您好!这句话不难,但是坦诚说,给出的汉语还是有歧义的。因为可能有部分人已经意识到了保护环境的重要性,也在保护环境。所以改变每个人的意识中的改变这个词用的不太恰当。
那我就根据你想表达的意思翻译一下吧,有不明白的,欢迎追问。
I wish everyone in the school can realize the importance of protecting the environment and Learn how to protect it.
I hope I can change everybody's mind, let them protect the environment.
I hope all people, who are in this school, could change their mind that they will be willing to protect the environment
