During the biblical time of Moses... as they wander thru the wilderness...God gave them Manna to eat an algae that grows on the rocks...
In this modern time... Scientist found species of blue green algae (spirulina) as the most nutritious food on earth... it is use as food for the astronauts by NASA... recommeded by UNICEF to feed the malnourish children...
And surprisingly the plant orginated some 3,500 years ago...
Hmm... comment pls... can it help human nature to continue to exist in this polluted world? When life expectancy is too short?
