Water Conservation

What cycle does water go through? What pollutants can it gather along the way? What are the sources of water pollution? Who treats our water? Is water a public good or a commodity? Where does bottled water come from? Is it better than tap water? What happens to water in countries that don't regulate its quality or can't afford to treat it? What innovations allow for the affordable collection and treatment of water? We will ask those questions through this unit, and attempt to answer them. The 2008 award winning documentary FLOW by Irena Salina will be the base for our conversation on issues surrounding water conservation:

The Production of Electricity

As the industrialized world moves toward an all electric energy source, the class will learn how electricity is produced, stored, transported, and used. We will look at traditional means of producing electricity: diesel, coal, nuclear, hydroelectric, as well as more sustainable alternatives: wind, and solar. We will look at the advantages and drawbacks of each technology. The students will be introduced to the concept of "the Grid", and its elementary functioning. We will also discuss storage: batteries, flywheels, pumped hydro-power, etc.. Finally, we will discuss means by which we can reduce or mitigate our use of electrical power.

To ground our exploration and discussions, we will watch the Nova documentary Search for the Super Battery, and learn about the chemistry and physics behind the functioning of an electric battery:

The Production of Consumer Goods

To explore the sustainability challenges facing the production of consumer goods, we'll focus on one industry that touches us all: the fashion industry. We've started to watch The True Cost, a documentary by Andrew Morgan. As we unpack this film, our conversation will lead us to talk about consumerism, outsourcing production, externalizing cost, sweatshops, workers rights, social and environmental impact, GMOs, organic farming, Fair Trade practices, economic justice, etc.

Modern Sustainability Challenges: Farming

This quarter we'll explore sustainability challenges in the modern world. We'll focus on four areas: farming, the production of consumer goods, the production of energy, and fresh water management.

To guide our first subject of investigation, we'll watch and discuss Ken Burns' documentary The Dust Bowl, which depicts the agricultural development of the American Great Plains in the early 20th century, the ensuing catastrophic collapse of this ecosystem, and the American government's efforts to restore the land's integrity through innovations in soil conservation and land management.

Presentations

 (AD and GM demonstrate what a good presentation looks like)

You are going to research material for a presentation next class on a domesticated plant or animal of your choosing (e.g. bees, cows, grapes, goats, apples, cats, cotton, camels, strawberries, chicken, rice, sheep, tomatoes, silk worms, potatoes, etc. – we already presented wheat and corn). You can work alone or with one partner.

Each presenter or group of presenters must find the following information for their presentation:

1 – The name and a picture (on cell phone or flash drive) of your domesticated plant or animal.
2 – The name and a picture of its wild ancestor.
3 – Its place of origin.
4 – When it was first domesticated and by whom.
5 – When it was first transported on each continent.
6 – An anecdote about this plant or animal.

The Neolithic Revolution

We saw the sustainability challenges facing hunter gatherer societies, and notably the rapid hunting to extinction of most megafauna worldwide. The next chapter of our story brings us to an innovation that would have a profound effect on the ability of people to feed themselves over the long run, without depleting their resources: agriculture, which came with the domestication of animals and plants. 

Read Wild Thing on Aeon by Jacob Mikanowski, about the domestication of animals, and answer questions.

Reading: excerpt of The Sixth Extinction

- Read what you can of Chapter XI of Elizabeth Kolbert's The Sixth Extinction at home (for 30 minutes maximum - after that it's up to you whether you want to keep on reading or not). Note that I have included chapter XII as well because I thought you might be interested in reading it.
We'll discuss chapter XI next class.

Chapter XI looks into the causes of the loss of the Pleistocene megafauna and its consequences for the lanscape.
Chapter XII explores the possible reasons for the disappearance of archaic humans such as Neanderthals and Homo Erectus, who had populated Africa and the Eurasian continent before modern humans, and cohabitated with them for several thousand years.
