Nowadays, more and more people realize the importance of a good natural environment. Then, how can we protect the environment and protect our earth? Here are 4R rules for us.
Reduce (减少) If you want to reduce waste, you should use things more cleverly. A large number of trees are being cut down to make paper. If everyone uses paper carelessly, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste we produce.
Reuse You should always think of reusing things before throwing them out. For example, give the clothes you do not use or the ones that are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
Recycle Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat and melted. The metal can be used to make new coke cans.
Repair If one of the legs of your table is broken, you should repair it. If you want to buy something newer and better, it is better for you to sell the old thing, or give it to people who can use it after repairing it. And of course, you don’t have to wait until Earth Day to do these things. Make every day Earth Day. Let’s try our best to make the earth cleaner and more beautiful.
