This week, Living on Earth contributor Peter Dykstra and Host Jenni Doering discuss the clean energy infrastructure popping up in former fossil fuel strongholds. Also, waste pickers who comb through trash to glean recyclable metals and plastics are asking for a seat at the table in the negotiations for a global plastic waste treaty. And in history, they look back to when scientists debunked the “Piltdown Man” hoax fossil.

Time and again nature has come up with diverse ways that species can succeed in their environments.

The world is way off track from the Paris Agreement goal to limit warming to 1.5 degrees Celsius.

Alden Meyer of the climate think tank E3G joins Host Steve Curwood to explain.

As solar energy costs fall and installations of solar panels rise, some are raising concerns about the materials they’re made from and are promoting disinformation about the safety of recycling these modules. A team at the National Renewable Energy Laboratory clarified this waste from solar panels and recently published an essay in the journal Nature Physics. Lead author Dr. Heather Mirletz joins Host Jenni Doering to put solar panel waste in perspective.

Many of the chemicals used in fracking for natural gas are hazardous to human health, but loopholes in disclosure laws mean that companies can keep them secret. So Pennsylvania’s Governor is moving to compel companies to disclose the chemicals they use in fracking operations. Environmental Health News reporter Kristina Marusic joins Host Steve Curwood to explain the health risks and disclosure challenges.
