Nature supports people in critical ways, often at a highly local level. Wild bees buzz through farms, pollinating vegetables as they go. Nearby, wetlands might remove chemicals from the farm’s runoff, protecting a community drinking water source. In communities all around the world, nature’s contributions are constantly flowing to people. Scientists have mapped these contributions at local levels for years, but a new Stanford-led study puts these local analyses on an interactive global map that emphasizes nature’s declining ability to protect people from water pollution, coastal storms and under-pollinated crops.
