Where does the University of Dayton get its energy?
So most of the electricity nationally, and virtually all of that for UD comes from coal?

What are the most common methods of mining?
Are there ecological implications of this kind of mining?
What happens to mine land?
And golf!!
Groundwater Contamination
Acid Mine DrainageAcidity in AMD is comprised of mineral acidity (iron, aluminum, manganese, and other metals depending on the specific geologic setting and metal sulfide) and hydrogen ion acidity. Approximately 20,000 km of streams and rivers in the United States are degraded by AMD. About 90% of the AMD reaching streams originates in abandoned surface and deep mines. Since no company or individual claims responsibility for reclaiming abandoned mine lands (AML), no treatment of the AMD occurs and continual contamination of surface and groundwater resources results.

Top ten cotton producers — 2007(million 480-pound bales)
People's Republic of China 35.8 million bales
India 25.3 million bales
United States 19.2 million bales
Pakistan 9.0 million bales
Brazil 7.2 million bales
Uzbekistan 5.5 million bales
Turkey 3.2 million bales
Greece 1.4 million bales
Turkmenistan 1.3 million bales
Syria 1.2 million bales

Conventionally grown cotton uses more insecticides than any other single crop and epitomizes the worst effects of chemically dependent agriculture. Each year cotton producers around the world use nearly $2.6 billion worth of pesticides -- more than 10% of the world's pesticides and nearly 25% of the world's insecticides.
Cotton growers typically use many of the most hazardous pesticides on the market including aldicarb, phorate, methamidophos and endosulfan. Cotton pesticides are often broad spectrum organophosphates--pesticides originally developed as toxic nerve agents during World War II--and carbamate pesticides.

Ecological Implications of Food
I am an ecologist…
I study the sustainability of slash & burn agriculture in Indonesia.
What impact does this method have on biodiversity?
Is it sustainable over the long-term?
