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.
The long awaited report from the US Army Corps of Engineers on how to keep Asian carp out of the Great Lakes has finally been released. The report evaluates the many waterways connecting the Mississippi River to Lake Michigan –all potential avenues to allow several species of Asian carp into the Great Lakes. The 5 year report costing $20M is titled Great Lakes and Mississippi River Interbasin Study (GLMRIS).
Silver and bighead carp already make up about 95% of the biomass in rivers downstream of the Chicago River. Over a century ago Chicago built a canal to reverse the flow of the Chicago River to divert their sewage and stormwater south into the Mississippi rather than their waterfront beaches. The “reversed” Chicago River flow has been supported by two US Supreme Court decisions.
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.
From the raging torrents of the Niagara River to the placid Welland Canal one can walk for ten miles through the wooded forest gardens of the Niagara Escarpment. Here in some patches, old growth giant oaks and maples soar above wild ginger and may apple. This shady glen has spectacular lookouts over the Niagara Fruit Belt to Lake Ontario, such as Queenston Heights and the Woodend Conservation area. These wilds overwhelm relics of 19th century assaults on nature, such as lime kilns, a “haunted” “ghost” tunnel under which the Bruce Trail travel and the stone ruins of the abandoned Third Welland Canal.
Dr John Cherry, a hydrogeologist with the Council of Canadian Academies (CCA), says fracking wells in Canada aren't built for the long haul; they tend to spring leaks.
"In my view, well integrity is likely the most important shale gas issue," said Dr Cherry in Toronto, Thursday, May 29. Dr Cherry chaired the CCA's expert panel on understanding the environmental impacts of shale gas extraction (fracking). This panel released its report in early May.
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.
Halifax, NS – Sierra Club Atlantic welcomes the ban of the import of dangerous fracking waste announced today in Nova Scotia. Last spring, Sierra Club launched a petition calling for the ban, and the NS Liberal Party promised to ban the import of fracking waste in the lead up to the provincial election last September.
“This is a relief for Nova Scotians and Nova Scotian municipalities who feared that we were going to be tasked with dealing with toxic fracking waste in the region,” according to Gretchen Fitzgerald, Director of Sierra Club Atlantic, “I am thrilled to see the leadership in this province demonstrate they are taking the threat represented by toxic fracking waste seriously.”
