Blaming diesel for a public health crisis is like blaming the sun for melanomas or the wind for wrecked ships.
Yes using diesel has consequences just as fossil fuels does but the upside of them far outweighs the downside and not using it would be far worse.
Things can have both positive and negative properties. Diesel is no exception and has certainly saved more people than it killed.
Diesel is ... cheap that's about it. Everything else about it, is a negative.
I already gave you just some of the positive effects of using Diesel luckily everyone can read for themselves.
That's all on this subject.
Putting diesel in the category of 'sun' or 'wind' is pretty clear I think.
The point is that it's absurd to only look at the negatives. Just like you wouldn't only be judging wind or the sun on negatives you can't only look at the negatives only of diesel you have to look at the positives and THEN decide whether it's worth it.
Why would using petrol be "far worse"?
