Picture a landscape buried beneath a sky-high heap of dead plants and animal corpses. This is what Earth’s surface would look like if it weren’t for fungi. Fungi are the biosphere’s recyclers. Human society depends on them absolutely.

For those who speak and write non-Latin languages, being able to type on a ‘standard’ computer keyboard is a major barrier to digital democracy. In Cambodia, this problem has been solved and communities are going wireless.
Human beings are deeply dependent on motorized machines to move themselves around. Trillions of these things now choke a vast and growing network of so-called “roads,” getting into deadly accidents and polluting the planet’s atmosphere.
Human beings can’t decide whether to cherish trees or chop them down. This seems to be the take-away message in a tenth transmission we’ve just picked up from a far-off planet in crisis.
Earth is home to an astonishingly diverse array of creatures — as the voices in this captured transmission recount — but the planet appears to be in the midst of a huge crash.
Ethiopia is renowned for the diversity of its seeds, with native resistance to drought, pests and climate change. Listen to 1989 Right Livelihood Award winner Melaku Worede talk about seed diversity in his homeland, Ethiopia.
