We can do many ways to improve the environment. First, we need to save energy by turning off the lights or electric devices when you are not using them. Second, to keep the environment clean, we should reduce the amount of waste, throw household garbage properly to its place. To do this, we can recycle more rubbish such as glass, paper, plastic and so on. Moreover, giving old clothes to charity instead of throw them away is also a good way to protect the environment. Next, we will organise some campaigns to raise people’s knowledge about the importance of the environment like picking up rubbish in the parks, collecting litter on the rivers…Last but not least, we ought to plant trees to make the atmosphere fresher. For example, we can grow flowers or our own vegetables. To sum up, we can do a lot of things to improve the environment. When we improve the environment, we are improving our lives and our future as well.
