[[Image:Uses12.jpg|thumb|left]]A [[non-use value]] is a value associated that does not concern our use, wither direct or indirect, of the environment, its resources or services. The value associated with the concern that future generations should have access to theses resources and opportunities to make use of them is bequest value. Beyond this, there may be existence values that are not associated with any human use or option of human use of these resource, but which reflect simply the value of knowing that the environment or resource exists in a healthy state. For example, may people donate money to conserve dolphins and even though they may never see a dolphin, knowing that they exist is beneficial to their quality of life.

Bequest value and existence value

Uses12.jpg
A non-use value is a value associated that does not concern our use, weither direct or indirect, of the environment, its resources or services.

Bequest value: The current generation places value on ensuring the availability of biodiversity and ecosystem functioning to future generations. This is determined by a person’s concern that future generations should have access to resources and opportunities. It indicates a perception of benefit from the knowledge that resources and opportunities are being passed to descendants[1].

Existence value: This is the benefit, often reflected as a sense of well being, of simply knowing marine biodiversity exists, even if it is never utilised or experienced, people simply derive benefit from the knowledge of its existence (Hageman, 1985[2]; Loomis and White, 1996[3]). The considerable importance which the wider public attach to maintaining diverse marine life is revealed through their interest in marine based media presentations, such as the ‘‘Blue Planet’’. In addition, articles on cold water corals frequently appear in the media (http://news.bbc.co.uk/1/hi/ sci/tech/3719590.stm,2004), despite the fact the majority of the general public will never see a cold water coral, they are interested in them and benefit from their existence.
