Ecosystem services l.jpg
Ecosystem services

Definition: refers to all the processes through which natural ecosystems and the species they contain help sustain human life on this planet.

Examples: Purification of air and water, mitigation of droughts and floods, generation and preservation of soils and soil fertility, detoxification and decomposition of wastes, pollination of crops and natural vegetation, dispersal of seeds
