Consider the economic value of a resource that is essential but not scarce: gravity. On one hand, without gravity we would all drift out into space and die; indeed, life on Earth would never have arisen at all, planets would not exist to orbit a sun, and so on. Gravity is essential to life, and therefo to which residents object, it is tempting to assume that the emissions are an externality because the factory is imposing them upon the residents. However, that conclusion dependson, adaptation and evolution within systems of interacting organisms and non-organic resources. Without the dynamics of the systems in which they are found, re its value is infinite and incalculable. On the other hand, no one is in a position to remove or to eliminate gravity, and nobody is able to exclude others fr om its effects. It is not scarce. It is not a consumable resource but a constant physical property. No one has rights to gravity and no one has the right or ability to take it away. No one would pay for gravity since there is no way to avoid it, and there is no ability or reason to get more or less of it than one inevitably is exposed to. Therefore, the economic value of gravity, a feature of nature upon which life depends, is zero. However, if Joyce has a right not to be defamed and Bob's words have the effect of lowering Joyce's character in the estimation of her peers, then Bob's speech violates Joyce's right. The conclusion depends on the existence and definition of the rights held by each party. It is impossible to know which party imposes upon the other without contemplating the rights in issue. The same is true for air emissions. Where a factory produces air emissionsthe phenomena would not exist. Therefore, protecting ES requires that the systems in which they exist operate and evolve in the way that they do. Ecosystems are unplanned, dynamic, chang upon both the extent of the rights held by the residents and the nature of the emissions created by the factory. If the residents have no right to be free from air emissions, the factory is Since in an ecosystem everything is connected to everything else, to assign importance to a specific list of ecosystem features is problematic. All organic processes, whether directly useful to humans or not, are products of the ecosystem within which they occur – the result, but not the end resulof millions of years of competition, natural selectiing, uncertain, and uncontrolled. Those are the conditions that produced ES. Aiming to specifically protect ES to the exclusion of the rest of the system does not sustainsClick Here
