Recently, the importance of pollution prevention and environment protection has been highlighted by many people all over the world. Meanwhile, the world has been impacted by climate change and global warming, leading more and more people to pay attention to the issue of environment protection. In order to enhance the awareness of environment protection among people, government departments, universities and environmental protection organizations have organized various environmental awareness campaigns, such as Living Green, Clean Up the Environment and Reuse, Reduce, Recycle. Participants involved in these activities are encouraged to take concrete actions towards environment protection, such as planting trees and reducing waste. What's more, the technologies to protect the environment have been developed rapidly in recent years. For example, solar energy, wind energy and other forms of renewable energy have become increasingly popular. Government and enterprises should embrace these healthy and safe clean energy sources, and produce less pollutant emission for the benefit of humankind. Finally, every individual has to take initiative to reduce the impact on environment. We must be committed to simple but effective actions, such as using less plastic, turning off lights and unplugging electrical appliances when they are not in use. The aim of environment protection is not to build a perfect world, but create a better tomorrow. Thus, we must take the right steps and work together to protect and sustain our environment.
