It is the land that has been providing us with everything we need for centuries. In other words almost everything we use daily comes from the land directly or indirectly. The food ,,clothes, houses ,even the books and furniture are all supplied by the land. But the limited land is decreasing at a surprising speed. With the expanding of the cities, the development of the industry and over population ,lots of large pieces of good farmland are being turned into residential areas with many houses and apartment buildings or industrial areas or warehouses.
