Ecoradicals think that the ecosystem has a limited carrying capacity. Such a limit ‘defines how large a species population can become before it overuses the resources available in the ecosystem’. They believe that human societies on earth are moving dangerously closer to the limits of the planet’s carrying capacity; they also think that there are no simple technological fixes that can take care of the problem. Therefore, many ‘ecoradicals’ call for strict population control and dramatic change in modern lifestyles towards a more environment-friendly, less consumption-oriented and waste-producing way of life (Introduction to International Relations: Theories and Approaches by Robert H. Jackson, Georg Sorensen, p. 257).
