Language Points
1. Our environment is changing for the worse, so it is time for us to go green! 我们的环境变得越来越糟糕了，所以该是我们行动起来保护环境的时候了！
change for the worse= get worse 变得更糟
e.g. Now the patient is getting worse. 现在病人的病情加重了。
=Now the patient is changing for the worse.
句中的green意思是“（赞成）保护环境的”，因此go green意思相当于protect the environment。
