I am writing about the affect on the economy, environment, and the health aspect.
Well there's plenty to talk about the environmentwhen you think of how many plastic bottles are used each yearyou could take about recycling patterns, effectiveness of recycling bottles, how manufacturers have made more efficient bottles, etc. As far as health something I find intriguing is the topic of harmful chemicals that come into the water you drink from the bottling plastic. A lot of it is based on limited research though, so it might not be the best topic. A more practical health aspect to talk about would be the minerals or lack thereof in bottled v. tap water.
Does the disposable bottle plastic contain BPA (Bisphenol A)? Medical researchers have raised ominous concerns over this chemical in recent years. Canada and the EU have outlawed this material for use in baby bottles only as recently as 2010. Canada has gone even further by declaring BPA toxic to humans. The US has yet to regulate this chemical in any meaningful way. Your typical disposable water bottle maker doesn't disclose the materials the bottle is made out of on the product label. They don't have to because there's no law that compels them to. BPA has been used in polycarbonate and thermoplastics since the late 1950s. In older buildings an epoxy form of it has been used to coat the inside of water pipes. It is also used to coat the inside of canned foods in your supermarket. Free-form BPA can be found on carbonless copy paper, on store receipts, movie tickets, to name a few. A government study in 2008 estimated detectable levels of BPA in urine samples in over 90% of the U.S. population. BPA mimics the human estrogen hormone inside the human body. Recent studies include concerns over a long list of specific health ailments. The list of health concerns include: Obesity Heart Disease Neurological Disorders Hyperactivity Attention Deficit Disorder Propensity for Drug Abuse Thyroid Disorders Breast, Brain, and Prostate Cancers Reproductive Disorders See source links below for more reference material and news articles.
