It is crucial to understand that wiping out an entire superorder of species, such as sharks, would have devastating consequences for the ocean ecosystem. The effects of declining shark populations are already being felt, with an average reduction of 90% in population size across many species, and some experiencing a staggering 99% reduction. Sharks are not a significant threat to human life, as evidenced by an average of 100 reported “attacks” per year, with a death rate of around 20%, resulting in approximately 20 human deaths caused by sharks. In contrast, human activities result in the annual killing of an estimated 73-100 million sharks, primarily driven by the demand for shark fin soup.

Interestingly, sharks play a vital role in sequestering carbon in ocean ecosystems. They help maintain the balance of species by keeping populations in check. This, in turn, contributes to the health of coral reefs. A healthy reef ecosystem is characterized by an abundance of apex predators, creating an environment where smaller fish live in fear and breed rapidly. On the other hand, when reefs lack sufficient predator populations and are dominated by an overabundance of smaller fish, their health deteriorates, leading to their destruction.

For further information and a more comprehensive understanding of the impacts sharks have on ocean ecosystems, I recommend referring to the provided PDF titled “Predators as Prey” by Oceana. This document delves into additional insights and details regarding the important role sharks play in maintaining the balance and health of our oceans.
