Cars also directly involve people in motor vehicle accidents, one of the leading causes of death in the developed world. Cars, and motor vehicles in general, also contribute to an increasingly alarming concentration of emissions into the atmosphere, with adverse effects to follow, most notably global warming. My point still stands.
A technology is only inherently good if it solves more problems than it causes, with each problem weighed by their impacts on the world.
Oh really? Since when?
Edit: Just in case you weren’t convinced.
If you go into the sampling and analysis specifics, the chemistry is sound. There are a few assumptions made, as with any data sampling technique, but if you decide to want to dispute such details, you may as well dispute the technical details and call your objection there. Otherwise, I don’t see where your claim holds, this is one of the better documented global disputes (makes sense, since so much is at stake with regards to both the industry involved as well as the alleged consequences of climate change.)
I can say that global productivity increase doesn’t mean anything if it cannot be sustained.
