This is called the “relative privation fallacy” - where it’s stated or implied that action shouldn’t be taken on one issue because larger issues also exist. It’s like suggesting that the police shouldn’t try to catch pickpockets because unsolved murders exist.

The truth is that it’s possible for organisations to work on multiple fronts at once and that making rules around food labelling doesn’t imply that “the world is[…] burning” isn’t also something that’s being worked on.
