How likely are you to climb into the waters off Nova Scotia to get up close to a great white shark? A marine ecologist and shark researcher based is hoping it’s appealing to a lot of people this summer. Neil Hammerschlag is the owner and president of Atlantic Shark Expeditions, a Nova Scotia company offering expeditions out of Liverpool this summer. He says ecotourism is a great way to teach people about sharks by letting them get up close to the creatures, but in a way that keeps the humans and sharks safe. And part of the mission is to use the revenue to offset the costs of his white shark research.
