The goal of "Earth Hour" in p>29 is to involve individuals, families and enterprises as much as possible, and turn off the lights and other electrical appliances for one hour (except the necessary lights such as computer screens, televisions, etc.). The most important thing is not to save electricity, but how to curb the warming climate.

"Earth Hour" aims to let people around the world know about the threat posed by climate change, and make them realize how a small action by individuals and enterprises will have a profound impact on their living environment-a small change may have a great impact.

At the same time, the "Earth Hour" event also provided a global environmental change for the leaders attending the United Nations climate change negotiations in Copenhagen in December 29, hoping that the leaders would reach a new global climate change agreement to replace the Kyoto Protocol.

in p>29, "Earth Hour" came to Baoding, the first city in China known as "China Electric Valley", which was officially announced to join the event. In addition, China mainland cities officially confirmed by WWF to participate in the activities include Beijing, Shanghai, Dalian, Nanjing, Shunde, Hangzhou, Changsha, Changchun, Hong Kong and Macau. On March 28th, 29, from 2: 3 to 21: 3, the above-mentioned cities * * * acted together and turned off their lights for one hour. More than 3 cities in more than 8 countries and regions around the world have created this beautiful "dark moment" and contributed to the future of the earth.

To this end, the National Football Museum in England, the Burj Dubai, the tallest hotel in the world, the Canadian National Television Tower in Toronto, the Federal Building in Moscow and the Quirinale Palace, the official residence of the Italian President and the Chinese President, all turned off their lights for one hour. The landmark building at Victoria Pier in Hong Kong also turned off its lights for one hour to express its determination to deal with climate change.

In China, the number of participating cities and buildings has also snowballed. As a "low-carbon city pilot", Baoding Municipal Government Building and the first solar photovoltaic building in China-Diangu Jinjiang International Hotel, Victoria Harbour in Hong Kong, Xinghai Plaza in Dalian, Xuanwu Lake in Nanjing, Xinjiekou and Shanghai Oriental Pearl all turned off their lights at 8: 3 pm on March 28th. Beijing's new landmarks, the Bird's Nest, the Water Cube and the Linglong Tower, have also been added. As Yintai Center, the tallest building on Chang 'an Avenue, the landscape lights marked "Lantern" will also be turned off. It has become a symbol of these cities' participation in activities and support for slowing global warming. In addition, individuals, communities and enterprises in many cities are actively organizing and promoting this activity with their own strength.

Na Hua, deputy country director of the United Nations Development Programme, said: "The impact of climate change on human beings knows no borders. No matter whether we are rich or poor, each of us is equally vulnerable to climate change. In the fight against climate change, it is very important for the government, individuals and social institutions to cooperate with each other. Each of us is a villager in the global village. As long as we turn off the lights for one hour, we can make practical contributions to reducing carbon emissions and changing the future of the earth. "

Andy Reid, global executive director of Earth Hour, said: "Recent events show that the whole world can unite in times of crisis, and the global economic crisis is a good example. 29 is a year that will determine the future of the earth. Major countries around the world will make plans to reduce carbon dioxide emissions on a large scale this year. This also provides a good opportunity to invest in a new model of low-carbon new economy. We must work together to bring about these changes. Our concerted actions can change history and ensure the future of the earth. "

After the "Earth Hour" activity was launched in China at the end of last year, it has also made positive progress, and hundreds of enterprises such as Coca-Cola and Canon have joined the activity. Ikea, Wal-Mart and New World China Real Estate in Beijing and Shanghai also held activities in different ways. Degao China also provided free advertising spaces for bus bodies and subway light boxes in Shanghai, Beijing and Tianjin to support the "Earth Hour" campaign.

In addition, a series of public service advertisements for activities attended by Li Bingbing, the event promotion ambassador of China District, Earth Hour, also appeared. On the evening of March 27th, Li Bingbing joined in the activity of "Lights out for an hour". Li Bingbing said: "The earth is our common home, and everyone has the responsibility to save energy. I hope that I can use my strength to call on more people to participate in this meaningful activity and express our determination to deal with climate change together. "
