Reading the news about how the oceans turned into"Urns" for plastic garbage, one would think that humanity has harmed every corner of the planet Earth. However, recently employees of the National Geographic Society found a place to which human hands still have not reached. We are talking about an underwater forest of brown algae, located on the outskirts of South America, near the Tierra del Fuego archipelago (Tierra del Fuego). Scientists studied this place back in 1973 and then among the densely growing algae lived sea urchins, stars and many different fish. Having dived into the underwater forest after almost 50 years, divers found that the local inhabitants feel great to this day. But how did algae and aquatic inhabitants survive during a time when the world is literally buried in piles of plastic garbage?
What are underwater forests?
About the perfectly preserved brown algae forestwas told in the scientific journal PLOS One. Such accumulations of algae are currently on the verge of extinction due to the effects of global warming, so the forest found in excellent condition can be considered a real miracle. Forests of algae are usually located near the sea coast, at a depth of 10-25 meters. Usually they grow algae from the orders of Laminariales, Macrocystis and Nereocystis, the length of which can reach 60 meters with a weight of up to 150 kilograms. All this vegetation attracts many marine animals, therefore algae forests are considered a favorite place for sea urchins, stars, crabs, mollusks and tubular worms.
Algae forest - underwater territories with a high density of algae growth at a depth of 10-25 meters.
A place untouched by man
According to scientists, the underwater forest remained intacteven after half a century because it is very distant from people. In addition, it is surrounded by a restless sea, which in theory can protect the place from plastic debris and other troubles. Thanks to these two factors, not only algae remained intact and unharmed, but also the fish and other marine inhabitants that lived among them. Perhaps the special location also reduced the harm from global warming, but more precisely, scientists will only learn about this in the framework of the following scientific works.
How to save nature?
Thanks to the discovery of pristine forestalgae, scientists could see with their own eyes how good life would be for marine inhabitants and algae if humanity did not pollute the environment. In further research, researchers want to find out what other factors helped algae and animals survive in such a difficult time. New knowledge will help environmentalists protect areas of our planet that are particularly affected by human exposure. Perhaps due to all this, they will be able to increase the lifespan of underwater forests by at least 50 years.

Today, much attention should be paid to forestsAmazons, because recently scientists have come to the conclusion that they can turn into a desert in a few decades. The greatest danger to forests, of course, is people. Not only is humankind actively cutting down forests for the manufacture of building materials, it also destroys it indirectly, throwing a huge amount of greenhouse gases into the air. Due to harmful emissions, a greenhouse effect arises on the planet, which gradually raises the air temperature and provokes the occurrence of terrible fires.
