is also a potential solution for a global food dilemma. The world is running out of land for raising animals for food, experts say. Algae grow well in brackish water and in the desert because of the abundant sunshine and the fact that they don’t need fresh water—potentially bringing more unused land into productive use.
Now advances in algae farming are making it a popular ingredient in new foods like algae-based protein bars and vegan shrimp, as well as other products such as fish feed and food coloring.
