Waste Problem Management The accumulation of solid wastes is a serious problem that threatens the environment of the entire planet and will continues its exponential growth due to the increasing population and industrial development. The component of municipal solid waste of major concern to the environment is the putrescible fraction that accounts for 50-80% of its total dry weight. The economic and environmental problems associated with the disposal of municipal solid wastes world-wide represent a real threat to civilization. For hundred of years the management of solid wastes generated in Urban centers has challenged humanity to find an effective solution for its disposal. Some of the practices used to manage the problem in the past include burning, ocean dumping and open damps. The first landfill was built by the Greeks 2,500 years ago. Despite the advances of science and the many years of experience handling MSW, the majority of disposal methods of MSW are very similar to the ancient practices. The most common disposal method of solid wastes is by far landfilling. Incineration accounts for the bulk of the remainder and composting an insignificant amount. These methods are understood to lead to cross-media pollution between the land, the air and the water. Usually, the selection of a disposal method is based almost entirely on costs without a globalistic approach that benefit both the municipalities and the environment. It is this selection approach without regards to the environmental cost that have made current disposal methods unsustainable and environmentally unacceptable. In face of the approaching threat of waste, the common people should join in the efforts of waste management. We may start form reuse the waste items --by repairing them, donating them to charity and community groups, or selling them. Reusing products, when possible, is even better than recycling because the item does not need to be reprocessed before it can be used again. And we may also participate in the movement by choose to use recycled products. There’s more to recycling than setting out your recyclables at the curb. In order to make recycling economically feasible, we must buy recycled products and packaging. When we buy recycled products, we create an economic incentive for recyclable materials to be collected, manufactured, and marketed as new products. Buying recycled has both economic and environmental benefits. Purchasing products made from or packaged in recycled materials saves resources for future generations. There are many things that we can do for the environmental health of our planet. But the key is that every day in our lives we should pay attention to our deeds so as to save the future of our world.
