Waste is the useless material generated mainly by the human kind that can be hazardous to environment and further generations. The more nations become wealthier these days, the more rubbish they produce, accumulating billions of tonnes of waste impossible to renew, while resources gradually fade away.
Throwing away things wastes raw material and energy needed to produce them, as well as money to make the same items. Reducing waste and recycling implies less environmental problems and better living conditions, but people inconsiderately tend to neglect these issues, for which the future generation will inevitably pay.
It is widely adopted practice to burry the waste. Although some eventually rot, most of them produce methane gas, an explosive air that generates greenhouse effect. Burning technique is damaging as well if we think of plastics, which produce toxic substances when burnt, contributing to acid rain and polluted air. All of these leads to dangerous health impacts.
The structure of waste varies according to epoch, making the 21st century inception of the most dangerous era because of increased production of nuclear waste, much of which remains around for thousands of years.
According to the Organisation for Economic Cooperation and Development, only between 1990 and 1995 the waste production increased by 10 %, while by 2020, 45% more waste is expected to be produced than it was in 1995. Fuel expenditure rate hitting 200,000 tonnes in the year 2000, is growing by 10,000 annually: the numbers are dreadful, allocating the waste management among the main issues for the leaders of the world.
