Ocean acidification isn’t something that most folks lose sleep over. As a side effect of climate change, it doesn’t present a striking image the way a crack in the Antarctic ice shelf or a hurricane-battered coast might.
But some problems need to be seen to be believed, so David de Rothschild, founder of the lifestyle brand The Lost Explorer, and Lauren Bowker, the alchemist-cum-designer behind The Unseen, took it upon themselves to draw out the visually indiscernible.
They accomplished this feat by devising a special kind of T-shirt, one that changes colors in response to a water’s pH. No toxic chemicals were employed to create the effect: just cabbage. Lots of cabbage.
