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.
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.

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.
Natural Capital refers to the stock of natural resources and environmental assets, and how they contribute to building healthy communities. The Natural Capital perspective is a way of placing a monetary value on the ecological goods and services to quantify these benefits.
Brampton's ecosystems contain many natural areas and urban green spaces that provide the city with ecological goods and services, which translates to valuable Natural Capital.
Thanks to support from Ontario Trillium Foundation and the Mississauga Community Fund, we are expanding the project by doing walkshops and natural area restoration work throughout Brampton and Mississauga in summer of 2014. Our goal is to educate and engage the community to raise awareness and appreciation for these natural areas.
Sierra Club Canada's Ontario Chapter was instrumental in the decision by our provincial government to shut down all coal plants. The day has come! Toronto environmental lawyer Dianne Saxe has a nice piece on her website about it:
Goodbye to Nanticoke, and all that coal
by DIANNE SAXE on JANUARY 15, 2014
January 8 marked the last day of operation of the Nanticoke Generating Station, the last operating coal-fired electrical generating facility in southern Ontario. This latest shut down will help mark 2014 as the year Ontario will become a coal-free jurisdiction.
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.
