Former Cheers star Ted Danson has called for better practices to protect the world's oceans from over-fishing and contamination. Danson - who played bartender Sam Malone on hit TV sitcom Cheers - is a member of lobby group Oceana, and he wants more to be done to protect the sea. The actor founded the American Oceans Campaign in 1987 to bring national attention to environmental issues. The group later merged with Oceana to bring the cause to a global level. He says, "This is not about saving fish from the goodness of our hearts or taking care of our oceans because we want to be thought of as environmental. It is economic. It is moral, and it is public health. "I guess it's really tough to get people to focus on this great big, beautiful, gorgeous ocean."
