Fruits, vegetables, trees, fish, and livestock are available to us as direct products of ecosystems. When people are asked to identify a service provided by nature, most think of food. The Millennium Ecosystem Assessment (MA), a major UN-sponsored effort to analyze the impact of human actions on ecosystems and human well-being, identified four major categories of ecosystem services: provisioning, regulating, cultural and supporting services.
The benefits can be direct or indirect-small or large. An ecosystem service is any positive benefit that wildlife or ecosystems provide to people. The value of nature to people has long been recognized, but in recent years, the concept of ecosystem services has been developed to describe these various benefits. We have a stronger economy, diverse food products, and advancements in medical research as a result of wildlife and natural ecosystems.
Wildlife is important to the heritage, culture, and heart of America, and we want to preserve it as a legacy for our children.Īlthough you cannot put a value on all the ways the natural world enriches our lives, there are many tangible benefits to living in a world with strong and healthy ecosystems.
