Jane Shaw discusses the possibility for individuals to protect the environment through free markets. She briefly explains why the world is suffering of many environmental problems and details on the importance of understanding economics to diagnose and solve them. She also comments on the tragedy of the commons concept, created by Garrett Hardin in 1968 – a tragedy that according to its author can be solved through private property and managed commons. Shaw describes the sources for creating the concept of free market environmentalism that include Neoclassical and Austrian economics; she also shares the examples of free markets that are working for the environment such as the water trade to keep fish alive and the protection of African elephants – a species that has suffered the illegal ivory trade.
