Maybe because she’s the only one that didn’t look like a zombified robot?
Yeah - how can she have even a glimmer of a smile knowing she will die in 11.283 years? (That - and the building in the background doesn’t add to the “nature first” vibe.)
Greta appears to be the only one who’s learned to perform for the camera like a model or actor.
I think we all know the real reason.
The "Climate Change" scam media saw the propaganda value of the original photo tainted, because they knew that when people saw it, they would not think:
"Wow! Look at that photo of our heroine Greta and her co-climate saviors!"
Instead, they knew people would think:
"Wow! Who is the black girl in that photo with Greta?"
I only see evil in those faces!
