Shark Allies is a conservation group dedicated to restoring and conserving the shark population by improving shark conservation policy. They are trying to raise awareness about the consequences of a world without sharks.

“It would be very scary without sharks because so many different species depend on them,” Cassandra Scott said.

Marine experts said people need to be more aware of the seafood they eat. They need to pick more sustainable catch, continue to reduce plastic consumption, and sign up for beach and ocean clean-ups.
