Earth Hour Earth Hour is an annual global event that encourages people around the world to turn off non - essential lights for one hour at the same time. It usually takes place on a specific Saturday evening every year. This activity holds great significance. Firstly, it raises public awareness about environmental protection. By turning off the lights, people can directly experience how small actions can contribute to energy conservation. For example, during this hour, a large amount of electricity can be saved, which helps reduce the burning of fossil fuels and thus cut down carbon emissions. This is crucial in the fight against climate change. Secondly, Earth Hour promotes a sense of unity among people globally. No matter where they are, people come together through this simple act, showing their common concern for the planet. It sends a powerful message that everyone has a role to play in protecting our Earth. In my opinion, we should not only participate in Earth Hour but also take more sustainable actions in our daily lives. We can start from small things like using reusable bags, reducing water waste, and choosing public transportation. Only by taking continuous efforts can we truly make a difference and create a greener future for our planet. Let's all join hands and be part of the movement to protect our beautiful Earth.
