    This is quite a read but it's scarily uneasing. Could it have implications to our birds, i would say yes wothout doubt.

    The subject matter is Bisphenol A which is made into plastic bottles, headlights, polycarbonate, plastic water bottles the type we feed birds with and so on. This is a short quote from the full article.

    First synthesized in 1891, bisphenol A came into use as a synthetic estrogen in the 1930s. Later, chemists discovered that, combined with phosgene (used during World War I as a toxic gas) and other compounds, BPA yielded the clear, polycarbonate plastic of shatter-resistant headlights, eyeglass lenses, DVDs and baby bottles.

    But during the manufacturing process, not all BPA gets locked into chemical bonds, explains Tim A. Osswald, an expert in polymer engineering at the University of Wisconsin–Madison. That residual BPA can work itself free, especially when the plastic is heated, whether it’s a Nalgene bottle in the dishwasher, a food container in the microwave, or a test tube being sterilized in an autoclave.

    The net result of this chemical leaching out range from birth defects, cancer and behavioral problems to name a few.

    It's also well known that plastics like this are everywhere in the Oceans, they break down into tiny particles in sunlight and abrasion in the Oceans. In a recent study 1 sqr kilometer was netted and around a ton of plastic particles where brought on board, that was in the middle of the Pacific not close to a city. The same toxins are being released into the Ocean at the very bottom of our food chain, they do not disolve and are passed from one lifeform to the next. The righting is on the wall for the human race's long term survivability, it's just the fact we have not worked it out yet. What can we do, not very much really.
