Microalgae biofuels may provide a viable alternative to fossil fuels. Algae efficiently use CO2 and can produce biomass very quickly. Some species can double their mass in as little as 6 hours. Such single-celled organisms are amenable to high-throughput techniques to evolve new strains, unlike terrestrial biomass sources like corn which can take years to modify.

The Great Salt Lake Is Shrinking
Utah’s Great Salt Lake is the largest salt water lake in the Western Hemisphere and is the largest body of water in the United States after the five Great Lakes. When the pioneers first arrived in the area back in the middle of the 19th century, the lake spread across about 1,600 square miles. Now, the lake covers an area of only about 1,050 square miles, a reduction of about 35%.
