Dumping
Explanation:
In this method, waste materials are dumped in open low lands far away from the city. This method is not environment friendly. However, this is the cheapest method and does not need much planning. The open pits spoil the sight of the area and become a breeding ground for mosquitoes, flies, insects, etc. The burning of waste material in the open dumps pollutes the air.
