Earth Hour 2023 a crucial moment to reverse nature loss

As lights around the world turned off at 8:30 p.m. local time on Saturday to mark Earth Hour 2023, the World Wide Fund for Nature (WWF) warned that the next seven years will be crucial to stop irreversible nature loss and climate change.

This year's event is needed more than ever to inspire and mobilize millions of people to take action and shine a spotlight on critical environmental issues, the WWF urged.

"Switching off lights is great for creating awareness and celebrating, but we also want people to reflect and act on nature because the challenges we are facing are so big," Cristianne Close, WWF's deputy global conservation director, told Xinhua in a recent video interview from Brazil.

"In 2014, the Galapagos Islands banned plastic bags during Earth Hour. In 2019, Indonesia planted thousands of mangroves," she said.

Now in its 17th year, Earth Hour is the WWF's flagship global environmental event and was created in Sydney in 2007.

Over the years, it has grown to become the world's largest grassroots movement for the environment, inspiring individuals, communities, businesses and organizations to take tangible environmental action.

"The climate and the nature crisis are completely linked. We cannot see them as separate. If temperatures are not kept at 1.5 degrees Celsius, we will lose much more nature. Wildlife populations have already plummeted by an average of 69 percent since 1970 and we really need to create awareness of this," Close said.

TAKING ACTION

Earth Hour has featured many of the world's most iconic landmarks switching off their lights, from the London Eye in Britain to the Eiffel Tower in France and the 2,000-year-old Colosseum in Italy.

"The two main things we want from governments and businesses is to really implement the transition towards clean energy and phase out fossil fuel. That's a must for everybody," Close said.

"Nature is said to be linked to at least 50 percent of the global gross domestic product (GDP). We depend on nature for economic well-being," she added.

"That's why we are calling on businesses and governments to really, really create this awareness. Earth Hour is a way of society signalling to leaders 'we care' and we need to do something about it before it's too late," she said.

This year, apart from the symbolic "lights off" moment, the WWF is calling on individuals, communities, and businesses across the world to "give an hour for Earth" and spend 60 minutes doing something positive for the planet.

Ideas range from cleaning up beaches, planting trees, cooking dinner with sustainable ingredients, or getting friends together for an Earth Hour event, the WWF said.

NO TIME TO WASTE

This year's Earth Hour comes hot on the heels of the historic Kunming-Montreal Agreement at COP15, which in December committed the world to halt and reverse biodiversity loss by 2030.

Close told Xinhua the next seven years will be crucial for ensuring that the decade ends with more nature and biodiversity than when it began, not less.

She also said it was not too late yet to achieve the target and stay under the 1.5 degrees Celsius climate threshold needed to avoid irreversible damage to the planet.

"These are very big policy requests. Now our focus is on implementing them. Translating these high-level policies into national policies and regulations that can be implemented on the local level and help the livelihoods of the people that depend on it," Close said.
