OK, so it's going to take a lot more than switching off the TV to "save the world" like a superhero (try unplugging it, for one). On the other hand, every little bit helps, and every day people have to start somewhere... once a person begins feeling good about saving energy, fixing leaky faucets, and recycling, it's not that big a jump to living in an Earthship, using a composting toilet, and flying around in a solar-powered dirigible.

The problem with composting toilets is that you are left with greywater which has to be dealt with. Septic tanks require the solids as well as greywater to provide food for the bacteria, so they won't work with greywater alone. Greywater harvesters are expensive and require electricity, so are not so green and in the UK and most of Northern Europe, we have more than enough water for the Gardens.
Non-electric sewage treatment plants use no electricity for the process and produce clean water which can then be used for irrigation.
