The outer environment is the world around the work place. The inner environment is the work place. The author cites as per the criteria, their impact on the quality of life. Waste disposal is of prime importance in considering environmental degradation. Such problems are found in all types of human activity. Our understanding of the cause and effect of environmental pollution is complicated by certain findings. For example, what may often be inoffensive in small quantities can get concentrated in pockets and may enter the food chain and life cycles in quite unexpected ways, getting structurally transformed in the process. An example is the spread of chlorinated hydrocarbons like DDT or BHC and their concentration in bird and animal tissues. Another example is the concentration of mercury, arsenic, lead etc. in living tissues, mainly fish. An example of a different type, less malevolent perhaps, is the residual effects of open pit mining. As a solution to such problems, Recuperation and Recycling is the most feasible option. More and more materials formerly considered waste, are being recycled, reconditioned and recovered. Literally, this is production of wealth from waste. For technical personnel education should concern. I) What impact will his activity have on the outer environment? 2) What can be done to reduce the ill effects from the above? 3) How can the short term, and long term costs and benefits be evaluated? The inner environment affects the technical person more directly and in the short term. The main issues here are 1) organisational risks 2) equipment related risks 5) process related risks and 4) product related risks. These are mostly straightforward cause and effect relations and are easily perceived - but not necessarily rectified. Rural Development Through Education System 150
