But tilling those deep-rooted grasslands released massive amounts of underground carbon into the atmosphere. More greenhouse gases wafted into the skies when wetlands were drained and forests cleared for fields. Land conversion continues today, and synthetic fertilizer, diesel-hungry farm machinery, and methane-belching livestock add to the climate effects; all told, farming generates 10% of climate-affecting emissions from the United States each year. Now, Congress would like to turn back the clock and return some of that carbon to the soil.
