There are some scientific experiments that are so big, they cannot be done in a lab. That is why a small corner of Northwestern Ontario has been set aside for the scientists with those big ideas. It is called the experimental lakes area. Fisheries and Oceans scientists are trying to replicate what happens on a much larger scale elsewhere, for example acidification of lakes or flooding of peat bogs and dry forest. Their findings are now used to help mitigate the environmental impact of projects such a hydro electric dams.
