Why safer and more nutritious!
Apply natural fertilizers, such as manure(有机肥) or compost(堆肥), to feed soil and plants.
While organic food accounts for 1–2% of total food sales worldwide, the organic food market is growing rapidly, far ahead of the rest of the food industry, in both developed and developing nations.
• Another advantage of organic food lies in its ability to impact us on a global level; minimizing our exposure to chemically altered food and saving our planet from needless contact with unnatural contaminants.

definition
Organic foods are foods that are produced using methods that do not involve modern synthetic inputs such as synthetic pesticides and chemical fertilizers. Organic foods are also not processed using irradiation, industrial solvents, or chemical food additives.
However, critics of organic farming methods believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems.
• Any product labeled as organic must be USDA certified. Only producers who sell less than $5,000 a year in organic foods are exempt from this certification; however, they're still required to follow the USDA's standards for organic foods.
