Les cyanobactéries sonnent l'alarme

Canwest a écrit un petit papier bien intriguant. Premièrement, il baptise un sondage d'Ipsos Reid une "étude", comme si çà avait une valeur scientifique. Mais un sondage auprès de plus de 2,000 personnes au travers le pays, c'est pas pire, et çà vaut la peine d'être souligné. 83% des Canadiens sondés s'inquiètent de la qualité de l'eau du lac où ils se baignent, et 2/3 sont sensibilisés au fait que çà ne s'améliore pas!

Et c'est probablement grâce aux algues bleu-vertes: rien comme une soupe phosphorescente pour nous avertir que l'eau n'est pas propre! Il semblerait que les blooms du lac Winnipeg peuvent être vus de l'espace: c'est pas rien!

Je loue l'article pour avoir mentionné le Docteur David Schindler, mais c'est plutôt ironique de lire que la province de Québec aurait mis de l'argent de côté pour s'attaquer au problème des cyanobactéries. À part çà, est-ce qu'on a fait quelque chose?
"Growing concern over Canada's lakes: Study

As the weather warms and beaches beckon, an overwhelming number of Canadians worry that contaminated lakes will threaten their favourite summer swimming spots, results of a study released Wednesday suggest. The Canadian Water Attitudes Study, conducted by the Royal Bank and Unilever, found that 83 per cent of Canadians are concerned about the quality of water in lakes where they swim, and more than two-thirds thinks the water is getting worse. Sandford said lake pollution has plagued every province for years, but he said the issue appears to be gaining traction because of the blue-green algal blooms that are choking lakes across the country and making them unsuitable for swimming.

The technicolour growths, so brilliantly blue-green that they can be seen in satellite images, are caused by contaminants leaching into lakes in the form of fertilizers from urban lawns and farm fields, faulty septic systems and soil erosion. Blue-green algae, which feeds on the phosphorous in fertilizer and raw sewage, then produces toxins that can kill aquatic life and other creatures that venture into lakes that have been overrun.

David Schindler, a professor at the University of Alberta with four decades' work on lake ecology, said every province is now dealing with the problem. In Quebec, after blooms in dozens of lakes have been produced, the provincial government has set aside money to combat the plague. A recent report from the Winnipeg-based International Institute for Sustainable Development highlighted Lake Winnipeg's problems, calling the more than 100,000 farms that surround the lake basin as the main culprits in the pollution.

The online survey of 2,022 adults from across the country was conducted by Ipsos Reid from Feb. 17 to 23. The results are considered accurate to within 2.2 per cent, 19 times out of 20."

So in Quebec, "the provincial government has set aside money to combat the plague", hey? Did we DO something with that money? Was it spent? And on what? Did it change anything?
