Cost I'm sure. Nitrogen is slightly lighter than air, carbon dioxide is heavier than air. They are lowered into the CO2 chamber. If it were nitrogen it would need to be redesigned.
Why are no startups exploring nitrogen? The world isn't going to go vegan. Cost effective nitrogen gas chambers could reduce a fair amount of animal suffering in a pragmatic way.

- Ancapistani 4y agoI'd say that pretty much everyone involved cares - either about the animal's experience, or about the financial impact. As I said elsewhere, at least in this case those incentives are largely aligned.
