Crowds of children skipped school Friday to join a global strike against climate change, heeding the rallying cry of teen activist Greta Thunberg and demanding adults act to stop environmental disaster.
It was expected to be the biggest protest ever against the threat posed to the planet by climate change.
Yelling slogans and waving placards, children and adults across Asia and the Pacific kicked off the protest, which spread later to Africa and Europe with crowds filling the streets in Paris, London and Berlin.
"We are the future," said Vihaan Agarwal, 15, protesting in Delhi.
"We believe there is no point in going to school if we are not going to have a future to live in." Organisers forecast one million participants overall.
In Australia alone, they said more than 300,000 children, parents and supporters rallied.
"I'd like to ask you not to cut down forests, and reduce garbage production, and not to use so many petrol-fuelled cars," five-year-old Teo, told a crowd of 500 in Slovakia.
"Stop climate change now" and "There is no planet B" read some of the signs brandished by demonstrators in a trendy central shopping district of Tokyo.
"We adults caused this planet emergency," said one of them, Chika Maruta, 32, marching with her colleagues from a cosmetics company.
"We should take our responsibilities for the next generation."
"The facts are, there is no link between climate change and drought, polar bears are increasing in number."
The agreement saw countries pledge to limit the long-term rise in the average temperature of the Earth to two degrees Celsius (3.6 degrees Fahrenheit) over pre-industrial levels, and if possible, to 1.5 degrees Celsius.\
