People against Water pollution.
ByI chose David Schindler, David Schindler is Killam Memorial Professor of Ecology at the University of Alberta, Edmonton. His work has been widely used in formulating ecologically sound management policy in Canada, the USA and in Europe. I chose David because he is a respected person that is listened to with many qualifications. Some of his qualifications include founding and directing the Experimental Lakes Project of the Canadian Department of Fisheries and Oceans near Kenora, Ontario, conducting interdisciplinary research on the effects of eutrophication, acid rain, radioactive elements and climate change on boreal ecosystems.

I have also chosen Jagmeet Singh, Jagmeet Singh is a well respected Canadian politician (leader of NDP) with a huge following both online as a international social media star and in political debates as the leader of the NDP. Jagmeet Singh says no excuse is acceptable for the Liberals’ failure to deliver on their 2015 promise to lift all drinking water advisories in First Nations communities. Singh will be campaigning later in Neskantaga First Nation, which had a drinking water advisory issued more than 25 years ago. I have chosen Jagmeet Singh because of how popular he currently is and because of his Influence on a large portion of the Canadian population.

Here is what Jagmeet Singh has to say on getting clean water for indigenous people. https://globalnews.ca/video/rd/ba79059c-e784-11e9-921e-0242ac110004/?jwsource=cl
