If You Love Nature, Desocialize It, por Manuel Lora, no Mises Institute.
«We are living under partial nature socialism. The government has arrogated to itself the responsibility to take care of some areas of land that it has declared important. By simply saying that it is so (through the issuance of law), groups of politicians claim to be the rightful owners of either previously unowned land or of land that already has an owner. Let's look at each one of these scenarios. (...) National parks are socialist parks. The same economic analysis used to determine the consequences of socialism can be applied to national parks, namely, that without a market there is simply no way to determine if the resources dedicated to the park system are being allocated efficiently. As Mises showed, economic calculation is impossible under socialism.»
