Coral reefs cover less than one percent of the ocean floor, but they support about 25 percent of all marine life.
These colorful underwater structures are some of the most important ecosystems on Earth.
A coral reef is made of tiny animals called polyps, which build hard skeletons over thousands of years.

Thousands of species of fish, plants, and other sea creatures live in and around coral reefs.
Many coastal communities depend on coral reefs for food, as local fishermen catch fish that live near the reefs.
Coral reefs also protect coastlines from powerful waves and storms by acting as natural barriers.
However, coral reefs around the world are in serious danger today.

Rising ocean temperatures cause a process called coral bleaching, which turns the coral white and can kill it.
Pollution from farms and cities also washes into the ocean and damages the delicate reef ecosystems.
Tourists who touch or step on coral can break these slow-growing structures that took centuries to form.
Governments and scientists are working together to create protected marine areas where reefs can recover.

Individuals can help by reducing plastic waste, supporting sustainable seafood, and learning about ocean health.
If we act now, coral reefs can survive and continue to shelter millions of ocean creatures.
The [ocean's] future depends on the choices we make today.
