Something very similar is occurring with environmental costs. There are countries in Europe, the United States, Canada and other developed countries that have established stringent environmental regulations in the last thirty years, mainly as result of the action of "green" movements and a new environmental culture giving priority emphasis to "conservation", even above "production". In many of these States forestry, for example, is strictly controlled and the environmental costs to enterprises are very high, since they must replace the trees they cut down, are prohibited from felling certain species, etc. Delocation of these activities to countries without much environmental control has proceeded persistently in recent years, with drastic environmental consequences in the countries at the periphery. Mass deforestation in the Amazon jungle, eastern Asia and many other parts of the world originates in this practice.
