Organic food is grown without the use of synthetic pesticides and fertilizers, a fact that can be helpful not only for the people who consume the food but for the ecosystems in which the food is grown, which may suffer from exposure to these synthetic farming tools. There is evidence to support the idea that organic farming supports much-needed biodiversity, and worker health on organic farms may also be better than on those farms that use synthetics to fight pests and nourish plants. Some people may also believe that organic food is overall more healthy to eat because it does not introduce harmful chemicals into one's diet.
These factors may only be considered "important" by those who care about conservation, sustainability and the health impact of items such as genetically-modified plants and synthetic pesticides that are developed by humans and do not occur in the natural world. However, there are arguments to be made for the health and quality of organic foods such as organic meats. Because organic livestock tends to be fed a more balanced natural diet, these animals may produce better quality meat. Additionally, because organic produce isn't grown with the use of synthetic fertilizers, it must be grown in high-quality soil, which may result in better fruits and vegetables.
