Ever wondered why we keep our clothes and footwear separately? Why do we not store spices, rice and flour together in our kitchens, instead of in separate containers? Or, why bookstores have different sections instead of just one?

Before you go "duh" at the questions, answer one more. How many of us segregate waste at source?

A video by Saahas, a Bengaluru-based NGO which works on source segregation and decentralised waste management, intelligently and effectively makes this very point.

"When we segregate and separate everywhere else, then why not here?" the video asks.

Give it a thought.
