Much of what they do can be done without eliciting the ire of nation-states. Bike shares, pedestrian zones, insulated buildings, renovated port facilities, congestion fees, car emission limits, furnace specifications, fuel upgrades (from oil to gas to alternative energy) and white paint roofs, for example, are only some of the innovations city officials can promote to effect significant reductions in emissions and pollutants.

here states have grown dysfunctional and sovereignty has become an obstacle to global democratic action—as when the United States (or China, France, or Canada) refuses to compromise its sovereignty by permitting the international monitoring of carbon emissions on its soil—cities have increasingly proven themselves capable of deliberative democratic action on behalf of sustainability, as they have actually done in intercity associations like the C-40 or ICLEI. If presidents and prime ministers cannot summon the will to work for a sustainable planet, mayors can. If citizens of the province and nation think ideologically and divisively, neighbors and citizens of the towns and cities think publicly and cooperatively.

he um belt has two sides to it which are not separable in german they're the merkveld and the virgvelt the merkwelt is the umvelt considered 00:19:24 from the aspects of semiotics or signs or meaningful stimuli things to differentiations one might draw distinctions one might draw that are available to one the virgvelt is the same thing 00:19:37 considered under a different aspect which is the space of possible effective actions to draw a distinction is now to move in knowledge of that distinction 00:19:49 this notion of the virgvelt will will appear later in ecological psychology with the notion of affordance and and again a concept that follows totally nails long before it appears in the literature 00:20:02 so when you hear umwelt try not to think entirely visually but to recognize that we we're dealing here with a concept which must be understood as a sort of a stereoscopic fusion 00:20:14 of the idea of meaningful appearance meaningful showing up and capacity for action because of the difficulties in disciplining this view of this emerging 00:20:28 view of the subject you won't find it easy to interpret vulnerability in terms of personal experience he vacillates here and our vocabulary is still not great here but the umvelt has 00:20:40 this important character of being neither a theory of perception or theory of action in keeping with all embodied theories later perception and action are absolutely indistinguishable but we can characterize them in this 00:20:53 with this dual aspect manner so when you encounter sketches like this he's full of bold imaginative sketches in his work
