Marine biologist Chuck Fisher offered an unexpected idea for fighting world hunger.
"My idea is directly related to me the studied animals, but originally came to mind many years ago, a graduate student in my time, when I was studying corals."
"I must admit that for the realization of this idea is still far, so this is just a dream."
Corals on a coral reef are a symbiotic relationship of photosynthetic algae that live inside the coral. This greatly reduces the needs of these organisms in food, because they get the lion’s share of nutrients they need directly from sunlight, like green plants. The idea consists in implanting Fischer tiny unicellular photosynthetic algae under human skin.
In the end, this will lead to an even greater variety of colors the human race than can be seen today. But the most important thing is that these tiny symbionts are able to create most of us need food that will feed hungry people around the world.
And since people are warm-blooded, we can grow our food under the skin, even in winter, subject to availability of sunlight.
