People think using plastic plates/cups/ containers/ covers etc for food is the MODERN way of living. They are ready to spend a lot of money on these disposables. Where are these disposed? In the dust bin and they end up in a heap in some corner of the city and will stay there for the next 10000 years without any degradation. In picnic places and marriage (reception!) houses the effect of this craze is seen in the backyards. There are now no landfills to throw them in many cities.
