I observed many changes over my 82 years of life, and one of the tragedies involves the degradation of soils caused by principles of farming. Human-caused degradation occurs in many ways, from monoculture farming, to erosion created by wind and water exposure, to use of petrochemicals that increase yields while killing microbiological life in the ground, and to overgrazing of herds on pastures. Principles based on production while ignoring impacts on soils, air, and water leads to reduced production and degradation of the elements of soils, water, and air.
Permaculture provides principles that restore the natural flow of all the elements. This farming method has the potential to not only increase productivity but increase elements to healthy conditions.
There are those who resist change, who want to conserve the old ways of production, and who react against ideas that make good sense and positive results. Conservative reaction impedes health to air, water, and soils.

NGC 7822: Stars and Dust Pillars in Infrared
Explanation: What spooky planet is this? Planet Earth of course, on a dark and stormy night in 2013 at Hverir, a geothermally active area along the volcanic landscape in northeastern Iceland. Geomagnetic storms produced the auroral display in the starry night sky while ghostly towers of steam and gas venting from fumaroles danced against the eerie greenish light. Tonight, there is also a chance for geomagnetic storms triggered by recent solar activity, so high-latitude skygazers should beware. Ghostly shapes may dance in your neighborhood pretty soon, too."
Here is an odd-looking feature that tickles the imagination. How did it form, of what is it made, what will it take to find answers?
Explanation: What created this unusual mountain? Ahuna Mons is the largest mountain on the largest known asteroid in our Solar System, Ceres, which orbits our Sun in the main asteroid belt between Mars and Jupiter. Ahuna Mons, though, is like nothing that humanity has ever seen before. For one thing, its slopes are garnished not with old craters but young vertical streaks. One hypothesis holds that Ahuna Mons is an ice volcano that formed shortly after a large impact on the opposite side of the dwarf planet loosened up the terrain through focused seismic waves. The bright streaks may be high in reflective salt, and therefore similar to other recently surfaced material such as visible in Ceres' famous bright spots. The featured double-height digital image was constructed from surface maps taken of Ceres last year by the robotic Dawn mission.
