Each blue whale has a unique pattern of spots of its back, like a fingerprint or a nametag. These spots allow researchers to identify each whale as either a newcomer, or an old friend.
The Mingan Island Cetacean Study (MICS) is a non-profit research organization located on the Gulf of St Lawrence's northern shore and they were the first group to begin long term study of marine mammals in the Gulf. Since their founding in 1979, this group has followed blue whale populations in eastern Canada, the Sea of Cortez and in the waters of Iceland.
MICS has discovered something troubling in the northwest Atlantic blue whale population. Of the 475 individual whales they've identified since their genesis in 1979, only 22 have been calves. This suggests a frighteningly low calving rate for a population already swimming on the brink.
See an electric vehicle next to you on the road and you might not distinguish it from any other gas guzzler confronting rush hour traffic. But drive one yourself...and you won't soon shake the experience.
Electric vehicles (EVs) are powered entirely by their onboard batteries and therefore have no tailpipe. No combustion engine vibrates under their hood and no gears need shifted, giving these machines an unrivalled smoothness. When faced with stop signs, red lights or drive-thrus, EVs don't expend their power idling - they are incapable of idling.
But for all their blessings, EVs have their drawbacks. Their batteries have limited range, they can't be fuelled at the pump and for the time being, they cost more than your average gasoline vehicle. However, professor of mechanical engineering at Dalhousie University, Lukas Swan, said these drawbacks are being left in the dust.

Rouge Park has been getting a lot of press coverage recently. The proposed federal legislation for Rouge Park is not good enough, and the remarkable ecological values of the park deserve more protection. A letter signed by 7 environmental groups outlining the objections to the legislation for establishing the future urban park can be found here.
Walk To Save Southern Ontario’s Vanishing Forests.
By John Bacher
Today we have a bizarre situation where hard wrested environmental progress is being turned back. This is the shrinking of Southern Ontario’s forests, in the fertile agricultural area south of the Canadian Shield.
Following the invasion of what was called Upper Canada there was a rampant destruction through burning of the forests of the land which, after Confederation, became called Ontario. Most of these forests were used to produce ashes, to manufacture soap and other products manufactured in Europe. It took sixty large maple trees to produce a single barrel of potash to be shipped across the sea.
