Solid waste policy in the United States produce large amounts of waste in small areas. For example, EPA reports that a single dairy cow produces approximately 120 pounds of wet manure per day equaling to that of 20-40 people. The main problems of animal waste mismanagement are environmental, especially water pollution. Industrial waste consists of a significant amount of solid waste. EPA reported that each year United States industrial facilities generate and dispose of approximately 7.6 billion tons of industrial solid waste based on 1980s figures. This figure includes waste generated from 17 industrial manufacturers of organic chemicals, inorganic chemicals, iron and steel, plastics and resins, stone,
Per stirpes children "C" and "D" survive, so the estate is divided at their generation. There were three children, so each surviving child receives one-third. The remainder - "B"s share - is then divided in the same manner among "B"s surviving descendants. The result is the same as under "per stirpes" because "B"s one-third is distributed to "B1" and "B2" (one-sixth to each). Example 2B: The "per capita" and "per stirpes" results would differ if "D" also pre-deceased with one child, "D1" (figure 2). Under "per stirpes", "B1" and "B2" would each receive one-sixth (half of "B"s one-third share), and "D1" would
