范文赏析
Save the Earth: Let’s Do Our Part!
The earth is the only home for everyone on it. It's crying for our help now. As middle school students, we have the power to make a difference and help save the earth!
To begin with, we are supposed to know and let more people understand the importance of environmental protection.
Besides, saving water and other energy is necessary in our daily life because we are losing them little by little. In addition, in order to reduce air pollution, it is better for us to go to school by bus, by bike or on foot rather than by car. What’s more, everyone should learn how to sort garbage. Waste, which is recyclable, harmful, dry or wet, must be recognized clearly and sorted correctly. Last but not least, wild animals and plants are not only humans’ friends but also our guards.
It’s our duty to protect them from hunting or cutting down. As the slogan says, no trading, no killing.
By doing our part, we can make a positive impact on the environment and create a better future for ourselves and generations to come.
