How do humans threaten coral reefs?
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.
What you can do to help protect coral reefs?
What Everyone Can Do
- Live Sustainably. Reducing your carbon footprint is one way to fight the effects of global warming and lessen large-scale threats to reef ecosystems.

What are the benefits of coral reefs?
Benefits from coral reefs can be categorized into 2 types: “direct use values” (fisheries and tourism industry), and “indirect use values” (benefit derived from coastline protection).
Why are coral reefs important?
Also, their beauty makes coral reefs a powerful attraction for tourism, and well managed tourism provides a sustainable means of earning foreign currency and employment for people around the world, even in remote areas of developing countries. Several attempts have been made to estimate the value of coral reefs in terms of dollars.
Why are coral reefs called rainforests?
Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield . Aside from the hundreds of species of coral, reefs support extraordinary biodiversity and are home to a multitude of different types of fish, invertebrates and sea mammals.
Why are coral reefs important?
Coral reefs are some of the most diverse and valuable ecosystems on Earth. Coral reefs support more species per unit area than any other marine environment , including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be millions of undiscovered species of organisms living in and around reefs. This biodiversity is considered key to finding new medicines for the 21st century. Many drugs are now being developed from coral reef animals and plants as possible cures for cancer, arthritis, human bacterial infections, viruses, and other diseases.
How do coral reefs benefit local economies?
Local economies receive billions of dollars from visitors to reefs through diving tours, recreational fishing trips, hotels, restaurants, and other businesses based near reef ecosystems. Coral reef structures also buffer shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, property damage, ...
What are the healthy coral reefs?
Healthy coral reefs contain thousands of fish and invertebrate species found nowhere else on Earth. Learn more and view a larger image. In the 1890s, harvesting sponges was second only to cigar-making in economic importance in the Florida Keys.
How do coral reefs support fisheries?
Healthy coral reefs support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation. Approximately half of all federally managed fisheries depend on coral reefs and related habitats for a portion of their life cycles.
What happens when coral reefs are damaged?
Once coral reefs are damaged, they are less able to support the many creatures that inhabit them and the communities near them. When a coral reef supports fewer fish, plants, and animals, it also loses value as a tourist destination.
Why are coral reefs important?
Healthy Corals are the foundation of our ocean’s food chain, from tiny plankton to the largest animals in the sea. And coral reefs are important to our economy, too. Healthy coral reefs contribute to fishing and tourism, providing millions of jobs and contributing to economies all over the world.
How do coral reefs support fisheries?
Healthy coral reefs support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation. Approximately half of all federally managed fisheries depend on coral reefs and related habitats for a portion of their life cycles.
Why are coral reefs so endangered?
Despite their great economic and recreational value, coral reefs are severely threatened by pollution, disease, and habitat destruction. Once coral reefs are damaged, they are less able to support the many creatures that inhabit them.
What are the effects of human activities on coral reefs?
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.
How have humans impacted the ocean's coral reefs?
How have humans impacted the ocean’s coral reefs? Much ecological literature focuses on the effects that human actions have on species, habitats or ecosystems. Unfortunately, human effects on the natural world are often negative. Whether it’s deforestation, carbon emissions, plastic pollution or industrialized fishing to name a few, ...
What are coral reefs called?
Beautiful in color, shape and the diversity of species they harbor, corals have been called the rainforests ...
Why are corals called the rainforests of the ocean?
Corals have also earned the nickname “canaries of the sea” because, like the canaries miners carried underground to warn of noxious gas leaks, they readily respond to changes in environmental conditions, ...
Do coral reefs have benthic communities?
Importantly, this research suggests that at populated islands, coral reef benthic communities are not determined by the natural surrounding environment , but by something else: human presence, or at least impacts associated with human presence.
1. Replacing Harmful Ingredients
It turns out, some of the products humans been using for years are actively harmful to coral reefs, so we’re finding better alternatives to replace them with.
2. Keeping Pollution Out of Waterways
Nutrient pollution is one of the worst types of pollution for coral reefs. Agricultural waste, fertilizers, and human sewage are full of nutrients like nitrogen and phosphorus.
3. Preventing Physical Harm to Coral Reefs
Perhaps the most obvious way people can protect coral reefs is by not physically disturbing them. Well, that’s easy, just don’t touch them, right? Unfortunately, human-inflicted damage to coral goes far beyond the occasional overzealous scuba diver.
4. Supplementation with Artificial Reef Structures
Using artificial reef structures might sound like we’ve already given up hope for coral reefs and that we’re now simply looking to replace them. But in fact, artificial reef structures can encourage new coral growth in areas that may otherwise be inhospitable—think flat, barren areas or places that have been dredged or degraded.
5. Coral Restoration Efforts
Unfortunately, most of the above rests on changing people’s habits and actions, which is incredibly difficult to do. Plus, even if all of that changed overnight, we’re still in for significant warming for years to come. That’s why many scientists are placing the most hope (and effort) into coral restoration research.
