Organic Food

Once upon a time, all vegetables and fruits are organic, farmers did not know about chemicals and pesticide to plant vegetables and fruits, they used organic fertiliser to make plants grow well and fed the people in the world.

Later on knowledge about chemistry has been discovered and people invented many different kinds of chemical stuff to 'improve' harvest and kill harmful insects, up to a point that people started to beware of the fact that many of these chemicals have harmed the lands in the world and also harmed human life.

People looked back human history and found that organic food is natural and free of chemicals, then people set rules to control the definition of organic food and then organic farmers start to cultivate crops in organic way, but the cheap organic food in the old days became costly now and is not affordable by the public.
