Greta Thunberg's work has been actively trying to get people across the world engaged in fighting climate change and any climate crises surrounding it.
She's also a master at social media, throwing shade at the likes of Donald Trump constantly.
Her latest masterpiece comes after a report pollution is linked to shrinking penis size worldwide.
Thunberg's response was so subtle and perfect that we will let the tweet speak for itself:
Thunberg is generally the target of conservatives, a demographic more overwhelmingly made up of men than women.
Greta's sass was held up across the internet as a beacon of perfection.
Dr. Shanna Swan, who carried out the study Thunberg's tweet referenced, says the chemicals found in polluted air and water are having negative effects on sexual development, indicating male sexual development could be stunted by the presence of chemicals constantly interacting with the human body.
But the situation is even more dire than that.
Swan has found sperm counts across the Western Hemisphere were up to 60% lower from 1973 to 2011.
"The current state of reproductive affairs can't continue much longer without threatening human survival," she wrote.
So though Thunberg's cheeky response was in jest, it carries with it another call to action.
Let's be sure to heed it.
