Farmer Gabe Brown talks about how he rebuilt the soil on his ranch using no-till farming, cover crops, and grazing animals. The talk was recorded at a sustainable agriculture symposium in Idaho in 2014.

Dr. Bruce Bugbee walks through the calculations for crop yield potential when light is the limiting factor, from photosynthetic quantum yield through respiration efficiency and harvest index, using the Energy Cascade Model.

Kirsten Dirksen visits retired mailman Russ Finch in Alliance, Nebraska, who grows oranges, figs and pomegranates in a backyard greenhouse without paying for heat. The greenhouse uses the stable temperature of the earth, with underground earth tubes, to heat and cool itself.

A short documentary about Eric Maundu's Arduino-controlled aquaponics setup in West Oakland, where contaminated soil rules out ordinary farming. Fish and circulating water grow plants without soil.

Sabine Hossenfelder explains climate sensitivity and why recent observations suggest climate models may have underestimated warming. She says this changed her view on how worried to be.

Farmer Joel Salatin gives a TEDx talk on how well-managed grass and rotational grazing support sustainable farming and affect the climate. He draws on his work at Polyface Farm in Virginia.

Marcin Jakubowski of Open Source Ecology presents his plan to open-source blueprints for 50 cheap, buildable farming tools, a "civilization starter kit". He argues that opening the means of production can enable self-sustaining lives.

A long talk by rancher Gabe Brown on turning his North Dakota farm into a regenerative ecosystem using no-till, cover crops and integrated livestock. It covers the five principles of soil health and how they pay off financially.

The first video in potholer54's climate series, giving a basic look at how climate scientists infer that man-made carbon gases are changing the climate. It is a short explainer meant to present the scientific evidence plainly.

Thai farmer Jon Jandai talks about leaving Bangkok to farm and build his own house, arguing that food, shelter, clothing and medicine are easy to provide and that modern life is made needlessly complicated. He founded the Pun Pun Center for Self-reliance.

A Kurzgesagt video on the conditions in which most farm animals are raised. It argues that cruelty is for cheaper rather than better meat, and that a small price increase per meal could avoid most of the suffering.

A Motherboard documentary episode from Nebraska about farmers and mechanics fighting manufacturers like John Deere over access to the diagnostic software needed to repair modern tractors. It shows how software locks have taken away farmers' traditional self-reliance.

A Kurzgesagt animated explainer on meat: why people love it and what it costs animals, the environment and health. It lays out the complicated trade-offs of meat production and consumption.

Cirrus introduces Safe Return, an emergency autoland system for its Vision Jet. A passenger presses a single button and the aircraft squawks emergency, reroutes and lands itself.
