More bad news for the world’s oceans - out of Canada!

A team of Canadian researchers has found that BC’s premier oyster-growing region off the east coast of Vancouver Island, is “highly contaminated” with micro plastics. The team, from Simon Fraser University, says it is now important to find out if the oysters themselves are ingesting the plastics. If they are, it could have implications for the health and quality of the product itself, Canada’s oyster-farmers, in general and the entire industry, worldwide.

 The scientists found micro-plastics at all 16 sites sampled within Lambert Channel and Baynes Sound, indicating "widespread contamination of these regions with these particles." That is Canada's prime growing area for the Pacific oyster (Crassostrea gigas).

 It is also feared the microplastics could accumulate trace metals which, in turn, could harm the oysters and other organisms on the sea-bottom.

Three types of micro-plastics were recovered and identified, with microbeads being the most common.

Are hungry kids a priority for the Harper government? by Larry Powell The forum (for the riding of Dauphin - Swan River - Neepawa) was sponsored by the Mission and Services Committee of the Neepawa United Church. It drew about 80 people to the church on Wednesday. But only four of the five candidates (see below) took part in the debate -  Ray  Piché  (Liberal),   Kate Storey (Green Party),  Inky Mark (Ind.) and  Laverne Lewycky (NDP) . The 5th candidate, the sitting Conservative MP for the area, Robert Sopuck (represented by the empty chair on the right), did not attend. His office manager in Neepawa, Christine Waddell, said he was in Inglis, a small community in the western part of the riding for the evening. She did not elaborate. But she did explain that a campaign worker was mistaken when he told forum organizers earlier that Mr. Sopuck would, in fact be there. Piché , the Liberal candidate, said the MP's absence showed “disrespect” for the rest of the candidates

A Candidate's Forum on Child Poverty Touches a Nerve in Manitoba.

by Larry Powell Planet In Peril has sorted through some of the confusion surrounding the absence of Robert Sopuck (above), the Conservative Member of Parliament for Dauphin-Swan River-Neepawa,  from a candidates' forum on child poverty in Neepawa on Wednesday.  About a month ago, his office told forum organizers that he would be attending.  But his office manager in Neepawa, Christine Waddell, later announced he could not attend due to "scheduling conflicts." She said the night of the event, he was in Inglis, a small town in the western part of his riding.  This morning, however, Sopuck himself told PinP he had actually been in Roblin, a larger town just north of Inglis. A newspaper ad indicated it was a "meet and greet" affair. But that was in the morning in Roblin, a town within a 3-hour drive of Neepawa. So it's still not clear what the event in Inglis was which took priority over a candidate's forum. The MP bristled at my suggestion th
