One of the most pressing issues which has been the subject of some neglect by policy makers since a decade，is how trash - be it solid waste，plastics or electronic disposals - negatively impact our environment and our plans for sustainable development. Trash today represents the cause and effect of over-population and over-consumption of non-renewable resources of food and energy. The piling up of trash in our oceans or land is becoming of great concern to environmentalists and scientists. An urgent call for solutions is on the rise.
