What Is Nature Worth?

[Ringing of cash register; tremolo call of a loon]

What is nature worth? Can its value be quantified? Some ecological economists and policy-makers say it’s important to have a common language of value when making decisions about land use and environmental management.

Dr. Robert Costanza of Portland State University says that nature provides us with many services that we can value – services for which we would otherwise have to pay dearly. Wetlands, for example, help protect us from hurricanes and floods and purify surface waters.

Dr. Costanza and his colleagues calculated the value of the ecosystem services of the State of New Jersey. They determined that freshwater wetlands in the state rendered services worth about $11,000 per acre per year, and the state’s beaches provide services worth about $42,000 per acre per year. [Wave hits a beach] They calculated the total value of New Jersey’s ecosystem services at approximately $18 billion a year, about as economically valuable as the state’s construction industry.

Studies like these help us understand the economic consequences of altering natural habitats.

[Better recognizing and quantifying how nature contributes to our sustainable well-being can only help us appreciate and value it more.]
