Ari Berman is one of the people I’ve learned the most from reading on voting rights and history. This is bad bad. The SAVE act could crush democracy for so many.
Breaking: House passes new version of SAVE Act, worst voter suppression bill considered by Congress. Could disenfranchise:
-21 million Americans w/out access to citizenship papers
-69 mil married women who took partner’s name
-21 mil w/out valid drivers license

The GOP’s “show us your papers” bill Is the latest effort to help Trump take over elections
“If the SAVE Act were to pass, it would be the worst voter suppression law that Congress has ever enacted"

Ocean science and conservation communication friends, I am hoping to lead a symposium at IMCC: International Marine Conservation Congress about new tools and trends and approaches.
Ideally it would lead to a multi coauthor publication.

A major win for our oceans. The Federal Court of Appeal has upheld Canada’s decision to list plastic manufactured items as toxic, clearing the way for science-based action on plastic pollution.
