Stolen Future Chapter 13 and 14

                              Quote Master 

1.) "Declining sperm counts loom ominously over this discussion, for these reports harbor implications that 
extend beyond the question of male fertility."

This quote is extremely important because it introduces the problem and foreshadows the possible results that it might have which is much of what the chapter is about. In fact, this problem seems to extent beyond control and is not applied to male fertility.  

2.) "Animal experiments indicate that contamination levels sufficient to impair sperm production may affect brain development and behavior as well."

This quote's significance lies in the fact that the contamination levels have a great impact of human health.  It not only impairs sperm production but it also affects brain development and human behavior as well.

3.) "What is at stake is not simply a matter of some individual destinies or impacts on the most sensitive among us but a widespread erosion of human potential over the past half century."

This quote shows that the disease not only affects individuals but it greatly impacts the nation as a whole.  If detrimental, it can have a negative impact and harmful results on the entire human race.  This quote also states the the time over which the disease might affect humans for. 

4.) "Falling sperm counts could be an unfortunate historical episode- an unforeseen consequence of the midcentury experiment with persistent chemicals, which many countries have now wisely discontinued."

This quote is the most important one of all.  It states that the problems and disease was an unforeseen event that have devastating results.  However, because countries have discontinued these chemicals, the continuation of the problem is also stopped. 

5.) "It would be comforting to know that hormonally active chemicals are not casting a shadow on the next generation, but the evidence provides no such assurance."

This quote's significance lies in the fact that the hormonally active chemicals are indeed casting a shadow on the next generation.  The fact that the chemicals are having an impact of the next generation is potentially dangerous because it shows that the chemical is inheritable and is able to affect many generations onward.
