Scientists have been developing “Nemo’s Garden” off the coast of Italy for the past 4 years. These special greenhouses are designed to grow fruits and vegetable under the water and it could change the way we farm in the future.
At 20 feet, the gardens are shallow enough for sunlight to reach the plants and deep enough for the temperature to remain a steady 79 degrees day or night.
It seems like a pretty farfetched idea but this system provides an infinite source of water and protection from insects. Water from the ocean evaporates inside the biospheres and is used to water the plants.
The project is a long way from being able to solve the world’s hunger/water issues but who knows, maybe someday these biospheres will be commonplace.
