International Mountain Day is being celebrated with a triple approach focusing on innovation, adaptation, and youth. In Greece, students from Tsaritsani embark on a nature trail led by journalist Evangelos Mitroulias. They discuss the beauty and biodiversity of Mount Olympus, including the rare cacti found at its foothills. Environmental educator Andreas Ganasios emphasizes the importance of nature for urban children, while Dimitris Gounaras urges the protection of mountains as vital to life. The initiative has seen 50,000 children participate in educational hikes over the past 15 years, underscoring the mountains’ role in global biodiversity.
