Animal husbandry made things worse, as domesticated animals began grazing grasslands down to the earth.
In places wehere the ground is bare - from overgrazing or from the common practice of leaving fields unplanted for part of the year - photosynthesis stops. Lal calculates that land use changes such as these have stripped 70 billion to 100 billion tons of carbon from the world's soils and pumped it into the earth's atmosphere, oceans, and lakes since the dawn of agriculture. - Geography Trivia / Ireland - "The shape and landscape of present-day Ireland—an island of 27,100 square miles [70,200 square kilometers]—were formed 10,000 years ago when Atlantic Ocean glaciers slowly began their retreat.

Larger settlements like Jericho arose along salt and flint trade routes. This chronology was called into question in 1996 by new archaeological evidence.
Northern Eurasia was resettled as the glaciers of the last glacial maximum retreated. Following a two-year study commisioned by the English Heritage Foundation, researchers concluded that the great circles of blustones and sarsens had in fact been put up between 2,600 BC and 2,030 BC. - Neolithic Age - "According to popular history, this period [10,000 - 8,000 B.
Chert, jasper and quartzite were often used by humans during this period. With the right stewardship, Lal says, the agricultural soils of the world have the potential to soak up 13 percent of the carbon dioxide in the atmosphere today - the equivalent of scrubbing every ounce of CO2 released into the atmosphere since 1980.
[....] For millions of years, a natural partnership between plants and soil microbes has helped regulate carbon dioxide levels in the atmosphere.
Some of those carbon products transfer from the roots to symbiotic fungi and soil microbes, which store the carbon in soil as humus.Everybody needs company, no matter what their age is.No other community does more for the safety of its members than Stitch.[NP] The invention of agriculture some 10,000 years ago disrupted these ancient soil-building processes.When humans started draining and plowing up the natural topsoil for planting, they exposed the buried carbon to oxygen, creating carbon dioxide and releasing it into the air.
