Each year, Earth Day centers around a specific theme to address pressing environmental issues, such as climate change, plastic pollution, and conservation efforts. For example, the 2024 theme is Planet vs Plastics. The theme aims to bring attention to the serious issue of plastic pollution and how it harms nature. "Can we start reusing the same shopping bag every time we go shopping? Is it possible to use natural and organic materials, such as paper envelopes, glass or ceramic jars, or bamboo plates?" The 2025 theme is on renewable energy.
