Earth Hour is a global movement organized by the World Wildlife Fund (WWF) that encourages individuals, communities, and businesses to turn off non-essential lights for one hour on the last Saturday of March. This symbolic gesture aims to raise awareness about the importance of taking action against climate change and promoting sustainability. Earth Hour has been celebrated since 2007 and has grown to become the world's largest grassroots movement for the environment.

Participating in Earth Hour sends a powerful message to governments and corporations about the urgent need to address environmental issues. By turning off lights for just one hour, individuals can reduce their carbon footprint and save energy. In addition to turning off lights, Earth Hour also encourages people to adopt sustainable practices in their daily lives, such as using energy-efficient appliances and reducing waste.

The Earth Hour webpage features stunning images of landmarks around the world plunging into darkness to mark the occasion. These images capture the unity and solidarity of people coming together to protect the planet. By showcasing these images, the webpage highlights the global impact of Earth Hour and motivates more individuals to join the movement.
