Since oceans cover roughly two thirds of the Earth, and since oceans can demonstrate signs of ecosystem health and climate change, the U.S. EPA has watched the ocean for changes in their physical property for many years. From sea level height to ocean temperature to coastal flooding occurrences to surface temperature, the EPA has closely monitored changes in these properties as an indicator of climate change.
Just a reminder of last week’s post:
The United States has been using pesticides for decades to protect crops and livestock from disease, mold, insect damage and many other types of pesky organisms. According to the United States Geological Survey (USGS), roughly 540 million pounds of pesticides were used in 1964. How many pounds of pesticides were being used across the nation by 1993?
Answer: 1.1 billion
Technically, the term “pesticide” is a somewhat generic term to describe a substance that controls pests. Based on that definition, pesticides include herbicides, fungicides, insecticides and many more chemical solutions. Given the increase in the U.S. population between 1964 and 1993, and the growth in the number of viruses, fungi, bacteria and other organisms that could endanger the health of our crops and livestock, it’s not surprising that our use of pesticides rose significantly over that period of time.

It’s that time of year again – avoiding the Thanksgiving “Fatberg”
Thanksgiving is that special time of year that we gather together with family and friends to give thanks and experience traditions that are carried on through generations. Our Thanksgiving meal consists of: roasted turkey, mashed potatoes, stuffing, gravy and homemade cranberry sauce. We also serve the not-so-customary stuffed artichokes – a family favorite, passed down from my Italian grandparents. Continue reading Surefire Ways to Avoid Fat Gain During the Holidays
For the past few years, news reporters have used words like “developing” and “emerging” and “crisis” to describe perfluorinated compounds. When you see adjectives like this, you can’t help but think “how did we not know about these PFC things before now?”
The truth is, these compounds have been produced for decades – some, for over half a century – and their chemical and physical properties are well-known. The strength of the carbon-fluorine bond in these compounds makes them heat-, water- and stain-resistant.
