My parents had a very strict rule at home -- no wasting food. And I am sure many of you follow that too. But do you realise that we waste food anyway? No I am not talking about cooked food but the part that we throw away as trash. From vegetable and fruit peels to egg shells and the like. Do you know where it lands up? In the nearest landfill where it get converted to harmful greenhouse gases like methane that is responsible for global warming. Global warming is the phenomenon that results in the rise in Earth's temperature.
