Foods that are produced using methods that do not involve modern synthetic inputs such as synthetic pesticides and chemical fertilizers, do not contain genetically modified organisms, and are not processed using irradiation, industrial solvents, or chemical food additives are called as Organic Foods.
Hard to believe but each decision we make to purchase a product will make enormous difference to ecology in itself. Ex: If we decide to buy organic pulses we are not only benefiting our health but also the farmer who has his quality of life improved by Not exposing himself to harmful chemical pesticides, getting a fair price and better economic advantage over a long period of time. Along with that fertility of soil is improved and species beneficial to the crops thrive in the area maintaining ecological balance.
This immense commercialization of agriculture has had a very negative effect on the environment. The use of pesticides has led to enormous levels of chemical buildup in our environment, in soil, water, air, in animals and even in our own bodies. Chemical fertilizers have a short-term effect on productivity but a longer-term negative effect on the environment where they remain for years after leaching and running off, contaminating ground water and water bodies.
