Diversity, whether bio or cultural, is key to sustainability. Monoculture is destructive of sustainability.
These photos were taken in my garden and its quite a wildlife haven (in the middle of a town). It runs on home-made compost, self seeded plants, and absolutely no pesticides or other poisons.
Yes, the 'lawn' has buttercups and daisies and other plants in it, but I prefer that to a pristine over-managed garden which depends on hours of labour or regular dousing with chemicals.
I use the garden as a metaphor for politics. Green political theory values cultural diversity because it's enriching, progressive and self-organising. Different perspectives inform each other which promotes healthy social progress. The opposite, where cultures are kept apart, leads to prejudice, isolation and antipathy, a blinkered view of the world, and, ultimately, war. What could be more destructive?
