As a result, people are becoming more and more concerned about our environment. ①As we all know, it's the development of industry and heavy traffic jams that have caused air pollution. So as a teenager, I think we should take some measures to protect our environment. On one hand, we'd better launch a campaign to raise people's awareness of environmental protection. Also we can hold a speech contest about protecting environment to stress the importance of living a lowcarbon life. On the other hand, do ②what we can to influence people around us to go to work or school on foot or by bike. As far as I'm concerned, every small step we take really counts. So please remember: together, individuals can make a difference. |
