The hit movie Finding Nemo follows a clownfish from the Great Barrier Reef. In real life, clownfish are among the thousands of colorful sea creatures that call the Great Barrier Reef home.Stretching l,250 miles along Australia' s northeastern. coast, the Great Barrier Reef is the longest coral reef in the world.

A coral reef is a living underwater structure. But these days, the Great Barrier Reef has found itself in trouble.Overfishing, pollution, and high temperatures are harming its health. That's why

the government in Australia is trying to help rescue the reef.

Underwater Garden

While coral may look like a plant, it is actually made up of tiny sea animal.Those sea animals are called coral polyps.

As polyps die, they leave hard.shells behind. Other polyps grow on top of the shells.Over thousands of years, they form a coral reef in warm water that is not very deep.

In many ways, the Great Barrier Reef resembles an underwater garden. Coral can be hard or soft.It forms in different colors and in strange shapes.Some coral looks like hardened brains. Other coral looks like fans and lettuces.

The reef bursts with schools of tropical fish, dashing among gaps in the coral. The reef supplies food. and. shelter to creatures living in and around the coral. Turtles, sharks, sea horses, and crabs are among its many inhabitants.

Helping Humans

While the reef is important to ocean life, it helps humans, too. People rely on the reef for both food and jobs. It also provides medicine used to treat disease. Each year, the Great Barrier Reef contributes about $ 975 million to the economy through tourism and fishing.

At the same time, warmer sea temperatures have caused coral bleaching(漂白) on half of the reef. The high temperatures cause the coral to turn white, often killing it.

Volunteers using the phone walked slower and with shorter steps (and slowest of all when typing), and! more seriously, they locked their arms and elbows in-like “robots", in the researchers' words.That forced their heads to move more, throwing them off balance.

“In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for hits, falls and traffic accidents," said Mr.van den Hoorn.“The best thing to do is to step aside and stop, or keep off the phone."
