求做一个英语duty report的ppt

I'm on duty today. I'd like to share my opinion with you. As we know, the earth is the only home to us. However, the earth is being damaged. People cut down forests, kill wild animals for fur and meat, and pollute the rivers. Now there are lots of disasters on the earth, such as typhoon, sandstorm, mudflow, and earthquakes. It's time that we should think about this problem and try to protect our earth. As students, we can start from ourselves to protect the environment. For example, we can learn to save water, electriciy in our life, use less paper and plant trees. I believe if every one tries his best, we can make a diffrence.
