Growing Healthy Food

The farming land availability on our planet is a constant. But food need is an ever growing problem. This has forced human kind to almost double the density of planting. But the soil has limitations and and the increase in planting density had to be sustained by application of fertilizers. Along with human population increase insects and micro organisms too multiplied forcing use of pesticides and the like. This has made our food highly toxic. Clean food with mass productivity is the need of the hour.
