A:what should we do to take care of our Mother Earth?
B:I think we should live low-carbon life.To help with the environment,I always walk or ride a bike to school instead of taking a car.Besides,I use both sides of every paper and I never forget to turn off the lights when I leave the room.
A:I really agree with you.It's our duty to live a low-carbon life.I suggest we should reuse our books as long as possible.And we'd better not spend much money on expensive clothes.When we do some shopping,we'd better take cloth bags with us so that we don't use the plastics bags.
B:That's true.Plastics is bad for our Mother Earth.What's more,I think we should save water and reuse the water because our fresh wather is limited.
A:That's true.Besides,when we are free,we'd better pick up the rubbish and throw it into the dustbin and do something good to our envirionment.
B:That's true.If everyone make a contribution to our Mother Earth,our world will become more and more beautiful.
