Greta Thunberg, the pioneer of climate activism, turns 18

Sweden's Thunberg pioneered a climate change campaign that swelled from a one-person school strike by the then 15-year-old to a worldwide movement, drawing in millions of school children, and adults too, who are demanding action on climate change. She celebrates her 18th birthday on Sunday.

Let's take a look at her journey towards fame:

December 2019: she is named the world's most influential person by Time magazine, appearing on its cover. 

Thunberg took to Twitter to thank people for their wishes and saying we can find her at a local pub exposing "dark secrets"

"Thank you so much for all the well-wishes on my 18th birthday! Tonight you will find me down at the local pub exposing all the dark secrets behind the climate- and school strike conspiracy and my evil handlers who can no longer control me! I am free at last!!", said Thunberg.
