There have been unending questions of the reasons behind a decline in male population over the years. This piece of the essay will be concerned with writing a movie reaction of a movie titled “The Disappearing Male ~ Biphenyl A (BPA) ~ Where Have All The Boys Gone?” obtained from Vimeo Channel. The movie has several claims that environment plays a major role in sexual preferences between male and female. This movie reaction writing is intended for debunking lies or myths that are affiliated to the speakers of the movie that was intended to educate the public on what is hidden behind the notorious declining male figure in the society. The reaction will indicate how the claims raised in the movie are skewed and depends merely on the myths or lies rather than carrying out an inquire of the existing recent pieces of research done on the same in order to compare the results with myths that are propagated in the movie. An analysis of this move will help in identification of the gaps in knowledge that can be picked from the movie. These gaps can be used by the directors of the movie to reproduce another movie which is directed to reducing the many unsupported claims from the movie. In addition to that the movie reaction will help the public in the debunking un-evidence based claims.
It is not until one watches the clip at the 5th minute when the person comes across a claim that the there is lower male to female birth ratio. The speaker of the movie attributes this to the growing number of synthetic chemicals such as biphenyl A but this claim is not based on real facts as they have emerged on the recent studies. Contrary to that claim of fewer boys at birth, according to Warede, Balsarkar, and Bandekar (2014), the number of boys outnumber the number of girls at birth. The findings established that the case is through all over the world and is not sensitive to any geographical location. The findings indicated that there are around 105 or 106 boys for every 100 girls. From these findings, it can be realized that the claim of more boys than girls at birth is skewed and made in a persuasive manner. The use of rhetoric is playing a major role in making a claim that is unfounded if these statistics are anything to go by and base our arguments. To propel the rhetoric, the movie shows a clip from a hospital setting to project the realities to the public but as discussed in the figures above, the birth ratio is in favor of boys.
In addition to the first claim that the birth ration of females is higher than boy which has been proven unfounded, there is a second claim that the placenta offers no protection for a male child. This claim is found at the 14th minute in the movie. The movie continues to claim that due to this failure of the placenta to offer protection, the declining number of males is as a result of the poor protective nature of the placenta and this has led to the males suffering from the exposure to hazardous chemicals which destroys them before birth hence decreasing the number of boys being born at birth. However, available pieces of research prove the claim otherwise. According to Sarah and Jeremy (2015), among the key findings that were noted as the effective functions of the placenta was the protection that the placenta offers to the chemicals, drugs, and antibodies that could have otherwise been dangerous to the fetus. The findings indicated that some drugs are able to bypass the placental barrier but it found out that quite a number of drugs have been effectively prevented from reaching the placenta and this has been of great benefit to the baby. In addition to that, the study found out that the placenta was effective in the prevention of anti-D antibodies that could have otherwise resulted in fetalis. This protective nature has been beneficial to both boy and girl child hence the claim above is unfounded and cannot be used as the point of reference in making government policies and other health related regulations that will go a long way in changing the lives of many.
The movie continues to make other claims that the reason behind the declining number of male child is due to phenyl A found in plastic materials found in plastic containers and other plastic materials. This claim is at the 30th minute. The movie claims that the presence of phenyl A result of increased cases of testicular cancers. In fact, it claims that phenyl A is teratogenic hence causing cancer to patients not only male but also in female patients. The speaker in the movie argues that even most of the tubes used for emergency services such as nasogastric feeding tubes contain, endotracheal tubes among others contain these chemicals which are dangerous to our the vulnerable male child. The movie claims that this causes increased cases of male fertilities. The speakers claimed further that the phthalates and phenyl A is associated with birth abnormalities and those abnormalities have even more intense on the vulnerable boy child. The movie also uses the rhetoric to state that over 7 billion pounds of phenyl A are produced yearly despite its dangerous effects on human beings and for that matter a male child.
One of the questions that the speakers on phthalates and phenyl A should have asked themselves is: what does the available literature say about this phenyl A product? A research was done on the phthalates and phenyl A revealed results that were contrary to what has been said by the speakers. According to Short, Yang, and Jenkins (2013), there is no association of phenol to birth defects. This, therefore, rules out the effect of phenols on the cause of maternal birth defects to babies. All p values were found to be >0.24. This clearly shows that was no relationship. The phthalates were also tested in the same research and the results indicated that although the relationship of heterogenicity, unlike the claim that there is a massive effect of phthalates on birth defects, the research only found some association and the word “some” association as used in the text indicates that the association is not such strong to cause such a big alarm for such a big difference between boys and girls (Sarah, and Jeremy, 2015). The same research also did an investigation on the effect of phenyl A and the results found and an inverse proportion which was a U-shaped when plotted on a graph. Therefore, in this case, the result being an inverse indicates that the in fact at certain levels the phenyl A was beneficial to babies unlike what is claimed in the movie. Mothers exposed to phenyl A gave birth to babies whose head circumference was larger than those babies whose mothers were not exposed to phenyl A.
The movie has also the fourth claim. The movie claims that the reason behind the declining male to the female birth ratio in favor of females is the presence of many miscarriages which affect boys and this leads to a decline in males on earth both in animals and human being but one question that we should ask ourselves is whether this claim is true. This claim is made at the 21st minute of the movie. The movie even goes ahead to associate the phenyl A with the increased numbers of boy miscarriages due to the presence of phenyl A. However, this claim is cannot be plausible. Contrary to that there are more boy miscarriages than girl child miscarriages, the claim is not true as more boys child are born at the time of giving childbirth(Warede, Balsarkar and Bandekar 2014). According to Warede, Balsarkar, and Bandekar (2014), the number of boys outnumber the number of girls at birth. The findings established that the case is through all over the world and is not sensitive to any geographical location. The findings indicated that there are around 105 or 106 boys for every 100 girls. From these findings, it can be realized that the claim of more boys than girls at birth is skewed and made in a persuasive manner. The use of rhetoric is playing a major role in making a claim that is unfounded if these statistics are anything to go by and base our arguments. To propel the rhetoric, the movie shows a clip from a hospital setting to project the realities to the public but as discussed in the figures above, the birth ratio is in favor of boys.
The fifth claim is that the cause of less number of boys is as a result as a result of evolution rather than the presence of hazardous chemicals. This claim is made towards the end of the movie at 42nd minute. The speaker claims that chemicals are not the cause since even human beings are made up of chemicals. However, this claim is not true. There might be evolutionary causes but the claim that chemicals cannot be the cause of a mismatch in sex is unfounded. According to Short, Yang, and Jenkins (2013), hazardous chemicals have an influence on sex and male sex being a weaker sex is more affected. There are many chemicals that have been associated with birth defects and considering the environmental effects, some chemicals impacts on the health of a pregnant mother hence cannot be ignored. By the speaker saying that the human beings are made up of chemicals hence cannot hence chemicals cannot be the source of the problem; the speaker forgets that some chemicals are dangerous to live while others do not pose any danger. Therefore the argument here is that chemicals that a human being is made of are not harmful to the body unlike chemicals obtained from outside. In addition to that, human beings are also made of biodegradable chemicals also referred to as organic chemicals while some of the chemicals obtained from external environment are inorganic chemicals which make a comparison a challenge.
Based on the above analysis, there are five major claims on movie. The first claim is that the birth ratio favors girls when compared to boys. This claim has been proven to be untrue as more boys are born than girls. The second claim is that the placenta offers no protection to the fetus at all. This claim has also been proven unfounded as the placenta plays a major role in the protection of the baby against many chemicals including drugs. The third claim is that phenyl A causes birth defect and the last claim is that the sex differences is as a result of evolution.
