Rachel Carson

     Rachel Carson was a shy and reserved woman who contributed much to Environmental Science. After Rachel Carson wrote the book Silent Springs much controversy arose in the field of Environmental Health. Many people did not know much about pesticides in the environment and harmful chemicals so they just brushed off what Rachel Carson had to say. Many skeptics played on stereotypes of her sex and said she was being over-dramactic because she was a woman.
     Rachel Carson was able to show the pesticides were ineffective because the insects would build up a resistance. So the more and more we were spraying these harmful chemicals on plants and food supply the more harm we were doing to ourselves. Some of the these pesticides would collect in the fats of humans and later on cause health issues that could possibly lead to death. Without Rachel Carson taking the time to write her book Silent Springs and pointing out how these pesticides were having a negative effect on our environment and health we could still be polluting the environment and ourselves.

Seasonal Allergies

When you think of global warming you probably do not think of seasonal allergies. Well, hopefully after you read this blog you will see why these two are connected. As the years past by we can see the trend of the planet's temperature rising. Because the Earth's temperature keeps rising we are seeing longer spring and summer months and shorter fall and winter months. This issue with having a longer spring is seasonal allergies are prolonged also. There is less frost and earlier blooming which means longer periods of pollen which triggers allergies for many people including myself. Symptoms of seasonal allergies range from but are not limited to sneezing, itching, red eyes, and coughing. I do not know about others with seasonal allergies but a lot allergy medicines do not work well for me so longer periods of pollen is not an exciting or welcomed thing. Also, for a lot of seasonal allergy sufferers after days of repeated "allergy attacks" this could lead to a sinus infection. If the sinus infection is serious enough you may need to go to the doctor to get antibiotics. Overall, global warming is causing seasonal allergies to be prolonged and there will be a rise in sinus infections because of prolonged allergy periods.
