#recovery rates across studies suggest that substantial recovery of the #abundance, structure and #function of marine life could be achieved by 2050, if major pressures, including #climatechange, are mitigated

Rebuilding marine life - Nature
Analyses of the recovery of marine populations, habitats and ecosystems following past conservation interventions indicate that substantial recovery of the abundance, structure and function of marine life could be achieved by 2050 if major pressures, including climate change, are mitigated.

The most important reasons for this reversal in seagrass abundance are, #management measures, including habitat #restoration, seagrass transplant, #eutrophication reduction, among several others

Since then, loss rates slowed down for most species and fast-growing species recovered in some locations
This resulted in a net rate of change in #seagrass area, experiencing a reversal in the 2000s, in Europe

After some research, from 1869 to 2016, one third of European #seagrass area was lost due to disease, deteriorated water quality, and coastal development
The highest decline was the 1970s and 1980s

Recent trend reversal for declining European seagrass meadows - Nature Communications
Seagrass meadows are important but one of the most threatened ecosystems globally. Here the authors analyse data about extent and density of seagrasses in Europe from 1869 to 2016, and find evidence of recent trend reversal for declining European seagrass meadows.

The High Seas Treaty is legally binding for the 81 nations that have ratified it
They agree to put it into effect at the national level
However, several major economies have not yet ratified it, such as the US, India, UK or Russia
This could be a problem, by there is hope

here you can see what are considered as high seas (dark blue)
These high seas regions make up over two-thirds of the #ocean's surface, representing over 90 % of the earth's habitat by volume.
Until now, these areas were not protected, and everyone could exploit them without limit.
However, from now…

In California, sea otters were once thought to be extinct but an isolated population of about 50 was found in 1914.
Subsequently protected by laws and treaties, they have slowly recovered, as shown in this graphic from @usgs-quakebot.bsky.social
