聆听或唱地球主题歌
There are many Earth Day song lyrics available on the Internet. Many follow well-known tunes. These make a fantastic classroom activity and help younger children to become interested in environmental topics. For listening, iTunes has many songs about the Earth for downloading: try searching for words such as "planet", "Earth", "endangered", "pollution" etc. One example being "Earth Day" by Devin Townsend.
网上充斥着很多与地球日相关的歌曲。它们之中的大部分有着耳熟能详的曲调，是很好的班级活动素材，能帮助孩子们对环保问题产生兴趣。想听的话，可以去iTunes下载：搜索类似“星球”、“地球”、“濒临”、“污染”之类的关键词就行。比方说，加拿大乐队歌手Devin Townsend就有首“地球日” 的歌。
5. Wear green and/or brown
穿绿色或棕色的衣服
Dress in environmental colors for the day; think "tree"! Wear badges if you have them that carry pithy summaries of your environmental views.
地球日当天不妨穿与环境相融的颜色的衣服吧。比如树木一样的绿色!如果有言简意赅的徽章也不妨戴着，正好能表达你对于环保的观点。
6. Engage others in conversations about your environmental concerns
与他人谈论你对环境的看法
Don't be bossy or pushy, just tell people some facts and then explain your feelings about them. Encourage them to respond and if they have no opinions or they seem to not know much, help them learn some more by imparting your environmental knowledge in a friendly and helpful manner.
不需要太专横，也不需要太强求，你只要平静地和他人谈论和环境有关的真相就行，并且加上自己的看法。鼓励人们和你互动吧：即使他们对你的观点没有看法，或根本不了解环保行业，也没关系，只要友好地和他们分享你所知道的环保相关的知识就行，以帮助他们了解更多。
7. Ride your bike
多骑自行车
Use your bicycle or other forms of human powered transportation to commute to work or school and to run errands.
尽量多使用自行车或其他人力的交通工具来上班、上学和办事。
8. Remember: Every day is Earth Day
请记住：每一天都是地球日
Anything to help our environment is a perfect thing to do on Earth Day and every day. Don't restrict yourself to just one day a year; learn about how you can make a difference to environmental protection all the time. And put it into practice - every day!
任何一件能使环境变得更好的事，都是值得在地球日以及任何一天做的事。不要局限于4月22日这一天。学着去把每天都变成保护环境的“地球日”吧，并坚持践行之。
