Are you certain you'll have a smaller footprint? By all my calculation, I can't have less an impact on climate/biodiversity than by living in a flat in a city.

No remote, least heating, public park (instead of a private garden, which is comparatively not good at all for biodiversity), still buying food from local farm, etc. Frugal urban lifestyle always beats the rural unless you're a farmer for the many.
