Hydraulic fracturing (fracking) is a technique for extracting oil and natural gas from rock formations by injecting high-pressure fluid to create fractures that release trapped hydrocarbons. The process has dramatically increased oil and gas production from previously inaccessible formations, transforming energy markets. Fracking is controversial: supporters cite economic benefits, energy security, and lower natural gas prices; opponents raise concerns about groundwater contamination, induced seismic activity (earthquakes), air quality impacts, and climate change from expanded fossil fuel production. Provincial governments regulate fracking, with some jurisdictions imposing moratoriums or bans. Municipalities near fracking operations face both economic opportunities and community concerns about impacts. The debate involves balancing energy development, economic benefits, environmental protection, and community well-being. Water use and wastewater disposal from fracking operations require careful management.
