LME-based conservation is based on recognition that the world's coastal ocean waters are degraded by unsustainable fishing practices, habitat degradation, eutrophication, toxic pollution, aerosol contamination, and emerging diseases, and that positive actions to mitigate these threats require coordinated actions by governments and civil society ...
The biggest threat of ocean plastic pollution comes from microplastics. These are small fragments of plastic debris, some of which were produced to be this small such as microbeads. Other microplastics come from the weathering of larger plastic waste. Once larger pieces of plastic waste enter the ocean, or any waterway, the sunlight exposure ...
The Mesoamerican Barrier Reef System is considered critically endangered according to the IUCN Red List of Ecosystems.

The previous record from the 2014 to 2017 mass bleaching affected just below 66% of the world’s reef area. Triggered by heat stress in warm oceans, coral bleaching occurs when corals expel the ...
The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. [7] This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. [8] It supports a wide diversity of life and was selected as a World Heritage Site in 1981.
Environmental groups said the agreement was a crucial part of efforts to meet a goal enshrined in last year's global biodiversity accord to protect at least 30% of the world's land and seas by ...
