The Great Barrier Reef is the world's largest coral reef system, located in the Coral Sea off the coast of Australia.

The reef is facing a number of threats, including climate change, pollution, overfishing, and disease, which have caused significant damage to the coral in recent years.

Shipping vessels can release oil, chemicals, and other pollutants into the waters surrounding the reef, which can harm marine life and damage the coral.

1. Pollution

Large ships can run aground or collide with the reef, causing physical damage to the coral and disrupting marine ecosystems.

2. Groundings and collisions

The noise generated by shipping traffic can disrupt the communication and navigation patterns of marine life, including whales and dolphins.

3. Noise pollution

Ballast water discharge from ships can introduce invasive species to the reef, which can compete with native species for resources and alter the ecosystem.

4. Invasive species

Shipping emissions contribute to climate change, which can cause ocean acidification and coral bleaching, both of which can harm the reef.
