WHY HELP SHARKS?
Sharks are beautiful, enigmatic and extremely important animals that are often misunderstood.
In 2014 studies carried out by specialists and 5 of the worlds leading marine science bodies estimated that between 63 million and 273 million sharks are killed each year! Sharks are vital to ocean ecosystems; as apex predators they play a critical role in balancing marine ecosystems; their decline is having catastrophic consequences, and there is a very real danger that shark populations will totally collapse and extinction will follow. We have no way of knowing what that could mean for marine ecosystems, but scientists are predicting very serious consequences that will effect us all.
