Another common type of plastic bottle is made with bisphenol A, also known as BPA. These products are typically rigid plastic bottles intended for multiple re-use, such as baby bottles or water bottles carried by cyclists. Concerns about tests that may link BPA ingestion with cancer and reproductive damage in some animals and the possibility that BPA could leach out of plastic bottles and into the liquids they contain has led to bans on the use of BPA in plastic products intended for children (such as baby bottles), and has prompted some consumers to seek out non-BPA alternatives.
The question remains as to why exactly human subjects returned plastic to the sea. At that time the material did not degrade and remained permanently in the ocean, creating a toxic floating landmass. Born of the petroleum that was formed from the plankton that emerged in the Earth’s primordial sea, the return of plastic polymers to the ocean was nothing other than an aberration. This ‘return’ to the ocean was ultimately an act against the idea of a lifecycle, as there was nothing to digest or transform it into something organic. It was as if simply removing it out of the sight of culture, and into the realms of the unknown, was enough. It was only after this point that the lifecycle of manufactured objects became a design issue. The Spime was conceptualised at the beginning of the twenty-first century by the renowned science-fiction writer and design theorist Bruce Sterling. It comprised a progressive vision towards the kind of object that can be tracked throughout its whole life and through space and time.  Objects could be traced from the point of their first virtual representation, to their manufacture, their subsequent ownership history, their physical location, right through to their eventual obsolescence and decomposition to raw material, ready to be used for making a new object. Objects were created to be recorded and archived in real time, thus being traceable at any given moment. ‘Things’ were never the same again.
