Housed in the largest geodesic (spherical or Buckey ball) structure in the world, this ecological-watch center is an exclusive venue to better understand major environmental issues, including those related to water, air, climate change, sustainable development and responsible consumption. This structure use to be the American pavilion for the World Exposition '67 whose outter transparent platic membrane was damaged by fire in 1976. It contains four rooms of interactives exhibitions about the water ecosystem. Don't forget that there is a 25% rebate for users of green transportation (walking, bicycling, in-line skating or public transit). If you use to metro to get there, don't forget to take a transfer in the metro if you paid using a ticket or exact cash (just show your tourist card or monthly/weekly card otherwise). It is worth the visit just for the sphere itself (especially if you are interested in water or ecological information or... if you just want a great view of the St-Laurent river and Montreal). Here's a more detailed description of the Biosphere:
"The Biosphère raises the awareness of young people and their families, as well as the general public, about the major environmental issues related to water, climate change and the sustainable development of the Great Lakes-St. Lawrence ecosystem. The Biosphère presents permanent and temporary exhibitions, and offers interactive and guided activities that are as informative as they are amusing. It also offers a Youth Program whose educational activities may be carried out at the museum or off-site."
