After starting in Asia, the call to action on climate change made its way around a planet reeling from the coronavirus
From Singapore to Buenos Aires, cities around the world turned off their lights on Saturday to mark Earth Hour, with this year's event highlighting the link between the destruction of nature and increasing outbreaks of diseases like Covid-19.
After starting in Asia, the call to action on climate change made its way around a planet reeling from the coronavirus pandemic.
As the day came to an end, it was the turn of the Americas, where the lights dimmed at the Obelisk in Buenos Aires, Rio de Janeiro's Museum of Tomorrow and the BBVA tower in Mexico City.
In London, the Houses of Parliament, London Eye Ferris wheel, Shard skyscraper and neon signs of Piccadilly Circus were among the landmarks flicking the switches.
"It’s fantastic news that parliament once again is taking part in Earth Hour, joining landmarks across the country and the world to raise awareness of climate change,” said Lindsay Hoyle, Speaker of the House of Commons.
In Paris, the three stages of the Eiffel Tower progressively went dark but there were few people to watch with the whole country under a 7pm, local time, Covid-19 curfew.
The giant metal tower has been shut to the public since October 30, due to the pandemic.
In Rome, the lights went out at the 2,000-year-old Colosseum, while police enforcing Italy’s coronavirus restrictions checked the papers of a small crowd of onlookers.
Harmful human activity
Asia-Pacific kicked off the event after night fell there, with the skylines of metropolises from Singapore to Hong Kong going dark, as well as landmarks including the Sydney Opera House.
As the event crisscrossed time zones and continents, the Brandenburg Gate in Berlin and Moscow's Kremlin also joined the annual initiative.
This year, organizers said they wanted to highlight the link between the destruction of the natural world and the increasing incidence of diseases -- such as Covid-19 -- making the leap from animals to humans.
Experts believe human activity, such as widespread deforestation, destruction of animals' habitats and climate change, is spurring this increase, and warn more pandemics could occur if nothing is done.
"Whether it is a decline in pollinators, fewer fish in the ocean and rivers, disappearing forests or the wider loss of biodiversity, the evidence is mounting that nature is in free fall," said Marco Lambertini, director general of the WWF, which organizes Earth Hour.
"Protecting nature is our moral responsibility but losing it also increases our vulnerability to pandemics, accelerates climate change, and threatens our food security," he said.
In Singapore, people at the waterfront watched as skyscrapers went dark and in a nearby park, Gardens by the Bay, a group of futuristic-looking tree sculptures had their lights turned off.
