It seems over the past few years.... A prime example is 2017, when the number actually peaked and around 17 right whales were killed on the east coast in the gulf area, specifically in the Bay of Fundy.
Can you explain why? Is it that we have bigger boats and more gear, or is it to do with climate change, the warming waters and the whales maybe feeding in different areas than they used to? Do we know why this is happening?
