As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org
There is No Scientific Justification to Revoke the Endangerment Finding
The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

All individuals of a species come from the complex interactions of their genes and their environment, & the rich developmental endowment epigentically inherited from the parent.
Nothing can replace or recreate that.
In this Anthropocene, once lost, the species is lost forever.

Some libraries have relied on animals to help protect their collections, and some libraries lean into noble animal symbology, others are cheerfully tolerant of their local sympatric species. #2026MMM
