Approximately 35% of global greenhouse gases (GHGs) come from agriculture. Some argues that human can reverse global worming by sequestering several hundred billion tons of excess CO2 through regenerative, organic farming, ranching and land use. Increasing the soil’s organic content will not only fix carbon and reduce emissions, it will also improve the soil’s ability to retain water and nutrients and resist pests and droughts.

To mitigate GHG emissions and retain soil fertility, organic agriculture might be a wise choice for decreasing the intensive use of synthetic fertilizers, protecting environments, and further improving crop yields. Recent research showed that replacing chemical fertilizer with organic manure significantly decreased the emission of GHGs. Organic farming can reverse the agriculture ecosystem from a carbon source to a carbon…
