Future of the Environment

A sixth mass extinction is underway - and it's our fault

Greater Snow geese fly at the Cap Tourmente Wildlife area at St-Joachim, October 26, 2008. According to Environment Canada, at the beginning of the last century there was about 3,000 Greater Snow geese left and the population was on the verge on extinction. Therefore, the Canadian Wildlife Service set up the Cap Tourmente Wildlife area in 1969, one of many measures that helped to increase the number of Greater Snow geese to more than 800,000.
