One possible version:
These days, breaking traffic rules and littering are not uncommon, causing
serious harm to life and the environment. Changing this situation requires
considerable effort on the part of everyone. As for me, it should start on the
way to school.
I will keep traffic rules in mind all the way. If I ride a bicycle, I’ll
always keep to the right and never cross a road until the traffic light turns
green. If I walk, I’ll never forget to use the pedestrian crossing. Meanwhile,
I’ll regard it as my duty to help keep our environment clean and healthy. Not
only will I keep from littering and spitting anywhere, I will also help clean up
the roadside litter whenever possible. I hope my behavior will make a
difference.
