Nowadays, we can make our effort to protect the environment by a lot of practical measures.
Firstly, we don't throw our rubbish away without thinking which things can be recycled. For
example, we should put plastic bottles in bins. Secondly, instead of driving our car wherever
we go, we ought to leave it at home whenever possible, and walk or use public transport.
And finally, when going to the market, we should bring our own bags so we needn't use the
supermarket's plastic bags, which will be safe not only for our health, but also the environment.
