RESTORATION OF MARINE BIODIVERSITY

Reverse the decline of marine biodiversity in the oceans.

The following four recommendations can help to reverse major measures to reverse the decline of marine biodiversity in the ocean.

By reintroducing key marine species

If maritime environments can be effectively repopulated with key marine species, ecosystems may be able to recover from the harm caused by industrial activity, such as gas pipeline building or mining and marine biodiversity can be restored.

By stopping new invasive species

The introduction of new invasive species that are capable of taking over ecosystems poses a threat to existing ecosystems. Newcomers often have defence mechanisms or other features that allow them to outperform native species when it comes to getting food and other resources. Consequently, these types of new species can affect the marine biodiversity and we need to find a way to stop them around interacting with native species.

By addressing pollution and overfishing

All types of contamination must be eliminated, from excessive nutrient inputs to persistent organic contaminants and plastics. Furthermore, we must harvest responsibly, limiting harvests to help rebuild fish stocks, and combat illicit and unreported fishing. Improved regulation and enforcement, as well as proper stewardship of high-seas fish stocks, are required. Besides, due to the advancements in satellite technology and artificial intelligence, monitoring operations at sea is no longer reliant on self-reporting by fishing vessels.

By increasing carbon storage

Restoring marine life diversity requires growing the ocean's living carbon pool, which also helps to mitigate climate change. The recovery of mangroves, salt-marshes and sea-grass meadows are particularly effective in restoring the marine biodiversity in the oceans.
