It is true that energy cannot be destroyed. It can only become another form of energy. People are energy. What does this mean as to life after death? I hope to turn into a dog.
SUD's will kill us before anything else. It's not because they kill ocean dwellers by choking them to a slow, agonizing death, which makes me want to puke even thinking about it, it is horrible and unacceptable, but the amount of energy required via fossil fuels to make them is staggering. You can at least rip your plastic six pack holder's rings so there are no loops left to wrap around some poor dolphin's snout and choke it to death. You can at least do that.
Electric cars won't change anything. What if we all had electric cars that need to be charged? The amount of energy that would need to be expended to create all of that juice would be just as bad or even worse than it is now. Yes, emissions would decrease but still. It's a lot.
Which do you think contributed most towards our present day western civilization - The Magna Carta, the Black Plague or the Battle of Hastings?
