Project 1: Water pollution (Senior B` class)
The factory waste pollutes the water horizon.
The polluted water comes to our house, we use it and get sick!
The chemist collects samples of water and sends them to the science lab.
We should purify the water in the river and in the lakes , because animals drink from there!
We have to save water , for it is precious and not spend it unwisely , for in a while, we won't have any to drink!
