But, after the 9/11 attacks, I took a good hard look at myself. You could say, the blowback factor was real.
Now I live in a modest house just outside the city where I work, and I can cycle into the city in 40 minutes through a green landscape when the weather is good. My family and I are avid gardeners and grow our own veggies for 4/5th's of the year - sourcing it from local farmers for the rest of the time when our garden is sleeping for winter. We cook for ourselves like demons, and have massively improved health as a result. My children are taller and stronger than their peers, because they've been raised on home cooking and fresh vegetables where their peers were not.
I also ride electric, always and only - a small, weak, underpowered electric moped gets me through the city comfortably, and I recharge it every few days from house power, derived from renewables (solar and wind). Its pretty much ideal in terms of carbon footprint.
It took a big change however. I had to leave the USA and now live in middle Europe (Vienna, Austria) - a country that has long since decided to upgrade the standard of living of its people through smart economic policies designed to reduce dependence on petroleum. Its not perfect - there is still a lot of work to do in my community - but its certainly better than the, frankly disturbing, lifestyle I led in the USA.
The point is, the resources are there. People can actually massively reduce their carbon footprint if needed. You may have to move - far and wide - to escape the city trap. If you are spending more than an hour every day in your car, just to support your lifestyle, this is a clue that you MUST change. Every hour spent in traffic is a crime against the planet.
