Orcas near Seattle and Vancouver face challenges-     A CBC report says that in order for the orcas to increase their numbers to be a sustainable population, the orcas need:   reduce  salmon fishing, stop ships from dumping  sewage, preventing new pipelines and increased shipping.  there are 75 orcas left in this population.  A new calf wea born this year!  $ have been born in the last year!  You can join the David Suzuki Foundation, as it helps monitor these orcas.
