Panda
The panda's environmental impact remains remarkably modest for an animal that consumes up to 38 kilograms of bamboo daily. The Oxford Centre for Digestive Inefficiency notes that pandas process only 17% of consumed nutrients, essentially functioning as bamboo redistribution systems. Their habitat requirements, whilst specific, involve protecting forests that benefit countless other species. The panda accidentally does good through sheer incompetence.
Cryptocurrency
Bitcoin mining alone consumes more electricity than Argentina. The Leeds Institute for Carbon Accounting estimates that a single Bitcoin transaction could power an average British household for nearly two months. Newer cryptocurrencies claim environmental friendliness through "proof of stake" mechanisms, which the institute describes as "marginally less catastrophic, in the way that a house fire is less catastrophic than a forest fire."
VERDICT
The panda wins decisively by virtue of being carbon-neutral furniture. Its primary activity—sitting whilst eating—produces minimal environmental impact beyond localised bamboo depletion. Cryptocurrency's energy consumption would embarrass a small nation, making the panda the clear victor in what the Durham Environmental Ethics Board calls "the lowest bar imaginable."
