So wait, what things make me a pathetic coward? Could you make a list?
And if it is only relating to fossil fuels, I'd wager 99.99% of the population doesn't want fossil fuels to be banned without replacements or serious societal change. Does that make 99.99% of people also pathetic cowards?
Then who goes first? Do we all agree at once to stop using? Or will militaries be exempted because you and I both know that no government is sabotaging their own power.
How would country's that export oil react do you think? Certain economies almost entirely depend on it, do they just cease to exist at once?
Would there be exceptions for agriculture or would some communities have to starve to death?
What about exemptions for building the replacing technology, or should we cease to use power at all and ration what remains?
There is more complexity to the issue you deem so simple to fix. If you had complete control of the world, how would you go about eliminating fossil fuels without being guillotined by 8 billion people?
