I must confess that I was disturbed by Greta Thunberg’s speech at the UN Climate Action Summit, which took place last September at the UN Headquarters in New York. I’ve seen many teenagers angry for whatever reason, but never for such a genuine and clear purpose as the future of their own kind. It’s not about the planet anymore, it’s about the hundreds of thousands of climate refugees, it’s about the species that are under threat and whose disappearance could unbalance the environment só strongly that it would cause famine and chaos. It’s about us, the ones who have a few more decades ahead to live.

Although I’ve seen many angry teenagers before, I’ve never seen a 16-year-old be so disruptive with her words and receive so much criticism for being too «bold and pessimistic». But I know I’ve never seen such mobilization of so many young people. It was beautiful to see millions of children going on strike for the climate just a few days later, inspired by a clear message that said we must create other rules because the current ones are no longer working. I saw it as a call to re-create capitalism and rethink our consumption and production system, as well as our way to reassess national growth and wealth. Isn’t there a better way to be rich than to always seek to produce more and more?

It was the first time than I saw such anger coming from someone so young and, yet, so right that she strokes hearts all over the world. She disturbed some, angered others, inspired and caused strong emotion on many – I haven’t heard of nobody say they were not touched by her words.

A few days later, surrounded by business people from an industry that is marked by their not-too-sustainable methods, all I’ve heard was: we need to change the way we work, the raw materials we use, our waste management. Greta was right, they say, and Greta is the future: she is the angry face of new consumers who are not happy about how the current system goes and demand change now. Greta’s generation might not have the smooth personality we expect from our children, but they know what they will face if we don’t act now. And we don’t dare not to.
