After 10 North Atlantic right whales were killed in Canada's Gulf of St. Lawrence over the past two months, the Canadian government is ordering certain ships to reduce speeds to prevent more deaths. 2017 has been the deadliest year for the endangered mammal since scientists began tracking their numbers in the 1980's. Vessels that are 20 meters or longer are temporarily restricted to a maximum speed of 10 knots in the western portion of the Gulf.
