The longest coral reef.Off the east cost of Australia stretching2,000 kilometres the Great barrier reef is the biggest coral reef in the world. It is also the largest structure made by any living thing –it is so big it can be seen from space! Corals only grow about15 centimeters every year, so parts of the great barrier reef are approximately 18 years old.
Major threats• Major threats to coral reefs and their habitats include: Destructive fishing practices: These include cyanide fishing, blast or dynamite fishing, bottom trawling, and muro-ami (banging on the reef with sticks). Bottom- trawling is one of the greatest threats to cold-water coral reefs.• Overfishing: This affects the ecological balance of coral reef communities, warping the food chain and causing effects far beyond the directly overfished population.• Careless tourism: Careless boating, diving, snorkelling, and fishing happens around the world, with people touching reefs, stirring up sediment, collecting coral, and dropping anchors on reefs. Some tourist resorts and infrastructure have been built directly on top of reefs, and some resorts empty their sewage or other wastes directly into water surrounding coral reefs.• Coral mining: Live coral is removed from reefs for use as bricks, road-fill, or cement for new buildings. Corals are also sold as souvenirs to tourists and to exporters who dont know or dont care about the longer term damage done, and harvested for the live rock trade.

Conclusion.1. I think there is hope for coral reefs.
