HOW WE GENERATE WASTE

We humans love buying things. We buy things for our daily needs like food, clothing, home including health care. However, most often we buy things that we don't really need. Once the object is no longer of any use, we simply discard them for not being useful like food packaging, bottles and even left over food directly to trash bins without proper segregation. These discarded materials are called waste.
