In an era of geopolitical tension, climate misinformation, and increasing pressure on our planet’s natural systems, young people need the tools to make sense of complex environmental issues. Earth Day, first celebrated on April 22, 1970, recognizes the achievements of the environmental movement and promotes the protection of Earth’s natural resources.
Each year, Earth Day highlights a global theme—often focusing on areas such as renewable energy, biodiversity, or environmental justice. This year’s theme is Our Power, Our Planet.
The Economist Educational Foundation offers ready-to-teach lessons about Earth Day. The lessons cover the biggest topical issues of our time to help students learn, think critically, and talk about the issues affecting their lives. These “Topical Talks” are produced by experienced teachers, with guidance and support from The Economist journalists and fact checkers.
Each lesson contains clear teacher instructions; an accessible, student-friendly PowerPoint with presentation guidance; printable, interactive classroom activities, and key terms with definitions to break down new or challenging vocabulary.
Recent Earth Day lesson bundles include “Future Foods: What will be on our plates?” (exploring innovative methods of food production); “Air Pollution: Who is responsible?” (exploring the link between winter weather, air pollution, and human health); and “AI and Sustainability: Difficult choices?” (exploring the environmental impact of artificial intelligence: does the potential for innovation outweigh the environmental cost?). The lessons are appropriate for students aged 10–16.
Posters are important tools in helping people understand Earth Day. Even today, strong images can share a message more effectively than long explanations. A well-designed Earth Day poster can show care for the planet, a sense of urgency, and hope in just one glance.
The posters for Earth Day 2026 convey the theme Our Power, Our Planet. They invite people to pause, think, and act. The Earth Reminder website provides poster images for Earth Day 2026. The images are free to download and use to share awareness in your classroom, school, and community.
