Today agriculture and other land-use changes account for about a third of global greenhouse gas emissions. The event left the country rich with the soil that has nurtured Ireland's flora and fauna for centuries, and which offered a hospitable environment for migrating people to settle and plant seeds."- First Nations people / Canada - "Archaeologists have found evidence that proves First Nations people were in New Brunswick more than 10,000 years ago.[....]" [Based on: Discover Magazine article (Could Dirt help Heal the Climate? [NP] For years archaeologists suspected the First Nations history might go way back because there had been small, individual finds, but Hurricane Earl helped reveal even more.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.
However, the highly successful human occupation of the area that began approximately 10,000 years ago depended largely on cultural adaptations, rather than biological ones.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.During photosynthesis, plants absorb carbon dioxide from the air and transform it into sugars, carbohydrates, and other carbon-based molecules.Some of those carbon products transfer from the roots to symbiotic fungi and soil microbes, which store the carbon in soil as humus.In this 7,000 year span, we see the first colonization of the altiplano, the settling of permanent villages, and the rise of chiefly societies that formed the basis of Tiwanaku, one of the high civilizations of the New World.
