We need to protect sharks to protect our environment. The traps with a baited hook that are used to attract and snare sharks instead trap them on the ocean floor, leaving them unable to swim.

This is not about public safety, rather it's a blatant tactic to reduce public scrutiny by a government under increased public pressure to end its archaic culling program.
