Mar 6, 2015 · Many scientific investigations have documented direct causal effects of human behaviors on coral reef systems: for example, aggregate mining, land runoff of excessive nutrients, and destructive fishing practices. Few, however, have taken a step back to look at how the presence of humans can affect the natural functioning of coral reef systems ...
Human-caused, or anthropogenic activities, are major threats to coral reefs. Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.

The ins and outs of coral reefs can be confusing. Here’s a deep dive into what makes a coral reef, why they’re threatened and how they’re doing now:
Coral reefs are vast, three-dimensional structures comprised of coral animal colonies that secrete calcium carbonate, also known as limestone. Over time, these limestone secretions build up and create structures, some of which can be seen from space. Reefs are built by a variety of hard corals, of which there are 800 different species. The coral co...
Coral reefs are threatened by both local and global threats, including overfishing; sediment, nutrient and marine pollution; and increasing ocean warming and acidification. Overfishing is the most pervasive local threat to coral reefs. It can alter the ecological balance on the reef through removing herbivorous fish that control the macroalgae grow...
Unfortunately, there is no simple answer on the state of coral reefs. The extent of damage to the world’s coral reefs vary, and some have recovered. However, most present a grim outlook. Around half of the world’s reefs are likely degraded from climate change, pollution and overfishing. Hard coral cover has declined significantly in some regions, a...
The decline in live hard coral cover over the past 40 years isn’t the end of the story. Projections of future ocean warming and the associated increased frequency of coral bleaching make coral reefs highly susceptible to further declines. By the 2030s, most coral reefs are projected to experience coral bleaching at least twice per decade, and possi...
There is no one solution to saving coral reefs — many coordinated steps must be taken toward a future where corals persist. On a local level, threats to coral reefs can be addressed by managing fisheries sustainably, eliminating destructive fishing and addressing all sources of pollution. Moreover, management and financial support for MPAs and othe...
The top threats to coral reefs — global climate change, unsustainable fishing and land-based pollution — are all due to human activities. These threats, combined with others such as tropical storms, disease outbreaks, vessel damage, marine debris and invasive species, exacerbate each other.
Feb 21, 2019 · The connection between coral reefs and human health. February 21, 2019 — Coral reefs aren’t just beautiful. They’re the most biologically diverse ecosystems in the oceans, and can provide food, jobs, and protection from storms for coastal communities.
How does coral bleaching impact humans? Coral bleaching impacts peoples’ livelihoods, food security, and safety. Coral reefs are natural barriers that absorb the force of waves and storm surges, keeping coastal communities safe.
Oct 6, 2020 · Global threats facing reef ecosystems. Coral Reef ecosystems are facing many natural and anthropogenic threats. Many human impacts are resulting in the destruction and degradation of coral reefs ecosystem to cause loss in biodiversity, fundamental supplies for food and reef economic revenue.
