Re "Global Clout via fracking" (Page A1, Nov. 29): My husband and I share the deep concerns about the many dangers of fracking, and we felt that writer Tim Johnson did not adequately relay these in his two articles about the industry. Fracking causes ground subsidence, or sinking, as well as poisonous water pollution when toxic chemicals leak into groundwater, thus leading to major health, agricultural, and environmental problems. Johnson also did not include the fact that, while scientists report that fossil fuels cause major global climate disruptions, fracking leads to increased use of fossil fuels. So we are seeing melting ice caps and ever harsher weather conditions, including storms and floods creating adaptation challenges for our entire planet. Instead of allowing fracking, the United States should use its clout to help protect our diminishing water supply and develop and use alternative fuels.
