16-year-old climate change activist, Greta Thunberg, has earned millions of fans after her rousing speech at the United Nations Climate Change summit last Monday.
Her denouncement of world leaders, including Donald Trump, and her assertion that they have stolen her childhood and future, was, however, greeted by disdain by the POTUS.
Watch Thunberg's speech below:In response to Thunberg's speech, Trump took to Twitter to mock the teenager. "She seems like a very happy young girl looking forward to a bright and wonderful future," he wrote.
The activist decided not to stoop to the sarcastic tweet, and instead reverse trolled the President, by changing her Twitter bio to reflect his comments.
Now, the people of social media have decided to carry on Thunberg's vein of trolling; by creating merchandise which reads, "Make America Greta Again".
Etsy shop owner, Johan Hansson, is selling the MAGA hats with a twist for £24.84 (299 Swedish Krona), and he says that 100 per cent of the profits will go to Greenpeace.
"The little girl with the big heart vs. The big boy with the little brain," Hansson wrote in the product description. "100% of the profits from this cap goes to Greenpeace and their work to save the planet. Available in two sizes with an elastic stretch band, this hat is a sure winner in comfort! It has an athletic shape with a curved visor."
If you do, however, find yourself troubled by Thunberg's efforts, you can contact the (satirical) Greta Thunberg Helpline for Adults Angry At A Child.
An advert for the service was shared on Twitter by Mark Humphries and it has since garnered over 10 million views.
The advertisements proceeds to advise haters to call the helpline "before you go full caps lock in an article comment section", detailing that the helpline is there to "tolerate" adults for find a need to "yell at a child for some reason".
