 Important contemporary currents are anarcho-primitivism and social ecology.Notable contemporary writers espousing green anarchism include Murray Bookchin, Daniel Chodorkoff, anthropologist Brian Morris and people around Institute for Social Ecology; and those critical of technology such as Layla AbdelRahim, Derrick Jensen, George Draffan and John Zerzan; and others such as Alan Carter.Social ecologists often criticize the main currents of socialism for their focus and debates about politics and economics instead of a focus on eco-system (human and environmental).
