The president of the United States must be unable to contain himself.

That’s what I believe is happening as Donald J. Trump seeks to undo some valuable environmental regulations designed to do those silly things … such as provide for cleaner air to breathe.

Trump continues to p*** me off. And a lot of other Americans, too.

As Reuters reported: “Flanked by coal miners, Trump enacted his ‘Energy Independence’ executive order at the Environmental Protection Agency. A coalition of 23 states and local governments vowed to fight the order in court.”

What does this mean? Here’s what I believe it does: It rolls back many of the regulations enacted during the Obama administration that are aimed to promote alternative energy production.

You know … things like wind, solar, hydropower. The clean stuff. The sources that regenerate immediately and are far more environmentally responsible than digging and drilling for fossil fuels such as oil and coal.

Trump will have none of that, by golly. He said he’s keeping a campaign promise to bring jobs back to the coal industry. He also pledged to make America totally “energy independent.”

Interesting. The United States already has become the world’s largest producer of fossil-fuel energy. Are we still importing some of the crude? Yes, but our imported-oil-to-domestic-production ratio has been declining steadily over the past decade or so.

I recall during the 2016 presidential campaign how Republicans and other foes of Hillary Rodham Clinton skewered her over remarks she made about supposedly “putting the coal industry out of business.” They never mentioned, of course, the rest of Clinton’s statements in that regard, which dealt with job-retraining for those former coal-mine workers.

Trump seized on Clinton’s statements and beat her senseless with the half-truths about what she had said.

Now he’s signed an executive order to bring all those coal jobs back. At what cost? Are we going to pollute our air with carbon emissions? Are we going to keep contributing — as scientists around the world have affirmed is occurring — to the gradual warming of Planet Earth?

Yes, human activity is contributing to that potential worldwide disaster.

One more point needs to be made.

We have done much to clean our air and water while at the same time producing more energy from more alternative sources than ever before.

The president is just flat wrong on this one.
