1. production of sustainable protein from the ocean,
2. maintaining mangrove habitats,
3. increasing offshore wind production and
4. decarbonizing international shipping.

As the global population grows, investing in wild fisheries would help provide healthy diets for people over the next 30 years while replacing carbon emission-intensive land-based proteins like beef and lamb, researchers contended. Every $1 invested in increasing production of sustainably sourced ocean-based protein is estimated to generate $10 in benefits, the report said.
