Scientists propose to restore aquatic ecosystems through aggressive varieties.
The active intervention of the aquatic plants helps to fight climate change. To such conclusion scientists from the Smithsonian environmental research center. They noticed that some invasive species (unusual for ecosystems and planted by people) actively absorb so-called “blue carbon”.
The so-called carbon stored in the hydrosphere: riparian vegetation in estuaries, wetlands, freshwater bodies, shelves, and also inhabitants of the deep waters. Hydrosphere has a huge potential to absorb greenhouse gases. Marine ecosystems to absorb emissions to 40 times faster than forests, but they disappear quickly. Every year the planet loses about 8000 sq. km.
Scientists from the Smithsonian environmental center did a meta-analysis based on data from 104 studies. They compared the potential of various aquatic ecosystems to absorb greenhouse gases.

Ecologists found that in those systems where listed species consisted in the remote relationship with the species-endemic species, total biomass increased by 120%. Thus, these varieties have shown themselves to be real engineers of the ecosystem.
“They not only help to build and restore habitat, they do it more aggressively and effectively,” says ecologist grace Gott.
Scientists cited the example of a new species, mangrove, introduced to the depleted mangrove forest and the reeds planted in the salt marsh. In comparison with native species, the invaders grew faster and became larger and faster absorbed “blue carbon”.
“To try to mitigate the effects of climate change, we need ecosystems to be carbon, says grace Gott. If some invasive species increase the potential, that’s a plus. As exhausted and destroyed coastal ecosystems give the accumulated carbon back into the atmosphere. We do not encourage to stick all these aggressive types. But it is important that the water environment has not been destroyed.”
