When we consider the plastic packages we use every day, we might think about the harm to the environment. But few of us wonder whether or not these packages might actually be bad for our health. In fact, scientists in the UK believe that “plastic pollution could be about to get personal” for British teenagers.

86% the teenagers..
BPA, explained Science Daily, is widely added to plastic packages to make them strong. The chemical can be found in plastic bags and water bottles. DVDs, CDs and sunglasses also have BPA.
To understand the possible dangers of BPA, we have to understand the human endocrine( 内分
泌的) system. The endocrine system produces something special which affects our growth slowly. Once inside the body, BPA influences the human endocrine system and may affect some body functions.
The US Food and Drug Administration has banned the use of BPA in the making of baby bottles in order to stop BPA going into baby bodies. And some worry BPA may cause diabetes(糖尿 病) and heart conditions, but they are not sure. So, if you really want to continue using plastic bottles,
you can do that, but don’t forget to recycle them.
