Sustain NatureBridge
Like so many others, we have made difficult decisions in response to COVID-19 with far-reaching implications for our students, staff and future. Our programs—the reason we exist—are cancelled for the rest of the school year. That's 13,000 kids who don't get to experience their national parks this spring. For our nonprofit, it also means $5 million in lost revenue and significant staff reductions. We, like so many others, are in crisis.
