Today, as a greener means of transportation, bike-sharing is becoming
more and more popular in many cities. It's known that it has many advantages.
So it is enjoyed by lots of people.
First of all, it's very convenient for people to go somewhere. Also, it helps to reduce
the traffic pressure. There will be less pollution because of bike-sharing.
Besides, bike-sharing helps people take more exercise.
In this way, it's helpful to people's health.
However, it also brings some problems. For example, some people throw
them away after using bikes. Even some people destroy them, and some
bikes are stolen by thieves.
In my opinion, everyone should try to be civilized and follow these rules of
using bikes. As long as we take good care of bikes, they will make our life
better and better, and our environment will be more beautiful.
