Sustainable World: Food and Farming

Product Description

We all need food to survive buty many of us give relatively little thought to where our food actually comes from, or how it is produced. In the last forty years, the world population has more than doubled, placing great pressure on farming to produce enough food to meet its needs. Erosion, water shortages, soil and water pollution and declining yields are all signs that, in many places, the environment can no longer support current farming systems. In such a world there is an urgent need to change farming systems to ensure that in the future there is food for all.
