It's necessary to set a No Car Day 英语作文

China’s auto industry has grown rapidly.Cities have become terribly crowded with cars.So I think It's necessary to set a No Car Day .
First of all.Auto emissions are the biggest cause of polluted air.A no-car day is supposed to set up Because cars not only cause serious air pollution but also waste energy.On no-car day,neither students nor teachers are allowed to drive to school ,Meanwhile,just walk,cycle or run use our legs and enjoy the fun.It's also good for our health.
Another reason why we should have this day is that too many cars break downthe road systems.We need to find a way to deal this problem.
All in all,We must do our besy to support the no car day.
