Some anti-drilling activists change tactics, tone

      PITTSBURGH (AP) -- For years, activists have warned that fracking can have disastrous consequences -- ruined water and air, sickened people and animals, a ceaseless parade of truck traffic.

      Now some critics are doing what was once unthinkable: working with the industry. Some are even signing lucrative gas leases and speaking about the environmental benefits of gas.

      Some activists say that with drilling in full swing in Pennsylvania and elsewhere, it's no longer realistic to push for a ban or moratorium. Instead, they say, it's better to push the industry to minimize the negative impacts of drilling.

      One recently formed citizens group, for example, seeks to persuade energy companies to use advanced technologies to limit air emissions.
