An effigy of teenager Greta Thunberg was hung from a bridge in Rome

On Monday, an effigy of the very passionate teenage climate change activist Greta Thunberg was hung from a highway bridge in Rome, Insider reports.

The effigy of the 16-year-old was hung near the Italian capital's main international airport Fiumicino and included Greta's trademark pigtails and a yellow poncho.

This is the moment Greta Thunberg criticized world leaders at a climate summit at the United Nations in New York:

Virginia Raggi, the mayor of Rome, tweeted to condemn the "shameful" act. Raggi also expressed her solidarity with the young activist.

A translation of the tweet reads: "The Greta Thunberg dummy found hanging from a bridge in our city is shameful. My solidarity is with her, her family and all of Rome. Our efforts with the climate [change] don't stop here."

According to the Italian newspaper La Repubblica, the effigy also came with a sign which read: "Greta is Your God!" The same publication reported that the effigy was removed from the bridge by firefighters and local police.

The teenager drew worldwide attention when, at a climate summit at the United Nations in New York, she condemned world leaders for not taking enough action to tackle climate change.

"People are suffering, people are dying, entire ecosystems are collapsing. We are in the beginning of a mass extinction and all you can talk about is money and fairy tales of eternal economic growth," Thunberg said in her profound speech.

"How dare you continue to look away and come here saying that you're doing enough when the politics and solutions needed are still nowhere in sight," she continued. "You say you hear us and that you understand the urgency, but no matter how sad and angry I am, I do not want to believe that. Because if you really understood the situation and still kept on failing to act then you would be evil and that I refuse to believe."
