 Countries with the largest economies and consumer patterns in the world today, often have the most serious solid wastes problem. Household refuse, commercial rubbish, industrial wastes and contraction debris total more than 700,000 metric tonnes daily in the United States alone.  Among the major methods of solid wastes disposal are open dumps, sanitary landfills, incineration, ocean dumping, feeding garbage to swine and composting.

In smaller towns and cities in most developing countries in the continent, you can find on every street and even along the roads, solid wastes litters.

Once the land has been altered and exposed by strip miners, it is ...
