Cone, Maria. "New Study: Autism Linked to Environment." ScientificAmerican.com. Scientific American, 9 Jan. 2009. Web. 21 Sept. 2011.


    This article is about the recent increase in autism and whats causing it. It's based on a study that shows that chemicals and pesticides in the environment could be causes of the increase in autism. The author's intent is to inform the readers of these new findings. The audience is anyone interested in this topic. It is supported by a scientific study. It wasn't biased at all because it was all based on study.
     This wouldn't be the most ideal topic for me, I'm not sure there is enough to write an essay for. It may be a good article for people writing a paper about the effects of chemicals to the environment and to humans, but it would only be useful as  a small support.
