Planetary Health is an expanding scientific field around the world, and actions in different areas are essential to minimize the environmental damage that compromises the future of humanity. This project report aims to describe the development of Planetary Health actions in a rural school in the Brazilian Amazon, to understand and raise awareness of themes related to Planetary Health. To implement the educational activities, a booklet entitled “Planetary Health: Guide for Rural Education” was created. Subsequently, didactic sequences were applied to 37 ninth-grade students in the first semester of 2023. The activities were diversified, including: (1) investigative activities (pre-tests, interviews with family members, ecological footprint adapted to the Amazonian riverside context), (2) interpretative activities (image reading, identification and problem-solving for Planetary Health stories in the Amazon, educational cartoons, and graphs of the sectors with the highest pollution in Brazil and diseases associated with climate change), (3) audiovisual activities (educational videos), (4) playful activities (educational games), (5) practical and field activities (forest tracking, planting seedlings, sanitation trail, construction of a school garden, preparation of a healthy school snack, greenhouse effect simulation, and basic analysis of lake water with a probe). The results of the educational actions allowed students to undergo new experiences on Planetary Health themes, as well as understand the centrality of the Amazon for the planet and how the environmental impacts in this biome are compromising the future of humanity. The experiences during the educational actions showed that young riverside residents are concerned about the future of the Amazon, especially given the environmental destruction that is frequently evident, such as deforestation, fires, illegal mining, and land grabbing. Inserting these themes into riverside education makes it possible to look at the Amazon in a resilient, responsible way and to discuss scientific and local knowledge so that students can develop initiatives to face environmental challenges in their community. We conclude that Planetary Health education needs to be an effective part of the school curriculum, prioritizing reviewing the documents that guide education to prioritize transdisciplinary actions with children and young people, as they are the voices of the future and future leaders in emerging causes. Educational actions in Planetary Health in the Amazon region are an example that can inspire actions in other places with similar characteristics.
