A lot of hard work, non vehicular labor, local sourcing, and luck, providence, perseverance, and serendipity.
How do you suppose humans did it prior to the invention of the coal mine and oil drill?
Once again - not trying to be facetious or patronizing; just legitimately answering the request.
none of this will make any difference.

well, we didn't use fossil fuels, and there were far fewer of us on the planet. With 8billion fossil fuel addicted people, half of whom are yet to be raised from poverty, riding your bike will make you feel better but wont make any difference.
Only insofar as it doesn't inconvenience me. I'm not trying to convince you of my pov, it's just my personal opinion.
I think that individual action is no more than privileged westerners play acting, and its all for nothing.
Humans are, on average, vicious parasites. Half the world wants big macs and SUVs, the other half aspires to that.
Riding a bike to your local vegan grocer is a hilarious solution to a catastrophically depressing problem.
We're doomed, enjoy it while you can ;)
