Corn and soybeans, the most common feed plants for livestock, are massive water and nutrient hogs. Livestock, moreover, are massive food and water hogs themselves. Cutting the inputs needed by the livestock industry is a critical step if we want to sustainably reach the 9 or 10 billion population point. Which is why advances in using algae for animal feed are so nice to see. Even better if it’s a method to use byproducts from the biofuel production process!
