Pernicious Plastics and the Precautionary Principle

History has shown that several plastics, originally considered completely benign, have since proven harmful to ecosystems, animals and ultimately to human health, demanding their control and in some cases elimination from use. This essay discusses the effects of PVC on human health (including a brief look at dioxins and phthalates) and the unsustainable PVC 'deathline'. It stresses the need for, and debates the practicality of, adopting the precautionary principle to limit the adverse effects of plastics.
