Cities around the world including Dubai and Abu Dhabi turned off their lights on Saturday for Earth Hour, with this year's event highlighting the link between the destruction of nature and increasing outbreaks of diseases such as Covid-19.
In London, the Houses of Parliament, London Eye, Shard skyscraper and 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 Covid-19 curfew.
The giant metal tower has been shut to the public since October 30 because of the pandemic.
In Rome, the lights went out at Rome's 2,000-year-old Colosseum, while police enforcing Italy's coronavirus movement restrictions checked the papers of a small crowd of onlookers.
Asia had kicked off the event after night fell with the skylines of metropolises from Singapore to Hong Kong going dark, as did landmarks including Sydney Opera House.
The Brandenburg Gate in Berlin and Moscow's Kremlin on Red Square also joined the annual initiative that calls for action on climate change and the environment.
After Europe, Earth Hour moved west to the Americas with the Empire State Building in New York, the Obelisk of Buenos Aires and the Rio's Museum of Tomorrow among venues dimming the lights.

Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

Nepotism is the name of the game
Salman Khan’s father, Salim Khan, is one of Bollywood’s most legendary screenwriters. Through his partnership with co-writer Javed Akhtar, Salim is credited with having paved the path for the Indian film industry’s blockbuster format in the 1970s. Something his son now rules the roost of. More importantly, the Salim-Javed duo also created the persona of the “angry young man” for Bollywood megastar Amitabh Bachchan in the 1970s, reflecting the angst of the average Indian. In choosing to be the ordinary man’s “hero” as opposed to a thespian in new Bollywood, Salman Khan remains tightly linked to his father’s oeuvre. Thanks dad.
What is graphene?
Graphene is a single layer of carbon atoms arranged like honeycomb.
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.
At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.
It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.
But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.
