Cities are growing—fast. By 2050, two-thirds of the world’s population will live in urban areas.
The actions we take over this next decade will define the planet's path over the next century. The Nature Conservancy is urgently taking on the dual threats of biodiversity loss and the climate crisis, maximizing resilience and benefits for communities. What we achieve is just as important as how. By letting science guide our focus and equity guide our execution, we can shape a better 2030 for our planet.

Urban Roots
A century ago, New York City embraced a powerful tool for improving urban life: planting trees. The city recently completed an effort to plant another million trees—this time to help tackle climate change.
