What are important environmental benefits ecosystems provide, such as clean air to breathe, clean water to drink, and fertile soil in which to grow crops?

Ecosystem services are the benefits people receive from the natural environment, such as clean air, clean water, and fertile soil for crops. These benefits come from how ecosystems function—plants and soils regulate the atmosphere and filter pollutants to improve air quality, wetlands and soils purify and hold water, and ongoing nutrient cycling builds fertile soil for plant growth. This term directly names the advantages to humans that arise from ecosystems, not just the components themselves. Other terms describe resources or parts of the system rather than the benefits they provide: natural resources are harvestable materials, biodiversity is the variety of living things, and agricultural resources refer to crops and farming inputs. So, ecosystem services best captures the idea of the environmental benefits described.
