While fish and chip shop customers in South Australia are eating threatened and endangered shark species labelled as “flake”, sharks are facing the risk of being extinct. As a 2020 study concluded sharks were “functionally extinct” on 20% of the world’s coral reefs. A new study building on this research from the journal Nature Communications shows that now 2 in 3 of the worlds sharks are being driven to extinction. The cause is clear and simple: overfishing. What will be the effects on the ocean ecosystem? What consequenses will this have for humans? And why do sharks have such a bad image?
