This is why I think it's good that Trump plans to spend the next month campaigning for Republicans: every time he opens his mouth, something epically stupid, racist, sexist, or incoherent comes out. His support for candidates (or sports teams, or anything) is now toxic.

Rachel Carson's "Silent Spring" was released on this day 62 years ago. I have a first edition & come back to it often, including this paragraph in the chapter "Obligation to Endure." It's worth reading. "We urgently need an end to these false assurances, to the sugar coating of unpalatable facts."
Cover of Silent Spring by Rachel CarsonThe last paragraph in the Silent Spring chapter Obligation to Endure, reads, in part, " We urgently need an end to these false assurances, to the sugar coating of unpalatable facts... The public must decide whether it wishes to continue on the present road, and it can do so only when in full possession of the facts. In the words of Jean Rostand, "The obligation to endure gives us the right to know."

A picture I took last night. Two things can be true. 1. Gas prices are skyrocketing because of Trump's illegal war and that's bad for consumers and the economy. 2. Gas prices should be higher because their cost doesn't include the massive environmental and #climate damages fossil fuels cause.
