Why choose organic foods?!

Because organic means it does not use pesticides and other human made chemical products which in many ways are toxic to humans.
For the vast majority of human history, agriculture can be described as organic; only during the 20th century was a large supply of new synthetic chemicals introduced to the food supply. This more recent style of production is referred to as "conventional." Under organic production, the use of conventional non-organic pesticide (including non-organic insecticides, fungicides, and herbicides) is precluded. However, contrary to popular belief, certain sprays and other materials that meet organic standards are allowed in the production of organic food. If livestock are involved, the livestock must be reared with regular access to pasture and without the routine use of antibiotics or growth hormones. In most countries, organic produce may not be genetically modified. It has been suggested that the application of nanotechnology to food and agriculture is a further technology that needs to be excluded from certified organic food. The Soil Association (UK) has been the first organic certifier to implement a nano-exclusion.
USDA Organic: In 2000, after a 10-year development process, the U.S. Department of Agriculture (USDA) rolled out its rules covering use of the word "organic" on foods. The USDA accredits independent certifiers, who then check the claims of producers. The system has three levels:

"100% Organic": Can only contain organic ingredients, meaning no antibiotics, hormones, genetic engineering, radiation or synthetic pesticides or fertilizers can be used. Can display the USDA organic logo and/or the specific certifying agent's logo.
"Organic": Contains 95% organic ingredients, with the balance coming from ingredients on the approved National List. These products can also display the USDA organic logo and/or the certifier's logo.
"Made with Organic Ingredients": Must be made with at least 70% organic ingredients, three of which must be listed on the package, and the balance must be on the National List. These products may display the certifier's logo but not the USDA organic logo.
