Nomenclature

This could just be a projection because of my own thoughts and views on the world. Anyshoo.. I think Bird is talking about a disdain he has for modern society and the decadence and destruction thats synonymous with it.

The first line is considering all the other alternatives there are. Instead of selling the coats like we do in our consumerist world, we could be making our own (this encompassing all the other things we could do ourselves also and referring to other cultures who still do or a time when we did, while living more harmoniously with nature) and yet we don't because its not 'the easy way' Its much easier now for us to 'pay to play' as it were.

Then he is telling us its time we collectively asked for this to be changed. He cleverly referenced See'n'say here, asking them to bring us an alternative vernacular to what we have and know. Our scientific taxonomy is not the only naming system there is. Other groups of peoples have their own taxonomy, which again I believe he's referring to other cultures and how their ways of living are in a lot of respects superior to our superfluous occident ones. Appealing for a different nomenclature is appealing for a different way of viewing and interacting with the world.

Colours bleeding to grey to 'ones that don't exist in nature' i took to mean our monotonous man-made colours that we've painted over nature with.

'A Nomenclature is washing away' is referring to the 'things' that we've given whole naming systems to, slowly becoming extinct ironically because of us which thus renders our catalogues redundant and our efforts worthless.'its washing us all away' then could loosely be talking about global warming effects and our impending doom! ...perhaps?
