The second is eco-feminism. It combines modern radical feminist beliefs with those of environmentalism. The eco-feminist believes that a male dominated society will inevitably pollute its environment, while a matriarchy would handle our natural resources more responsibly. A third is bio-centrism, or deep ecology. Bio-centrism puts the worth of the biosphere above that of humans.
Humans are still worthwhile, but as a part of the larger biosphere.
Environmentalism uses aspects of Marxism, and it is often associated with liberalism. Environmentalism, however, is different from these two ideologies at their roots. There are a number of general philosophical differences between Greens and Socialists that revolve around their similarities with each other and differences from Liberalism. Socialism and Environmentalism rest on the presupposition that subjects or selves are not isolated discrete entities in a mechanical universe, but are instead part of a larger whole. The difference between Greens and Socialists is to be found in the ontological whole which they give a priori status to, i.e. the whole which they hold sacred and see as the source of their human potential.
