Sharks not to blame; humans taking their food
Sharks are coming closer to shore to find food, not humans. Humans are the ones that are taking their food by overfishing, so they are coming closer to shore to find food.
People on a surfboard, on a kayak with legs dangling over the side, on a rubber raft splashing around are figures that look like a turtle or a seal to a shark. And if you splash around in the water, it thinks it’s a fish in distress and will move toward it.
Don’t blame the sharks, you are it their domain. You are the one that need to be aware of your surroundings.
