A comprehensive review of Canada’s freshwater ecosystems reveals rising threats from pollution, overuse, invasive species and climate change among other problems. Yet, the biggest threat of all may be a lack of information that hinders effective regulation.
With a mere 0.5 per cent of the world’s population, Canada has jurisdiction over 20 per cent of the global water supply – a vast and valuable resource that is largely taken for granted by those who depend on it.
