The World Wildlife Fund Canada (WWF-Canada) is one of the country's leading conservation organizations. For over 50 years, we've been working toward a future in which humans live in harmony with nature. National Sweater Day is just one of the ways to reduce wasteful consumption.
By rethinking how we use energy and how much we use, we can make a big impact on climate change. If every Canadian lowered the heat a few degrees this winter, it'd be like taking 300,000 vehicles off the road! So wear that sweater and make the world a better place.
You have to visit the site and watch the video, it is also very entertaining.
