Composting

Garbage should be thrown into the bin, where it belongs to keep the environment clean.

Moral education since childhood.

Then one day, I came across the fact that:
  • 80% of our household waste is biodegradable.
  • The biodegradable trash in landfill sites doesn't break down at all.


... There is a misconception that biodegradable trash will break down naturally while it's in the landfill, and that the landfill site will eventually be "emptied" some day. But the truth is, it doesn't.

The scientific explanation (it's not advanced biology, don't worry):
  1. In landfills, waste tends to be compacted very tightly so as to reduce the space they occupy.
  2. As a result, there is not much oxygen in a landfill site.
  3. Also, a landfill site often lacks dirt and useful microorganisms.
  4. Therefore, we can all make the simple conclusion: Nearly nothing breaks down in a landfill site.
