Part of my typical Twin Oaks tour rant goes like this:
If you believe in climate change, or peak oil, or the limits of finite resources on the planet then your really only have two choices. You can try to convince people from rich countries to consume radically less (trust me this is a hard sell) or you can get folks to shift their ownership patterns to be more efficient in their use by sharing things.
I get that i am decades ahead of my time with this message. But i like being right, so i will keep pitching it.
If i cant get my radical solutions, except here on the commune, i can be happy about liberal things which are happening elsewhere. Here is a recent European effort. These two miles of tunnels were built for noise abatement (not protection from trees as this article claims) and designed to support these 16,000 solar panels providing enough electricity to power 4,000 trains.
