This article is about the research done by a scientist and his team in a laboratory in California. They discovered that the male frogs that are raised in a tank that has a certain chemical changed from male to female. Hayes, the scientist, discovered this change and told this happend by the chemical called Atrazine,which is used to kill plants like weeds. This chemical, causes the change of sex: the male frog changes into a female, not only in its behavior but also the organism changes. The male frogs that are put in the tanks with attrazine have low levels of testosterone and don't attract females. The organization EPA, Environmental Protection Agency, is in charge of the human health and the enviroment. However, the organization approves the use of Atrazine in higher levels than what Hayes tested in his lab. Tim Pastoor, another scientists who works for the company that makes Atrazine said Hayes was wrong and that Atrazine is safe. .
The article interested me because it talks about the frogs and theirsex change. We studied genetical modification in class, but this modification is always done on purpose to improve an organism. I never thought that this would happen not just in the laboratory but in an animal's natural habitat. This is happening in the US but this could happe in all the world because we don't know if Atrazine is being usied in other parts of the world. So that is very interesting. Before I didn't know about the Atrazine and I didn't know about EPA.
This article has a connection with my life because all things that affect the ecological balance can affect my life. For example, this frog eats a mosquito ora fly and if this frog stops reproducing, it can become extinct, so if that happened the mosquito or fly could reproduce without being eaten so there would be a lot, and the animal that eats this frog could die if it doesn't have food, or it would have to find other animals to eat. So that is why the problem with this frog changing sex affects my life.
