In recent times throughout New Brunswick, big projects like the Mactaquac dam have tried to harness the power of water for hydroelectricity. What are some of the impacts that a big project like this has had? Have students make a list of some of the impacts from the ideas suggested below;
There are many significant environmental effects when a dam is built. These can include: people had to move, erosion occurred , there is a loss of the fishery, water contamination, hydro-electric power is created, more energy and cheaper cost for consumers, often flooding, and new beaches are created.
What is the difference between a beaver dam and a man-made dam? Which one is better for the environment?
When the environment is modified there are consequences. Think back to what you studied about Wolastoq (Saint John River). A dam could impact Indigenous rights to the waterway which they have used for thousands of years. Why do you think that Wolastoqewiyik, Peskotomuhkati or Mi’kmaq would not want to give up the rights to access or use the river routes?
