What would happen if sharks disappeared?
It is a terrifying prospect to imagine what could happen if they were to disappear – sharks have existed since the time of the dinosaurs and ocean life has evolved with them.
Sharks play a crucial role in the ocean ecosystem as apex predators, keeping marine life in balance. For example, by keeping certain prey numbers in check, they prevent overgrazing of seagrass, a plant that can store carbon at around 35 times the rate of tropical forests.
If sharks were to disappear the implications would be disastrous, not just for sharks themselves, but for the wider marine environment and the people who depend on it.
