"When we get to the situation of an obligate salmon-eating population of marine predators - our southern resident killer whales - it should be obvious that if there are insufficient salmon for the whales' dietary needs, whale survival will be at risk, regardless of what the merchants of doubt have said," Balcomb told The Dodo.
Recent political developments, like the emphasis on fish farming, energy development, export and mining have threatened this vital food source. Balcomb said that the only hope for recovery of the whale population rests with recovery of the natural salmon populations. And the way to do that, he says, is to vote for salmon-friendly policies - and to vote against measures that will hurt the salmon.
"Voters in California are deciding to erect more dams and diversions of water for human use in a region of drought brought about by climate change, when we already know that dams are lethal to salmon populations...This system will not work - people must recognize the problem with honest evaluation, and vote to change it."
