A sweet animation of the wonderful Alfred Russel Wallace, the oft unaknowledged simualtaneous discoverer of evolutionary mechanisms.
Some of the greatest discoveries in biology began as spatial discoveries. Alfred Russel Wallace made some amazing advances in biogeography and discovered the appropriately named Wallace Line.

Allan Savory's vision for a more sustainable food system, the “Savory Grazing Method,” facing criticism, and his long-term plans for The Savory Institute.
"Holistic management," is an outdated system that we know will not work. Savoy's work is a rediscovery of rotational grazing management that was tried in the 1940's, and still dominates the policies of public land management agencies. Ecosystems disintegrate under rotation grazing because the system requires too many fine adjustments from year to year. It is no longer accepted by thinking naturalists, because it tends to eliminate wildlife, tear ecosystems apart, and add to the continuing downward spiral of Earth systems. Take a look at what growing human populations require in areas considered for rotational grazing. You will see that we are past the sustainable levels in many areas, and yet demand is still growing. Long-term thinking is needed.
Geology: North America's broken heart Nature.com The volcanic rocks are remnants of what is called the Midcontinent Rift, and it is an enormous geological puzzle. Rifts are wounds in Earth's outer layer that can grow to eventually form new oceans.
