Coral reef ecosystems offer a variety of essential ecosystem services including shoreline protection, nitrogen fixation, and waste assimilation, and tourism opportunities. The continued decline of oxygen in oceans on coral reefs is concerning because it takes many years (decades) to repair and regrow corals. [82]
[14] [15] Coral reefs are microbially driven ecosystems that rely on marine microorganisms to retain and recycle nutrients in order to thrive in oligotrophic waters. However, these same microorganisms can also trigger feedback loops that intensify declines in coral reefs, with cascading effects across biogeochemical cycles and marine food webs ...
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Coral reefs are dying around the world. [147] Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [148] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.

The functions of the Act include: establishing enforcement officers and litter wardens who may issue fines and abatement notices for litter offences
The deterioration of coral reefs is mainly linked to human activities – 88% of reefs are threatened through various reasons as listed above, including excessive amounts of CO 2 (carbon dioxide) emissions. Oceans absorb approximately 1/3 of the CO 2 produced by humans, which has detrimental effects on the marine environment.
Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean.Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack.
