<P> Throughout history, waste has been generated by humans . In areas with low population density waste generation may have been negligible . In higher population areas even largely biodegradable waste had to be dealt with . Sometimes this was released back into the ground water with environmental impact like Nor Loch . The Maya of Central America had a fixed monthly ritual, in which the people of the village would gather together and burn their garbage in large dumps . </P> <P> Following the onset of industrialization and the sustained urban growth of large population centres in England, the buildup of waste in the cities caused a rapid deterioration in levels of sanitation and the general quality of urban life . The streets became choked with filth due to the lack of waste clearance regulations . Calls for the establishment of a municipal authority with waste removal powers were mooted as early as 1751 by Corbyn Morris in London, who proposed that "...as the preservation of the health of the people is of great importance, it is proposed that the cleaning of this city, should be put under one uniform public management, and all the filth be...conveyed by the Thames to proper distance in the country". </P>

When did solid waste disposal become a problem
