Markets cannot incentivize conservation. They are designed to maximally use all available resources. In most cases it's a good thing, but in few cases it is catastrophic. (Think about it - the more is the resource being conserved, the more relatively abundant it becomes, and the cheaper it becomes in the market. The conservation of resource can only be done if it's use and extraction is punished, and free market only gives positive incentives.)
(That's why the markets cannot solve global warming for example, and that's why free market fundamentalists are often unable to believe that global warming is happening.)
