Plastic is polluting our ocean and damaging our health, and there are widespread calls to get rid of it. But it isn't as simple as wishing the pervasive material away.
Water is something that every living thing needs, but it can be problematic making sure that water gets to every living thing - not just people and animals, but plants as well. Irrigation is important for farming, but it's often ineffective and wasteful.

Update: This comment thread on reddit for the podcast episode is red hot right now. This is an excerpt from this week's podcast where I argue that permaculture is failing. Sustainable agriculture faces a crisis. In many ways this crisis reflects the broader social and economic breakdown crisi

There's a cultural phenomenon, one that has been growing for the past decade, of hobbyist hackers exemplified by Make Magazine and TechShop. These hackers want to have the experience of building something in the physical world while still applying the tools and techniques of computing. With the rise of open hardware platforms like Arduino-even whole systems like the Raspberry Pi for $25-it's surprisingly affordable for people to program their own electronics.
We take a tour of Poland's emerging permaculture scene and find that forest gardening, formerly a traditional way of producing food for families, is gaining popularity once again as is the movement against industrial agriculture.
