World Rainforest Day is not just a calendar event—it"s a call to action. Established in 2017 by Rainforest Partnership—a nonprofit environmental organization—the day raises awareness about the importance of rainforests and mobilizes efforts to protect them. In the US, the occasion is marked with community tree plantings, school projects, and social media campaigns that highlight conservation successes. Many botanical gardens host special exhibits, while environmental groups run fundraising challenges to support on-the-ground protection efforts.
