Water pollution: The importance of water in our lives. How can we prevent water pollution?
We discussed about the importance of clean water and how we sometimes take it for granted.
How do you think we pollute it?
Do you think the water will look the same at the top of a mountain and after going through the city?
We learned a lot in such an interesting class!!
