"My doctor called me a canary in a coalmine." A resident shares her story: chronic, debilitating conditions that started out of nowhere - right when Shell's Monaca polyethylene unit came online. Her toxicologist's only treatment recommendation? Leave the area.

Replying to @GovernorShapiro
@GovernorShapiro said a moratorium is something you use when you still need to figure things out. As for data center development, "Well, we figured it out." Not even close. Join us on 10/6 at the PA Capitol to say NO to data center development in PA. bit.ly/NoDataCentersPA

Clean energy infrastructure like Barcelona's Photovoltaic Pergola represents the future. Solar panels aren't just good for the environment, they are symbols of independence.

The U.S. EPA gave a pass to polluters at the expense of public health and welfare – we’ll see them in court. Earlier this week, EPA repealed carbon pollution standards for power plants, despite its obligation to regulate health-harming pollution. catf.us/2026/09/epa-sued-ove…
