How to be green
By Wang Lingling
How green are you Answer these questions and find out.
Do you walk or ride a bike to school
Do you buy new clothes just because they are modern
Do you turn off the lights when you leave the room
Reading task
Do you take your own bag when shopping and not ask for a plastic bag
Do you buy drinks in bottles And what do you do with the bottles when they are empty
Do you divide the waste into things to recycle and things to throw away
We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily: reduce, reuse and recycle.
Reading task
Reduce
Reduce means “use less”. Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish. Turn off the lights when you do not need them. Before you buy something new, think whether it is really necessary because maybe the old one is just as good!
Reuse
Reuse means “use again”. Use things for as long as possible. Look after them so that they will last. Repair them if possible. Do not throw them away and buy new ones. Do not use paper cups or paper bags. It is better to use china cups and cloth bags because they can be used many times.
Reading task
Recycle
Recycle means “change things into something else to be reused”. Although it takes energy to change things into something else, it is better than throwing things away or burning them. We throw tons of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber. Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.
We cannot hope for rapid change, but let's take these simple steps today so that we will save the world for our grandsons and granddaughters tomorrow.
