We now live in a modest house, on several acres so that we can raise a fair amount of our own produce.
We drive small, high gas mileage cars.
Our house is heated by a natural gas well on the property.
And we're frugal. We buy things, when needed, keeping in mind that they need to last for many years. This often means we buy rebuilt appliances, etc. from the 50s-70s due to the better materials used and absence of un-repairable electronics.
Some would call it "living for Gaia"...I call it "going Galt".
This is precisely why many uninformed Christians are being taken down the green garden path.
