What is it?
Algae are mainly aquatic-based plants, ranging in sizes from unicelluar microalgae to massive organisms that can grow up to 50 meters in length.
How could algae save the world?
Algae have many uses, depending on the specific species — food, organic fertilizer, biological filtration and sewage, but most importantly, biofuel.
With an incredibly fast growth rate and the ability to grow in shallow or salt water, it possible to produce algae-based fuel very quickly and on land that would be otherwise unsuitable for other crops.
“It is estimated that 15,000 square miles of algae production could supply the United States with all of its fuel needs – that’s about 1/7 of the land currently planted in corn in this country. Some algae fuel is already being sold and experts predict that by 2025 the technology will be refined to the point where the price per gallon will break even with the cost of petroleum.” Source
