The world of design is facing a reckoning. As climate change accelerates and resources dwindle, some materials are vanishing… and in some cases, that’s not a bad thing. The decline of certain substances signals a shift away from unsustainable practices towards more responsible alternatives.
The Vanishing Traditionals
Some disappearing materials represent a loss of cultural heritage. Kapa barkcloth, crafted from Hawaiian wauke trees, is an example. Both the trees themselves and the traditional knowledge surrounding their use are fading. Similarly, the Plicopurpura pansa sea snail of Mexico’s Pacific Coast—historically used for its vibrant violet dye by Indigenous communities—is also in decline. These losses highlight how environmental pressures impact not just ecosystems, but also deeply-rooted cultural practices. This matters because it underscores the interconnectedness between environmental health and human traditions.
The Purge of “Forever Chemicals”
However, not all material declines are tragic. In August, Illinois passed a law banning PFAS (per- and polyfluoroalkyl substances) from products by 2032, with other states following suit. PFAS, developed in the early 20th century, were initially hailed as a breakthrough: they made cookware non-stick, pizza boxes grease-resistant, and clothing waterproof.
The problem? PFAS are “forever chemicals.” They don’t break down in the environment and accumulate in both ecosystems and human bodies, posing significant health risks. The crackdown on PFAS represents a crucial step towards phasing out persistent pollutants—a victory for public health and environmental protection.
The disappearance of PFAS is a deliberate choice, not an inevitable loss. It’s a sign that we’re finally recognizing the true cost of certain materials and prioritizing long-term sustainability over short-term convenience.
The shifting landscape of design materials is forcing a reckoning with what we choose to keep and what we let go. Some losses are mournful reminders of cultural erosion, while others are necessary steps towards a healthier, more sustainable future.
