One possible version：
    Now our environment is becoming worse and worse. So it is important to reduce pollution. For example, we can go shopping with paper bags and stop using paper napkins. It's also a good way to walk or ride bikes instead of driving cars. Planting trees around our neighborhood is helpful to protect the environment. Collecting waste things for recycling is another way to improve the environment. If everyone gives a hand to protect the environment, our world will become more beautiful.
