Coral Reefs are Undersea Treasure, We need to protect them

Healthy coral reefs are beautiful, awe-inspiring ecosystems — owing to the enormously rich biological diversity found within and above them. These sublime environments attract human visitors like bees to honey.

Economic and environmental services: they offer an abundant supply of seafood and protect the shoreline from waves, storms, and floods.

Priceless Resources in Peril
Unfortunately, a brief look at the news explains the grim story about coral reefs. Rapid warming, accelerating pollution, and destructive fishing practices are decimating coral reefs faster than they can adapt to survive.

Just as damaged and degraded coral reefs lose their appeal to divers and snorkelers, they also fail to provide the sustenance and coastal protection on which we depend. It’s clear that successful coral reef conservation efforts benefit us as well as the reefs.

Saving the Reefs Starts with the Shore
Sediment runoff and surges in algal cover caused by nutrient pollution from land are among the main causes of injury to coral reefs. Identifying and controlling pollution on land has direct benefits for coral reefs as well as water users within the region.

Fishing for Tomorrow
Overexploitation of key marine wildlife species, which are essential for balancing the ecosystem, is severely damaging coral reefs. Sharks and lobsters are prime examples. Some industrialized fishing techniques and certain types of gear also are causing major damage to coral structures.
Minimizing the destructive effects of over fishing, and achieving responsible, ecosystem-based stewardship of reef fisheries pays lasting dividends to healthy coral reefs and to those who make a living from the sea.

Building 'Bridges' to Help Corals Survive Climate Change
Corals face a major threat from climate change in the form of warmer and more acidic oceans, which cause mass bleaching and slow the growth of coral skeletons. Reducing greenhouse gases is essential to corals’ long-term survival. In the meantime, boosting the resilience of coral reef ecosystems and reducing local stresses are bridge solutions until the overarching climate threat is reduced.
Think Reef
Whether you live one mile or one thousand miles from a coral reef, your actions affect the reefs’ future — and the reefs’ future affects yours. There are a host of reef-conserving tips we can all make use of in our everyday lives that can also benefit for our own pocketbooks:

• Don’t use chemically enhanced pesticides and fertilizers. These products ultimately end up in the ocean, via a stream, lake, estuary, or a wetland.
• Conserve water. The less you use, the less runoff and wastewater pollute the oceans.
• Use more efficient electrical appliances and lighting, and keep them turned off when not necessary. You’ll reduce waste, save money, and lessen your climate change impact.
