Ecological Implications of Energy
Where does the energy your use come from
http://www.eia.doe.gov/cneaf/electricity/epa/figes1.html
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?
Where does that coal come from??

What are the most common methods of mining?
Are there ecological implications of this kind of mining?
What happens to mine land?

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.

Ecological Implications of Food
Three points
(a) Eating is an Ecological activity that directly connects you to ecosystems and landscapes
(b) Industrial agriculture violates a basic ecological law, and engages directly in evolutionary processes
(c) Ecological consequences of food choices are far reaching and feedback directly into human society.
“The passive American consumer, sitting down to a meal of pre-prepared or fast food, confronts a platter covered with inert, anonymous substances that have been processed, dyed, breaded, sauced, gravied, ground, pulped, strained, blended, prettified and sanitized beyond resemblance to any part of any creature that ever lived….Both the eater and eaten are thus in exile from biological reality” Wendell Berry (1990) From : What are People For (North Point Press)

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.

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?
