Greenhouse gases include the many heat-trapping trace gases that reside in the earth’s atmosphere. Two common greenhouse gases are water vapor and carbon dioxide. Methane, ozone (03), CFCs, and nitrogen oxides are some others. These gases absorb infrared radiation and help regulate the planet's climate. This regulation is called the greenhouse effect.
We actually need the greenhouse effect to survive on planet earth, but we currently have gasses in such an excess that it's become harmful, resulting in global warming or climate change. Activities such as burning coal and oil, filling up landfills, driving cars with gasoline, raising livestock and other human-based activities create greenhouse gases. Mother Nature issues, such as volcanoes, also result in greenhouse gases, but human activity results in the largest amount of greenhouse gases.
Organic farming is important in relation to greenhouse gases. Data from the Rodale Institute’s long-running comparison of organic farming vs. conventional farming systems shows that organic farming methods are far better for the planet, in terms of global warming because the organic methods remove more greenhouse gases from the atmosphere.
Sustainable and organic agriculture helps to counteract greenhouse gases and climate change because organic farming uses less overall energy resources and organic farming helps to restore organic matter in the soil plus reduces soil erosion.
