Large amounts of corn and soybeans, amongst other resources, are needed to sustain the demand for proteins. Corn and soybeans are used to produce animal feed. Scientists have discovered a potentially more efficient source of animal feed – algae.
Algae can be cultivated in human-made ponds on otherwise unusable desert land, requiring only sunlight and seawater to grow. It’s about 30 times more productive than soy, and 50 times more productive than corn. It requires only 1 percent as much fresh water. It also has a much higher protein content — up to 70 percent, compared with about 10 percent in corn and 40 percent in soy. Replacing at least some corn- and soybean-based livestock feed with algae-derived feed would not only shrink the life-cycle impact of meat, it could free up a lot of land currently devoted to the production of animal feed, making more of it available for crops that directly feed humans instead.
Research into algae is not a new area. For almost two decades the U.S. government funded research into algae’s potential as a biofuel. The program was discontinued after concluding that algal biofuels could not be cost-competitive with fossil fuels. But oil prices have risen so much since then that algae has received renewed attention from investors as a potential fuel source.
In addition to protein, algae contains omega-3 fatty acids. Algae is actually the source of omega-3s. Fish don’t make omega-3s, little fish eat crustaceans that eat algae.
Research is still undergoing. There is hope for our planet.
