Fracking is controversial for several reasons. Firstly, the process uses large amounts of water, which must be transported to the site, posing significant environmental costs. Secondly, there are concerns about the potential for carcinogenic chemicals used in fracking to escape and contaminate groundwater. Additionally, fracking can cause small earth tremors, raising fears among residents. Environmental campaigners also argue that fracking distracts from investments in renewable energy sources, further entrenching reliance on fossil fuels.
