Clearly the conditions in such a definition exclude quite a lot of tourism that derives at least some of its value from biodiversity. In 1992, 7% of American travellers stated that they had taken at least one ecotourism holiday and 30% (35 million people) declared that they intended to take one in the next three years (US Travel Data Center 1992).

A new awareness will need to be based on a new ethic that gives greater value to the natural environment and to the fair sharing of its costs and benefits. But it will also need to be based on the application of political and economic argument at all levels of society where environmental decisions are made.

There would be facts, too, on the Why conserve bird biodiversity? 21 benefits. How many jobs created, how much profit earned? Even if all the facts are known and agreed, the decision as to whether to proceed with the mine is not simple. Different people will weigh the facts with differing ethical perspectives and reach different conclusions. A utilitarian viewpoint values the natural world purely from the perspective of its instrumental utility to humans. Others believe that natural things have an intrinsic value in their own right.
