Research has determined that fracking negatively affects human health and drives climate change. [2] [3] [4] Fracking fluids include proppants and other substances, which include chemicals known to be toxic, as well as unknown chemicals that may be toxic. [5] In the United States, such additives may be treated as trade secrets by companies who ...
Since then, over 170,000 oil and gas wells have been fractured in Western Canada. [1] [2]: 1298 Fracking is a process that stimulates natural gas or oil in wellbores to flow more easily by subjecting hydrocarbon reservoirs to pressure through the injection of fluids or gas at depth causing the rock to fracture or to widen existing cracks.
Fracking According to available studies on its environmental relevance, the fracking technology in unconventional natural gas production – particularly in shale gas production – is a technology with enormous potential risks. The effects on humans, nature and the environment are scientifically not yet sufficiently clarified.
The second approach relies on the precautionary principle and the principal of preventive and corrective action of environmental hazards, using the best available techniques with an acceptable economic cost to insure the protection, the valuation, the restoration, management of spaces, resources and natural environments, of animal and vegetal species, of ecological diversity and equilibriums.

Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, particularly from unconventional reservoirs.

For the Canadian prairie provinces and the arctic territories, the Prairie Weather Central was established in Winnipeg by 1967. The smaller Weather Offices in support of the Prairie Weather Central included Edmonton, Whitehorse and Regina, Saskatchewan. [7] [8] In 1971, the weather service was moved to Environment Canada, a new Federal ...
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats.As one of the world's significant emitters of greenhouse gasses, [1] Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts.
The Canadian weather radar network consists of 33 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation , its motion and the threat it poses to life and property.
