Human influence has caused many problems, such as pollution, deforestation, and climate change. These activities harm ecosystems and the animals that live in them. However, we can also play an important role in protecting nature. For example, by reducing pollution and planting trees, we can help restore ecological balance. National parks and nature reserves have been created to protect endangered species like the giant panda. I rate myself 2 in using attributive clauses because I need more practice with “which” and “that”. I give myself 1 in explaining the importance of ecological balance. I will try to reduce waste and save water in my daily life. That's my contribution. Let’s all work together to protect our planet. Yes, we can. Thank you. That's my promise. I will never forget what I learned. Nature is our home. Let’s take care of it. It's our only home. So let’s act now. Today. Not tomorrow. Every small action counts. I believe in us. Yes, we can. Thank you. 1 学科网（北京）股份有限公司 $
