 Many see the breakdown of traditional forms of community, wasteful consumerist lifestyles, the destruction of natural habitat, urban sprawl, factory farming, and over-reliance on fossil fuels as trends that must be changed to avert ecological disaster and create richer and more fulfilling ways of life.Ecovillages offer small-scale communities with minimal ecological impact or regenerative impacts as an alternative.However, such communities often cooperate with peer villages in networks of their own ("see" Global Ecovillage Network for an example).
