About 70% of our planet is covered by oceans and seas: large, full of life and mysterious.
They are a source of food, way of transportation, oxygen producer, and more.

But the sea is in danger: overfishing, plastic waste, acidification, species extinction.
We need to better understand the marine life and deal with it in a sustainable way, because our life is closely linked to the sea. If it is sick, we cannot stay healthy.

Why are we overfishing the oceans? Why are we cutting trees faster than they're growing? Why did the Easter Islanders resort to cannibalism? And how did an economics professor dad stop his teenage sons from wasting his whole paycheck on soda pop? It turns out that all of these are examples of the Tragedy of the Commons. This economic theory explains why, when a resource is collectively owned, there is no incentive to use it sustainably. This explains why many natural resources are depleted, even though that makes everyone worse off.

The year is 2050 and your once-idyllic beachfront vacation home is now flooded up to the second story. The crab your family has enjoyed every Christmas for as long as you can remember has now become an endangered species. The oceans have changed. In Earth 540, Oceanography for Educators, we explore the mechanisms that lead to sea level rise and ocean acidification. We strive to understand how natural processes such as ocean currents, the gulf-stream, tides, plate tectonics, and the Coriolis Effect, affect our oceans and ocean basins. We then predict how man-made issues such as climate change and overfishing will affect our beloved waters and our livelihoods. Want to see into the future? Then this course is for you!

The ocean's resources are slowly being depleted. This curriculum examines the issue of overfishing and its impact on both the environment and human life. In developing sustainable solutions, the students address the driving question: "How can we as youth, sustain the future of the world's ocean through our actions today?"

Giant clams are no myth. In New England, people love clam chowder, but in the Pacific, some of the clams are as big as a suitcase! In this video filmed in Micronesia, Jonathan goes in search of Giant Clams. These clams are so big that people used to think they caught people...and it almost looks like they could. It turns out that the real problem is that too many people are eating the clams. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This kit covers a historical overview of American representations of endangered species from the slaughter of the American buffalo to Palm plantations in Sumatra. It compares conflicting constructions about human/animal relations, rainforest biodiversity, the Northern Rockies gray wolf, frogs and Atrazine. Students decode how the relationship of animals and humans has been portrayed and passed on from generation to generation.

Simulating the Tragedy of Commons illustrates for students to how sustaining our natural resources requires conservation and the cooperative use of those resources.
