To begin with, organic food is generally more nutritious than food grown with artificial fertilisers. In addition, it is beneficial to our health. In fact, it contains much more essential minerals, for instance, vitamins. Finally, what attracts consumers most is its tasty flavour. However, as for chemical farming, it produces food with less flavor and nutrition, which is essential to people. Plus, chemical farming kills not only bad but also good insects and thus damages the land. Therefore, I hold the belief that organic farming brings us more advantages and is more environmentally friendly. sample writing Let the world eat well and be full.
