Contrasting the conservationist bias of environmental balance with that of sustainable development, the author distinguishes the influence of both in the current formulation of environmental policies, including trends, respectively, more regulatory or redistributive as public policies. In this sense, it highlights the global need to overcome natural conservationism, a remnant of the 19th century and whose obsession with the untouchability of nature does not admit the synergies between nature and humanity, fundamental to promoting sustainability. Which, if assumed as a progressive ideology, it transcends the left-right differentiation, implying broad coalitions, both political and socioeconomic, so that we become socially ecological.
