Spirulina is extremely unknown and underrated in my opinion. Often times when I talk with people about the idea of eating algae they often refer to information they have heard about how it can be dangerous to eat algae. I believe it to be extremely beneficial to eat and it may be one of the things needed or most easily accessible to cure world hunger. It grows so fast and is 60% protein by weight! That's insane! The more people know of things like spirulina and chlorella the better. It really makes you wonder if it's actually necessary to kill animals to get protein when this stuff grows way faster and doesn't have to suffer for us to eat.
