Soil Isn't Sexy

Soil Isn't Sexy | GarryRogers Biosphere News | Scoop.it

"Soil is the earth's fragile skin that anchors all life on Earth. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans...Half of the topsoil on the planet has been lost in the last 150 years." WWF

"Desertification is a phenomenon that ranks among the greatest environmental challenges of our time, unfortunately most people haven't heard of it or simply don't understand it.

"Desertification and land degradation is a global issue with desertification already affecting one quarter of the total land surface of the globe today

"Today the pace of arable land degradation is estimated at 30 to 35 times the historical rate. Land degradation is costing US$490 billion per annum and desertification is degrading more than 12m hectares of arable land every year - the equivalent of losing the total arable area of France every 18 months.

"Every morsel of food we eat . . . our clothes . . . our houses and most everything that's in them...each scrap of paper, from birth certificates to books to dollars...our fuel...even the very oxygen we breath: All of it comes from plants, trees...and topsoil."

Garry Rogers's insight:

Soil erosion is the least-mentioned major crisis of all.  When do all humans begin to mourn the wealth of the planet Earth that we have squandered?

A year after a California wildfire known as the “Rim Fire” burnt through over 250,000 acres of Sierra Nevada forests, environmentalists and loggers are debating what to do with the blackened woodland it left behind. The timber industry believes that chopping … Continue reading →
Garry Rogers's insight:

Logging healthy forests destroys soil microorganisms and reduces forest diversity.  Logging burned forests is even more destructive.  Access roads and equipment movements promote erosion, introduce weeds, damage surviving undergrowth, and crush the new tree seedlings that would replace the original forest.  Logging these fragile environments reduces watershed values and slows recovery.  Only an agency such as the U. S. Forest Service that is controlled by the profit-motivated logging industry would approve logging a burned forest.
