This has been going around Facebook lately. All accounts seem to stem from this NaturalNews article. I don't tend to see them as a reliable source of information, but I also haven't found any proof that contradicts their assertion.
Balcomb also remarked:
We haven't had any survivals in babies for a couple of years. We have had stillborns and newborns die and a number of whales that appear to be pregnant but didn't ultimately produce any calves. It's like zero survival in birth rate here.
