Nonfiction Reading Response #2


           According to the article, United Nations Panel Calls Hormone Disruptors a “Global Threat” by Brian Bienkowski and Environmental Health News, hormone linking chemicals are the main threat to the health of humans and animals. These chemicals are the organic pollutant chemicals such as, DDT and polychlorinated biphenyls, and ubiquitous chemicals such as biphenol A and phthalates. This had been growing increasing over the last decade. These chemicals are referred to as a global threat, for that it had been spread across the continent. Many people look upon this chemical as a living threat to humans and that it had to be eliminated, however, others thought it isn’t a bad thing.

            Chemicals like DDT and polychlorinated biphenyls are a major threat to humans and animals, “[They] are now banned in the U.S---traveled the globe, persisted in the environment and caused severe population declines in some wildlife species” (Bienkowski 1). These chemicals are very quick at spreading and contaminating the environment which resulted in the decrease of wildlife. Humans are not killed from this chemical, instead, their health is directly affected.

Such diseases include male reproductive problems, pregnancy complications…obesity and brain development. Many factors can cause such diseases, but the report concludes that given how fast some of these are rising, environmental chemicals are likely playing a role (Bienkowski 1).

            Even though these diseases can’t be comparable to cancer and other untreatable sickness, but they can be quit complicated. For example, pregnancy complications can directly lead to the development and growth of their offspring. It may also lead to stillborn and other severe problems. Obesity and brain development can lead to a person’s ability to remember, and to learn. Reproductive problems can interfere with a person’s ability to reproduce.

            DDT and polychlorinated biphenyls are still a threat to us, but other chemicals such as the bisphenol A and phthalates are found in everyday products (Bienkowski 1). These chemicals can come in direct contact with us and cause health problems. These chemicals are known as pseudo persistent because they don’t stay in the environment for long, but we expose to them all the time so it’s would have the same effect as if it was persistent.

            There had been more than enough evidence to prove that these chemicals are harmful and that it should be banned. But on the other hand, the government agencies and industry groups are not so convinced of this. In responding to the threat of DDT and polychlorinated biphenyls to wildlife, they say that, “…particularly killer whales and harbour seals. Both have high levels of PCBs and flame retardants that accumulate in ocean ecosystems” (Bienkowski 2). This means that this chemical only kill whales and seals and not all the animals. In responding to human threat, they made a point that, “…very low levels of human exposure to BPA through the diet are unsafe” (Bienkowski 2). There isn’t enough people who are being expose to these chemicals that are having health issues and they stated that the chemicals in the food does not have a major effect on humans. “Unless we know where the chemicals are used, and they’re tested, it’s tough to make informed decisions on how to protect people” Woodruff said. Many of these chemicals had not been tested, so scientists cannot decide whether or not it is absolutely harmful to us.

            Overall, I think that even though these chemicals had not been directly proved to be harmful, they should still be banned due to the health complications that it might cause. I think that if these chemicals are ban then there wouldn’t have been so many arguments on if it’s good or bad.
