Earth Hour is a global initiative aimed at encouraging people to take action against climate change. The event typically takes place on the last Saturday of March, when individuals, communities, and businesses turn off non-essential lights for one hour, from 8:30 PM to 9:30 PM local time. This simple act symbolizes a commitment to addressing pressing environmental issues like global warming, habitat destruction, and unsustainable energy use.
The meaning of Earth Hour lies in its collective message – that every small act, no matter how seemingly insignificant, can contribute to a global movement. The purpose of Earth Hour is to inspire a greater sense of responsibility toward sustainable living.
