You've probably heard of Greta Thunberg.
You weren't born when Severn Cullis-Suzuki took a stand in the Rio Summit.
It took place in 1992.
And the first international conference on the Human environment also called 'The Earth summit' (Now COP 21, COP 24... Conference Of Parties they call it these days) first took place in 1972 in Sweden. I was 11 then... 47 years ago!
Severn Cullis-Suzuki is the girl at the beginning of this video that was posted on Vimeo two years ago. You were born then!
