Watersheds directly affect water quality, whether it’s for drinking or recreation. For example, algae blooms or anoxic events resulting from nutrient rich runoff draining into waterway, harm watershed health, as do pesticides and contaminants. PEI is dependant on its ground water supplies so extreme care must be taken to protect it.
An Unhealthy Watershed
Watersheds affect wildlife. The polluted water supply that results can become harmful to humans. Aquatic life quickly suffers the effects of watershed pollution while new pollutants introduced into ecosystems alter wildlife habitats. This reduces biodiversity by eliminating some species and introducing new, invasive ones that destroy the native species. That, in turn, can affect the food chain in our watershed, from microbial organisms that feed birds and animals to fish that feed humans.
