Vaccines are among the most thoroughly studied, effective tools we have to protect children from serious vaccine-preventable diseases. Decisions about how and when vaccines are used should be driven by rigorous scientific evidence, patient safety, and independent medical and public health expertise. Altering a proven vaccination schedule without credible evidence risks weakening public confidence and putting children’s health at risk.

If you have questions about vaccines, talk to your child’s physician. Putting our children’s health at risk is not an option

No joke, it would be cheaper to pay every coal miner $5m every year to not mine coal. There are only 40,000 coal miners, while the coal industry produces >$500 billion in external costs every year, including by routinely burning coal just to burn it despite it costing more ("uneconomic dispatch").

Assigning $0 benefits to reducing harmful air pollution means when Trump's EPA *rolls back* clean air safeguards, it also assigns $0 in costs to *increases* in harmful, even deadly air pollution. This scam lets the Trump EPA lie to the public about how harmful their clean air rollbacks are. 7/
