The Iran war has cost thousands of lives and billions of dollars. It is too soon to calculate its cost to the environment and human health, but according to the United Nations Environment Programme, even if the current conflict were to end soon, it would cause lasting damage. #chemsky 🧪

Leopards and their spots.
Screenshot of a tweet by Melanie D’Arrigo criticizing a man accused of sexual assault, quoting a post from Aaron Rupar. The quoted tweet shows Donald Trump saying, “We’re gonna have to force ourselves upon them, which we have the right to do.” The image shows Trump seated at a desk in the Oval Office, speaking, with framed photos and flags visible behind him.

I have never wavered in my position that there can be no compromise with RFK Jr. He is a dangerous fraud who has caused incalculable damage to public health. It’s extremely disappointing that the President of the American Medical Association was doing a photo op with RFK Jr. this morning.
Post from me from December 2024 that says RFK Jr. is not trained in any area of medicine or science. He has never applied for a research grant, conducted an experiment, or published a peer-reviewed paper. We should never, EVER compromise with people who lie about vaccines and public health.
