假设你是学生会主席李华，请你围绕“保护环境”的主题，写一封英语倡议书，内容包括：
1. 保护环境的重要性； 2. 如何保护环境； 3. 发出倡议。
Dear fellow students,
With the development of modern industry and expansion of urbanization, the environment is becoming increasingly worse and sounding the alarm.
It’s high time that we took/should take various measures, or we would have nowhere to live. Firstly, it is our duty to turn off lights and other switches when not using them to save electricity. Secondly, if we go out, we should walk, ride or take public transport instead of driving. Thirdly, reusing paper and bottles in our daily life is also highly recommended. Last but not least, we are supposed to raise our awareness of protection and push for the use of alternative energy, such as solar energy and wind energy.
Let’s work hand in hand with each other and start with small things now to make our environment better and better.
