This week on Terra Informa correspondent David Kaczan investigates the proposal for a hydroelectric project on the Lower Churchill River in Labrador. Rebekah Rooney talks with Dr. Craig Tweedie from the University of Texas at el Paso about what he calls the arctic’s Carbon Bomb. And Brett Tegard looks into composting human waste using fungi. But as always to start off the show we have this week’s news headlines with Tasneem Karbani and Steve Andersen.
2,4-D Ban in Quebec
In Quebec, a legal case between the province and Dow AgroSciences has been settled. Dow sought 2 million dollars in damages stemming from the province’s 2006 ban on the cosmetic use of the company’s week killer 2,4-D. In the settlement, Quebec acknowledged that the chemical is safe, provided it is used as directed and Dow agreed to drop its claim for monetary damages. Quebec does not plan to change its legislation, saying that the chemical is unnecessary. (Globe & Mail, Manitoba Co-operator)
New TTC Trains
The Toronto Transit Commission launched its new line of subway trains last week, dubbing them the Toronto Rocket. They’re designed to be faster and more reliable while carrying 10% more passengers than the current system. The new trains are part of an expansion to the subway system that will extend it 8 km to the York Region. The vehicles were built in Thunder Bay by Bombardier and begin regular service in June.

NDP Shadow Cabinet
Edmonton-Strathcona MP Linda Duncan is no longer critic for the environment in the new cabinet announced by Jack Layton. Duncan’s new post will be as the official opposition critic for Aboriginal Affairs and Northern Development. Halifax MP Megan Leslie, the former health critic, is the new environment critic taking over from Duncan. She will be facing off against Environment Minister Peter Kent on environmental issues.

Senior bureaucrats have told the federal government that the export capacity is one that Canadian industry does not need. The critique was part of a federal environmental evaluation from Natural Resources Canda. The document also noted the rising public opposition to Enbridge’s proposed project and concerns about potential oil spills. The documents were released last week after an Access to Information request from the Toronto-based research group Environmental Defense. ( Vancouver Sun, The Province, Financial Post)
A small conservation group and one of its members that sought to protect a fish habitat witnessed a victory last week as the BC Supreme Court dismissed a mulit-million dollar damage claim against them. The Glen Valley Watersheds Society and two individuals had been sued after speaking out about concerns over a landfill application in Aldergrove. The concern was that the landfill would have a negative impact on the fish-bearing streams nearby. The total claim from the landowner against the parties was $13 million. Justice Catherine Bruce of the BC Supreme Court concluded that the claimant had greatly exaggerated the statements made by the respondents and fabricated other allegations.

Proposed Hydroelectric Project on the Lower Churchill River in Labrador
One of the few environmental issues on the table in the recent federal election was a proposal for a hydroelectricity project on the Lower Churchill River, in Labrador. And although it does promise huge amounts of carbon free electricity, much of it for export, some people in Labrador are pretty concerned about the environmental impacts of such a megaproject. Correspondents David Kaczan and Dana Harper investigate.
The Arctic’s Carbon Bomb
Evidence of climate change is mounting from across the globe, but nowhere is it more evident than around the poles. Permafrost in the Tundra is an important carbon store, but unfortunately, once it melts it may release that carbon into the atmosphere triggering a positive feedback loop. Dr. Craig Tweedie from the University of Texas at el Paso, calls this the arctic’s Carbon Bomb! He studies changes to Tundra vegetation and the interactions between plants and animals in the Arctic. Last week he gave a talk on his research at the University of Alberta, where Terra Informa correspondent Rebecca Rooney caught up with him.
Composting Human Waste Using Fungi
When most people think of natural garbage disposal, they think of composting. Composting works exceedingly well in the natural world; organic material can be quickly broken down and recycled back into the soil. But when human waste is too toxic to be composted, the cleanup can be long and difficult. Today, Brett Tegart takes a look at the development of a new solution to repairing environmental damage: using mushrooms to eliminate pollution.
