Non-use value: bequest value and existence value

Bequest value and existence value

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.
