Dr. King is often misquoted as having said “Of all of the forms of inequality, injustice in health care is the most shocking and inhumane.”
He actually said “injustice in health”. Although the quote was about medical care discrimination, Dr. King understood that health was more than health care.

It’s no wonder that Trump’s EPA would take this step: avoided premature mortality is regularly the largest category of monetized benefits used to justify Clean Air Act regulation.

Since deaths from particulate matter and ozone are the vast majority of monetized benefits from air pollution regulations, this move will effectively stop most clean air regulations. This is totally unsupported by science, economics, or common sense.
Scoop: The EPA will no longer estimate the lives saved by reducing air pollution when writing clean-air regulations, according to documents reviewed by @nytimes.com.

When people argue that renewable energy sources are too expensive, remember that we don’t invade countries to seize wind farms and there are no solar cartels. Fossil fuels have enormous geopolitical, public health, and climate externalities.
