Canada is a very large country, with areas of land in various climatic regions and land regions, with many ecozones that differ from each other. Canada's most populated ecozone is the Mixedwood Plains; the ecozone we are in, which takes its name from the mixed forests native to the area. The Mixedwood Plains is one of Canada's smallest ecozones, measuring just 175,963 square kilometers. The Mixedwood Plains are bordered by three of the large lakes on the southern side of the ecozone and extend along the St. Lawrence River into southern Quebec and fill the tip of Ontario. It has rolling plains and small rock formations and escarpments. The Mixedwood Plains is home to over half of Canada's population as it contains some of Canada's largest cities, including Toronto, Ottawa, Montreal, and Windsor. The Mixedwood Plains have a relatively temperate climate with average summer temperatures ranging from 18°C ​​to 22°C and winters ranging from -3°C to -110°C.[2] Native mammals of the ecozone are black, brown and grizzly bears, gray wolves, coyotes and foxes, raccoons, squirrels and other small mammals. Avian species include brown sparrows, hawks, crows, cardinals, and jays. The fish are bass, trout, carp and pike. The Mixedwood Plains are approximately 40% water and contain more than 20% of the world's freshwater. One of the biggest problems in the world today is the shortage of fresh water. Because we have abundant supplies of it, we don't realize it, but much of the world is short of water. There are multiple water resources, but one of the largest is rapidly becoming polluted and populated by invasive species. Pollution is something we create. It is man-made. We pollute our air and, very importantly, our water. The Great Lakes is one of...... half of paper......reversible. Humanity should not need incentives to act on very serious problems like that of the great lakes. Works Cited[1] “Mixedwood Plains.” Canadian ecozones.
