We had an interesting thread some way back about the using over and over again of plastic water bottles. We have a habit of buying a pack of bottle waters every few weeks or so, and then refilling with tap water as and when necessary.
The interaction of the packaging with the food or water it contains definitely requires constant vigilance.
"The dangers of plastic containers to humans are magnified once they enter the environment. The same chemicals that can leach into human food, can leak into the soil, waterways and oceans when they are discarded, and according to the EPA "releases of BPA to the environment exceed 1 million pounds per year." According to the nonprofit Plastic Debris Rivers to Sea, up to 80 percent of ocean pollution is plastics. Plastics do not decompose into their constituent elements, rather they tend to break into smaller and smaller bits. The Algalita Marine Research Foundation tells the story of how, in the 1990s, researchers discovered a vast garbage patch of floating refuse in the Pacific Ocean. Additional garbage patches have been discovered since, where the weight of suspended plastic particles is six times greater than the weight of zooplankton, the base of the marine food chain. According to Algalita's video, "Synthetic Sea," a 2001 Japanese study has found that the small plastics in the ocean ingested by marine animals also tend to bind with toxins such as PCB, concentrating them up to one million times and thereby posing an even greater threat to marine animals."
The most corrupt FDA refuses to ban BPA and gives reassurances to it's safety.
Personally, I would not be reassured by any corrupt FDA assurances...
