Organic farming is a type of agriculture that benefits from the recycling and use of natural products. Use of dried plants not only saves money, but also ensures the growth of crops. The technique is characterised by the use of green manure (肥料), biological pest control methods and special farming techniques to keep soil productive. Limiting the use of manmade chemicals or completely doing away with them reduces the risk of diseases. Today, organic farming is a major and preferred industry around the world. Organically grown products have a huge market, with farmlands covering about 10% of the total world farmland.

Advantages of Organic Farming：
•The economics of organic farming are characterised by increasing profits (利润) through reduced water use and reduced soil erosion (侵蚀).
•Organic farming produces the same crops as those produced through traditional farming methods, but uses half the energy, and holds 40% more top soil.
•Organic farming enables farmers to get rid of weeds without the use of any chemicals.
•The use of green pesticides is environmentally friendly and does no harm to human's health.
Disadvantages of Organic Farming：
•Organic methods of farming produce less, compared to traditional farming techniques.
•Organic agriculture does little to fight global climate change. Though organic farming practices are recognised as giving out less CO2, but not to a significant degree.
