Sharks…More Important Than Ever

Did you know that there is a much greater chance of being killed by a cow than by a shark? About 5 times greater.

It's time to change the “Jaws” narrative and properly value sharks for their amazing contributions to the health of our Great Barrier Reef.

Sharks are vital to ocean health—without them, marine ecosystems can collapse.

Many sharks are top predators. Because of this important role, their loss can have ripple effects through the food chain that throw the entire reef ecosystems off kilter.

When shark presence is reduced, an increase in smaller predators that prey on herbivorous fish is seen. The result? Without enough herbivorous fish feasting on algae, it can quickly grow out of control and take over the reef, eventually reducing biodiversity and diminishing the reef’s resilience to threats like as storms and coral bleaching.

The sad reality is that sharks now need our help to carry on performing their vital ecosystem services.

Sharks are declining at a staggering rate. More than one third of shark species are currently threatened with extinction. There are 71% percent fewer sharks in the open ocean today than there were 50 years ago.

Humans are the main culprit, killing an estimated 100 million sharks every year by overfishing. We are also destroying their habitat, particularly in coastal areas. This massive loss of sharks is harming the underwater ecosystems that rely so heavily on them.

All the threats sharks face are amplified by the fact that most sharks are slow to mature and have babies. We are fishing out many species faster than they can reproduce.  

Having more sharks around to perform their critical ecosystem functions keeps our reefs healthy. That means efforts to conserve sharks benefit more than just the sharks themselves; they help the entire reef.
