Morning of the no bells for winter
Consumption can be art. Waste, a separate idea, can also be art.
Consumption art must take account exactly of what is consumed and catalogue how exactly it is consumed, unless it is a nihilistic, DADA-ish form of consumption art, or specifically anti-product, or something like that.
An example of consumption art would be eating cherries as you watch the jumper drown.
Charity can also be art, so long as it’s unneeded.
Cruelty can also be art, so long as there’s no personal motivation.
Waste art must take account exactly of what is thrown away, though only very ambitious waste art will attempt to catalogue what happens to what is thrown away over time. Even eco waste art cannot compensate for specialty audiences, like electron microscopes or post-apocalypse survivalists, though any performance of waste art includes a permanent installation.
This is different from, say, consumption art, which crafts only the intake of the original product.
An example of waste art would be writing FORGERY on a physical piece of art.
Another example of waste art would be talking.
