The third principle of humane technology: It should take human values as a cornerstone of its development. Technology doesn't have to be expensive or electronic to be humane. Think of it as the Occam's Razor of humane technology. The simpler the solution, the better the outcome. For instance, the Hippo Water Roller makes it significantly easier for poor, rural communities to haul water from a lake or river back to their homes. Rolling water, rather than carrying it, reduces stress on the body and frees up time for other tasks. Taking human values into consideration for technology goes beyond basic humanitarian aims. The development of humane tech should consider the fact that any new device will be nested within a rich network of social actors. Designers needs to keep an eye on the societal and environmental ramifications of novel technologies and act accordingly.

These might not be the most Next Nature-esque technologies we have featured here, but they're certainly worth a ponder.
