1 . Now a group of Italians have created the world’s first underwater garden for terrestrial plants. Called Nemo’s Garden, the project was launched by the Ocean Reef Group as a means to experiment with food supply diversity, should climatic changes make parts of Italy too dry to farm. The large self-sustaining, totally-contained biospheres would in theory be scalable, and perhaps in the future might look like the underwater city from Star Wars: The Phantom Menace.
The challenge existing in growing plants underwater, given that they are normally at home in soil, was but one obstacle Nemo has had to overcome. The six air-filled greenhouses suffered major storm damage in October 2019, and before they could be fully repaired, COVID-19(新冠病毒) had all the researchers sheltering in place.
Yet the team never gave up hope, as Euronews reports, and the months of abandonment did not harm the facility in any way. June 6th saw the garden fully-operational again, including their live stream where one can watch the plants grow. The biospheres(生物圏), which sit eight meters under the surface off the coast of Noli in Liguria, use solar energy for their minimal electrical needs, and evaporated seawater condenses(凝结) on the glass of the ceiling which waters the plants. A diver swims under and up into the air pocket of the pod to harvest what’s ready to eat.
The project website says that increased pressure like that found under the ocean is actually beneficial to the speed at which plants can come up, though they admit very little research has been published on the topic—after all, not so many people are currently trying to grow strawberries it underwater.
The conditions create a really intense flavor in the vegetables, and also allow the plants’ environment to be completely controlled, with nothing impacting their life dial the growers don’t want. For now Nemo’s Garden is essentially a research lab, but if tie idea were expanded, it’s expected to be able to keep food security for the peninsula, and the world.
