Coral reefs are dying around the world. [1] Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [2] 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.
Coral reefs are among the more productive and diverse ecosystems on the planet, but one-fifth of them have been lost in recent years due to anthropogenic disturbances. [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.
A major concern for marine biologists is the collapse of coral reef ecosystems. [40]). An effect of global climate change is the rising sea levels which can lead to reef drowning or coral bleaching. [40] Human activity, such as fishing, mining, deforestation, etc., serves as a threat for coral reefs by affecting the niche of the coral reefs.

Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists declared Monday, a result of warming ocean waters amid human-caused climate change. Coral ...
The group is working to restore 5 acres of coral reef in Puerto Rico by planting fragments across six reefs and returning long-spined sea urchins to the ecosystem.
Warm-water coral reefs are very sensitive to global warming and ocean acidification. Coral reefs provide a habitat for thousands of species. They provide ecosystem services such as coastal protection and food. But 70–90% of today's warm-water coral reefs will disappear even if warming is kept to 1.5 °C (2.7 °F).
Derek Manzello, coordinator of NOAA’s Coral Reef Watch Program, said in a news briefing Thursday that around 60.5%, or nearly two-thirds, of the world’s coral reefs have experienced heat ...
