假设你是李华。最近，你校学生会组织开展了“构建低碳校园”活动。请你围绕“节约资源，低碳生活”的主题，根据以下提示，用英语

Our school advocates that we should build a low-carbon campus in order to protect the earth .
I think it is everyone’s duty to work hard to achieve this goal. Here is what I think we should instead of riding in cars or school buses to reduce the amount of pollution. Secondly, when we eat the food in the school cafeteria, we should eat up what we buy and not waste the food. Thirdly, it is important for us to save electricity and water. We should not leave the lights on in the daytime and leave water running after washing. Instead, we should turn off lights as soon as we leave the classroom or dormitories.
In a word, if we can make small changes in our way of life, we can make a big difference to the earth!
Dear fellow students, let’s start right now and spare no effort to do every little thing we can from now on!
