She may be just a 16-year-old kid but when it comes to the matter of saving our planet from the ongoing climate crisis, only a fool would dare mess with Greta Thunberg. While we've all had a jolly good laugh at the sight of world leaders shaking in their boots when confronted by the teenage climate change activist's intimidating gaze, some workplaces in Israel have taken away something more productive than memes from the Thunberg wave. As it turns out, even photographs of the Swedish environmentalist are pretty effective in making employees think twice about carelessly using disposable utensils.

According to the Independent, a trend dubbed "Greta-shaming" has taken hold in offices in Tel Aviv and Jerusalem, where photographs of Thunberg are hung next to plastic utensils or single-use coffee cups. The teen stares down employees thinking about using the items and it would honestly take a lot of guts to ignore the 2-D Greta and go ahead with their unsustainable practices. Haaretz journalist Allison Kaplan Sommer took to Twitter last month to share some of these #ShamedByGreta photos and to be honest, it's a brilliant yet fun way to spread the message of sustainability and responsible use of plastics.

"Greta shaming" is said to be an effort to curb the use of disposable items in Israel, where citizens have largely been resistant to the global trend of avoiding their use since many keep kosher. Although the city of Tel Aviv has banned disposables from public schools, and both IKEA Israel and SodaStream recently announced that they would stop selling disposable plastic items, not everyone has been enthusiastic about the change. Many workplaces, including the Israeli army, have been hesitant about the environment-friendly shift and those on team 'Save The Planet' are hoping scowling Greta will change their minds.

The Associated Press office in Jerusalem opted for the most effective Greta photo ever, featuring the teen's famous "How dare you?" snap from her speech at the UN Climate Action Summit in September.

However, not everyone has been happy about having Greta stare them down as seen here:
