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
Hence, it can be done!

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.

GES4SEAS MOOCs @ges4seas-mooc.fediscience.org.ap.brid.gy · 6d

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

GES4SEAS MOOCs @ges4seas-mooc.fediscience.org.ap.brid.gy · 6d

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…
