Morality is an issue for many people who are not Bernie Sanders, but an ethical outlook on climate change is not enough.
What is required to address climate change is familiarity with a) reality, but even more so, b) science.
Bernie Sanders is opposed to the world's largest, by far, source of climate change gas free energy, nuclear energy.
His program, which involves investing in expensive, toxic, and useless so called "renewable energy" is delusional.
It hasn't worked. It isn't working. And it won't work.
The world spent close to two trillion dollars on so called "renewable energy" in the last ten years, and the results of this popular but disastrous approach to climate change is clearly written in the data above.
Because of the policies that Sanders endorses, his state's policy of dumping the dangerous fossil fuel waste carbon dioxide into the planetary atmosphere has risen from zero, to hundreds of thousands of metric tons.
Now. Vermont was, until two years ago, the only state in the Union that did not dump dangerous fossil fuel waste into the planetary atmosphere, and now it does.
As an ethical issue I could not ever imagine myself voting for Sanders to be the Democratic nominee for President. We have an infinitely better choice if climate is the issue, infinite in the sense that she has not announced a policy of making things worse, something Sanders has committed himself to doing.
If, may God forbid, if Sanders is the nominee, I will be forced to vote for him, not because he's good, but because he's less terrible than any of his possible opponents. For me, it will be the worst choice I've had since that reprehensible fool Michael Dukakis ran against that awful man George H.W. Bush.
No person serious about climate change should vote for Sanders.
Have a nice evening.
