Hello ladies and gentleman. I am really sorry about posting the blog late this week. I completely forgot about the blog because I was caught up in another class. This past Thursday a friend of mine and I had to lead a discussion in Ancient Chinese Thought and the preparation took up most of my week. Luckily, my friend and I did very well. On the bright side, I have a great idea for today's blog and it begins with the butterfly effect. The butterfly effect is a theory that states that small changes or conditions can result to have a larger difference in a larger state. For example, small winds in the Pacific Ocean accumulating to cause massive waves near the shore. This relates to bioaccumulation, which is the accumulation of toxic substances throughout the food web. Simply put, pesticides are sprayed onto weeds, inadvertently hitting flowers, pollinators transfer the chemicals when they pollinate, pollinators are ate by insectivores and the concentration of chemical substances increases as it goes up the food chain. Now, the food chain ends with us, humans, which means that humans should get the highest concentration of the chemical substance. Over our lives, theses concentrations build up in our bodies and cause illness and side effects. DDT is an example of an organic compound that is able to bioaccumulate. During World War II, DDT was used to prevent soldiers from contracting malaria. After the war, DDT was sold as the best man known insect removal pesticide. DDT was pushed by Chemical Manufacturing Corporations because it was making millions and people believed that it was harmless. Until, Rachel Carson began noticing the abuse of chemical substances on the environment. In her book, Silent Spring, Carson argues against the over abuse of chemical substances because it is beginning to have effects on nature. Carson focused on the effects of DDT and received hateful criticism for it; however, it did not stop her because when her book was published it shed light on DDT. Carson died soon after her book was published but her work helped in banning DDT in the United States. Thanks to Rachel Carson, we do not have to worry about the hazards of DDT. Well, that is the end of this blog folks. Hope you enjoyed it. Also, look at the hilarious yet disturbing picture of a man spraying DDT.
