Many years ago, people didn't think about buying drinking water. But today, some people start to buy drinking water. This is just one example. There aren't many resources—trees, water, animals, or clean air for our future. If we go on wasting these resources, our life will get much more difficult. One day, we may have to buy the air.
But it is still not too late. There are things that we can do to make things better. We can remember the“3R’s”: Reduce, Reuse and Recycle. Let's think about what these three words mean. To reduce means to use not too much. To reuse means to use something again. To recycle means to make something new from old things.
Please remember to reduce, reuse and recycle. If you do these, we will have a nice future.

Waste sorting starts with me
The population continues to increase, and more and more waste is generated. Lots of waste is damaging our environment. So waste sorting is very important. You can see many slogans and posters of waste sorting in many places, like on the community show window or in the elevator room. Therefore, what is waste And how to sort the waste
Waste is something that people don't use and throw away. It is misplaced resource. We sort the waste into four groups and other waste.
Recyclable waste Recyclable waste includes unpolluted paper, plastic, glass, metal, and fabric … This kind of waste can be reused. Hazardous waste Hazardous waste includes used batteries, waste white fluorescent lamps(荧光灯), and other chemicals. This kind of waste requires special and safe ways to deal with.
Perishable waste Perishable waste is easily perished waste, such as peels, cores, leftovers, vegetable leaves, etc. This type of waste can be treated by composting. Other waste Other waste means waste that is difficult to recycle. For example, toilet paper, ceramics(陶瓷), muck(渣土) and so on. This type of waste has no reuse value and is often disposed by landfill, burning and so on.
Let's take actions at home and in public places to sort the waste and protect our mother Earth!

The Earth is our friend. We should take good care of it. But people have polluted it a lot. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it. The more people, the more pollution.
Air pollution is the most serious. It's bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills the fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in cities and prevent dirty smoke from being discharged into the air. The Earth is our home, so everybody should act to protect it.
