He's definitely not afraid of tough work, the risky part is what is unclear. Like how risky? Like are you risking your life out there? I read about how one of the sea shephard boats not made for the ice got stuck up in ice/glacier waters. Also read how its not ab-normal for them to be shot at with water cannons... crazy stuff. I think they sound like an amazing and important organization. I just hope they take their own safety of their crew into high consideration.
