- Be conscious when buying aquarium fish.
- Spread the word!
What are the major natural threats to coral reefs?
Coral reefs are sometimes disturbed by natural forces, such as extreme rain events that dilute seawater, waves associated with hurricane-force winds, volcanism, earthquakes, and thermal stress from unusually warm water (such as El Niño events).
What pollutes the Great Barrier Reef?
Chemical pollution When inefficient fertiliser is applied to crops, like sugar cane, excess fertiliser washes into rivers and waterways, where it is carried out to the Great Barrier Reef. Nitrogen from these fertilisers are linked to harmful algal blooms, which is a food source for juvenile crown-of-thorns starfish.
How can we stop coral reef destruction?

Why do we need to protect the coral reef?
Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef.
How do humans destroy coral reefs?
Careless divers often inadvertently destroy coral reefs by kicking them or dropping anchors from their boats directly onto the coral. In poorer countries, septic waste from resorts often leaks out into the ocean, killing off the fragile corals.
Can SDG 14 save coral reefs?
With estimates that coral reefs are among the most threatened ecosystems on Earth, the dire need for societal-level changes to reduce human impacts on coral reef ecosystems is no longer a debate. The achievement of SDG 14 by 2030 could help improve ocean resources, to be sure.
Is public engagement with coral reefs in crisis good enough?
Public engagement with coral reefs in crisis is woefully low, especially by comparison with many other environmental crises. Societal-level changes are needed in order for coral reef ecosystems to continue functioning.
How has pollution affected the health of the coral reefs?
