What is the great barrier reef used for?

It's important to protect the great barrier reef because it's a refuge for many species of conservation concern.its ecosystems provide habitats for nearly 9000 species. The queensland government is working with many partners to protect the great barrier reef now and for future generations.

The great barrier reef is essential in preserving the coastline.In fact, corals absorb wave energy and thus help reduce coastle exosion. Coral reefs notably reduce the power of storms

The causes

Climate change is the biggest threat facing the great barrier reef, alongside problems that are more manageable. The combined impact of multiple threats makes it harder for the reef to recover from serious disturbances

The consequances

Also

The health of the reef has signifantly declined over the past three decades. Coastal developments, pollution and humans interference all pose major threats, disrupting wildlife and destroying habitat. The reef has also suffered multiple mass coral bleaching events as a result of global

habitats are changing wich creates competition for food and shelter in cold waters, threatening the entire ecostystem. For reef communities, the loss of marine life can have a devastating impact on local ecosystems, food sources and other industries such as tourism.

The numbers

• 50% of the world's coral reefs have been lost

• 97% of reef had died in great barrier reef

• 95% of the reefs are severly bleached
