Now it takes 10 units of fossil fuel energy to produce and deliver one unit of food energy, even though the solar energy to grow the plant is free.This has implications not only for the health of the soil but also for the health of the people and animals consuming the food grown in it.
Old-growth forests have dwindled and, in many places, disappeared.
Over the Great Plains of North America, vast herds of bison and elk roamed, spurred by predators (primarily wolves and, after we arrived, human beings) to bunch up in herds for self-defense, then move on, leaving urine, saliva, and dung to revitalize the land. Within the last century, however, this topsoil has been exhausted by farmers deep-plowing and planting grains, primarily corn and, more recently, soybeans.where agriculture extracted nutrients and carbon out of soils and then farmers moved on to areas with undisturbed soils to repeat these soil-degrading practices.
In 2018, China, the biggest carbon polluter on the planet, was on track for its biggest increase since 2011, 4.7 percent, and the United States is on track for its largest increase since 2013, 2.5 percent.
The US increase coincided with the second year of Donald Trump’s presidency, after he began rolling back pollution controls in an effort to strengthen the faltering coal industry while opening up large tracts of public land for oil and natural-gas drilling.
Children clamber around the edges of the trench while the adults crouch or stand, listening to a woman pacing at the bottom, pointing out roots and different layers of exposed earth, talking about how the soil can save us from a climate catastrophe.
The speaker is Nicole Masters, an agroecologist from New Zealand, conducting a workshop on soil health for this audience of ranchers, farmers, and conservationists.
Adding to this surge were the massive summer fires on the prairies and in the mountains of my home state, Montana, followed by giant blazes in other Western states.
Last year, a snowy winter and wet spring, with rains extending well into the summer, kept the fires down in Montana, but they blazed anew in other Western states, and one conflagration almost completely destroyed the town of Paradise in Northern California.
Masters’s message is that while replacing fossil fuels with clean energy from the sun, wind, flowing water, and the planet’s own heat is certainly necessary, it is not enough. Soil microbes eat sugar.” And feeding these soil microbes builds soil and sequesters atmospheric carbon in the ground “at a rate previously thought impossible.” The workshop at the Charter Ranch took place in May 2015.
To stop runaway global warming, tame the fierce extremes of weather we are now experiencing, slow down and eventually reverse the melting of icecaps and glaciers, rescue drowning islands, and revive dying coral reefs, we must also find a way to remove excess carbon from the atmosphere and sequester it in the soil. Four years later, our climate situation has grown more dire and the carbon-sequestration message even more urgent.
