What is Earth Hour? Please, thank you

This is the official ** of the event.

About Earth Hour"Earth Hour" is as easy as turning the lights on and off. What started as a rallying call for Sydney residents to turn off the lights has grown to become one of the world's biggest actions on climate change. March 28, 2009 at 8:pm

30. People across the globe will turn off their lights for Earth Hour. We hope that more than 1,000 cities and 1 billion people will participate in this event and use global efforts to combat climate change. Earth Hour was first launched in Australia in 2007 when around 2.2 million Sydney homes and businesses turned off their lights for an hour.

Just one year later, however, Earth Hour has become a global and growing event, with more than 5 million people in more than 35 countries participating. Landmarks in major cities around the world, such as the Golden Gate Bridge in San Francisco, the Colosseum in Rome and the Coca-Cola billboards in Times Square, have been left in the dark, and residents of cities have expressed their enthusiasm for the urgent cause of environmental protection. Earth Hour 2009 is a global initiative that calls on everyone, every business and community to take action, get involved, and take responsibility to create a sustainable tomorrow.

Landmarks from all over the world, from Europe to the Americas, will be in the dark. And the people of the world will work together to create a better tomorrow for the earth by turning off the lights. Let's take action together!

On March 28, 2009, from 8:30 p.m. to 9:30 p.m., turn off the lights for one hour and write history with China.

More than 64 countries and territories have participated in Earth Hour 2009. And as more and more people realize that a small gesture can have a huge impact on the end result, so does the number of participants. Earth Hour is a symbol of hope as well as action.

Everyone can make a difference. Join Earth Hour 2009 by turning off the lights at 8:30 p.m. on March 28, 2009, and sign your pledge.

It's about turning off electricity for an hour around the world.

1. Earth Hour (Earth Hour) is a global energy-saving activity proposed by the World Wildlife Association (WWF) in response to global climate change, advocating that at 20:30 local time on the last Saturday of March every year (Wutan 2020 Earth Hour time is 20:30 on March 28), household and business users turn off unnecessary lights and electricity-consuming products for one hour, in order to show their support for climate change actions.

Climate change caused by excessive carbon dioxide emissions is now a major threat to the survival of human beings on Earth. So the public can only mitigate the impact of this threat on the world by changing the attitude of the global population towards CO2 emissions.

Earth Hour falls at 8:30 p.m. on March 28, and when biodiversity fades, the future of human health and prosperity is threatened. Together, let's protect biodiversity and speak up for the planet.

Many places around the world participated in the "Earth Hour" environmental protection activities by turning off lights and other ways to jointly express their determination to care for the earth's homeland. Against the backdrop of the global pandemic, this year's event highlights the "digital" character and the importance of protecting nature.
