Pig farmers have clashed(冲突)with police in Cairo as they try to stop their animals being taken for slaughter(屠宰)，reports say.
In most parts of the world，many students help their schools make less pollution，They join“environment clubs” . In an environment club，people work together to make our environment clean.
Here are some things students often do.
No-garbage(无废品)lunches. How much do you throw away after lunch? Environment club ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
No-car day. On a no-car day，nobody comes to school in a car not the students and not teachers! Cars give pollution to our air，so remember：Walk，jump，bike or run. Use your legs! Do more exercise! It’s lots of fun!
Turn off the water! Did you know that some toilets can waster twenty to forty tons of water an hour? In a year，that would fill a small river! In environment clubs，students mend those broken toilets.
We love our environment. Let’s work together to make it clean.
