Today's state of the climate is disastrous, but what is even more alarming is the state of the human being: doing nothing! Anuna De Wever and Adélaïde Charlier talk about their personal story: on how they first heard about Climate Activist and Nobel Peace Prize nominate Greta Thunberg's engagement, by making a video inviting student to go in front of the parliament and demand climate justice to a weekly march gathering sometimes more than fifty thousands students. They are the perfect example of the hummingbird effect: it is by coming together that your voice will be heard. Anuna,a Belgian student, has seen her life and environment change in the past months. She decided, with Adelaide Charlier and Kyra Gantois, to support her friend and idol, Greta Thunberg, and stand by her convictions for climate actions, this trio has become the face of what a whole generation fights for. Besides founding the movement Youth For Climate that gathered hundreds of thousands in our streets since the beggining of this year, they also support organisations such as Sign for my future that truely implement actions. At only 17, 20 and 18 years old, these young activists have one powerful message to share: "each can act and impact its environment".
