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.
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.
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.
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.
Scientists studying the blue whale in the Gulf of St Lawrence are reporting alarmingly low calving rates from this critically endangered species, says the Sierra Club Canada Foundation. The Sierra Club recently launched a campaign to safeguard the blue whale's critical habitat in the Gulf.
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.
