Imagine your house losing its roof – that's what bleaching is like for coral. Mass bleaching events have become more frequent and severe in recent years, posing a serious risk to the reef's survival. The Great Barrier Reef has experienced several major bleaching events in the past few decades, and the recovery process is slow and challenging.

Water Quality and Pollution

Poor water quality is another major threat to the reef. Runoff from agriculture, including fertilizers and pesticides, can pollute the water, leading to algal blooms and reduced water clarity. This pollution smothers coral and harms marine life. Industrial and urban runoff also contribute to pollution, further degrading water quality. Imagine trying to swim in a murky, polluted pool – that's what it's like for the creatures of the reef when the water quality declines.

Crown-of-Thorns Starfish

The crown-of-thorns starfish is a natural predator of coral, but outbreaks of these starfish can devastate reefs. These starfish feed on coral polyps, and large populations can quickly destroy large areas of coral. Outbreaks are often linked to poor water quality and nutrient runoff, which create ideal conditions for starfish larvae to survive. It's like having a swarm of locusts descend on a field of crops, but underwater.

Fishing and Tourism

Unsustainable fishing practices, such as bottom trawling, can damage coral reefs and disrupt marine ecosystems. Overfishing can also deplete fish populations, impacting the food chain and the overall health of the reef. Responsible tourism is essential, but excessive or poorly managed tourism can also harm the reef. Boat anchors can damage coral, and divers and snorkelers can accidentally break coral or disturb marine life. It's like loving a place so much that you accidentally damage it.
