Encourages unhealthy drinking options

The argument

This argument holds that banning bottled water backfires on public health: removing the healthiest packaged drink from shelves encourages people to reach for unhealthy alternatives instead. A ban on bottled water does not eliminate the situations in which people buy a drink — thirst on the go, vending machines, shops, cafeterias. It simply removes the one option in the cooler with no sugar, no calories and no additives, while leaving soda, sweetened juices, energy drinks and other sugary beverages untouched. The predictable result is substitution: a person who would have bought water buys something less healthy instead. This is not speculation — research on a US university campus that removed bottled water found that consumption of sugary drinks rose after the ban, while the number of plastic bottles shipped was not meaningfully reduced, since the substitutes came in plastic bottles too. That outcome defeats the ban's purpose twice over. Public health is harmed, because sugary-drink consumption is linked to obesity, diabetes and tooth decay — harms far more certain than any benefit from removing water. And the environmental goal is not achieved either, because the bottles remain; only their contents change for the worse. A policy that makes the unhealthy choice easier than the healthy one is, on this view, perverse regardless of its intentions. From this standpoint, bottled water should remain available precisely because it is the benign option among packaged drinks, and removing it steers people toward worse ones. Because banning bottled water encourages unhealthy drinking options, this argument holds, water bottles should not be banned.

Premises

Counter-arguments

The argument equates removing bottled water with removing water, and the equation does not hold. Bans of this kind are ordinarily paired with the provision of drinking water by other means — refill stations, fountains, taps and reusable containers — so the healthy option remains available and free; what is removed is the packaging. Where that infrastructure is installed, the substitution effect the argument predicts has no reason to occur, because nobody faced with thirst is choosing between a soft drink and nothing. The evidence base is also thinner than the confident phrasing suggests. A single American university campus is one setting, with a captive population, particular vending contracts and a specific implementation; generalising from it to municipal or national policy is a considerable leap, and the finding that plastic shipments did not fall points to a poorly executed ban rather than to a necessary feature of banning. Supporters of a ban would add that in places with safe tap water — where most bottled water is in fact sold — the product substitutes for something already available at negligible cost and environmental impact. If the concern is genuinely that people will reach for sugary drinks, the measures aimed at that problem are the ones directed at sugary drinks: taxes, availability limits and labelling, none of which require keeping bottled water on the shelf.

Rejecting the premises

[Rejecting P1] A ban removes the packaging rather than the drink; where refill stations, fountains and taps are provided alongside it, water remains the freely available option. [Rejecting P2] A single campus study with a captive population and specific vending arrangements is a narrow basis for a general claim, and the failure to reduce plastic shipments indicates poor implementation rather than an inherent flaw in the policy.
