Saving Our Oceans
Discovery Questions:
1. Name and describe the physical and biolocial components of another reef ecosystem around the world? For one point extra, turn in an ecosystem map of a coral reef habitat.
2. What human activites do scientists contribute to the decline of coral reefs?
3. Why are sharks considered keystone species of many reefs, according to the article?
4. How do environmental scientists monitor the health of coral reefs?
5. What are the economic complexities around the establishment of a marine reserve, as explained in the article and your research?
6. What is the role of the Endangered Species Act and conservation organisations in preserving our oceans?

Super Eruptions and Climate
Over the winter break I had the opportunity to go on a geology tour and visit a volcano. One of the features I witnessed, was the intrusion of dikes into the monzogranite formation of the area. Coming back to school and starting the geology unit for AP Environmental Science got me thinking about the importance of volcanoes and how they effect the environment. While they can be destructive, are there any benefits to the environment? The blog this week asks students to explore short-term and long-term benefits to the environment of volcanic eruptions.
Questions:
1. What are the characteristics of a volcanic explosion?
2. What are some of the most destructive volcanic explosions in the history of the planet?
3. What is the relationship between volcanoes and climate change throughout history?
4. What are some of the short-term and long-term benefits of a volcanic explosion to the environment? Look at climate, soil, biodiversity, and human agriculture.
5. How did the Toba super eruption effect the evolutionary history of humans?

Wolves in Yellowstone
Was flying to Chicago this weekend and read on the plane about this conservation group in Minnesota that was monitoring and preserving wolves. It was a good piece of luck, considering I had just showed the National Geographic movie Wolves: A Legend Returns to Yellowstone. The movie discusses the reintegration of a wolf pack into Yellowstone park and also discusses conservation management techniques and radio telemetry used to monitor the wolves. Searching blogs and discussion groups on the internet shows that it is still a topic of heated debate between local ranchers, environmentalists, park officials, and eco-tourism businesses.
1. Discuss one pro and one con of reintroducing wolves into Yellowstone from one of the following perspectives (rancher, environmentalists, park ranger, eco-tourism owner).
2. Discuss the steps environmentalists take to ensure the successful reintroduction of wolves.
3. Explain how radio telementry can be used to monitor wolves.
4. Discuss what data can be obtained from such a monitoring system.
5. What dangers to the wolves face (human, climate, predators, other wolves)?

Overfishing
A recent NPR.org podcast reports an increase in overfishing, mainly due to the U.S. and Europe's desire to eat more fish. This got me wondering how many other countries are jumping on the "eating fish is healthier" bandwagon and contributing to the rapid decline of global fisheries. A quick search of Google News found an article summarizing a series of studies that local taboos in most developing countries have stymied overfishing of local reefs. In this light, then...
Questions:
1. List one developed country and one developing country that are to some extent contributing to the decline of global fisheries. Describe the difference between these two countries in terms of their GDP. What is their import/export of global fish stocks?
2. Describe one cultural practice in a developed country that is contributing to the decline of global fisheries and one cultural practice in a developing country that is helping to prevent the decline of global fisheries.
3. Describe two types of technology that are being used in commercial fishing and for each type of technology describe one environmental problem that arises from its use.
4. What is one legislative law that regulates global fisheries, and explain under what circumstances this law is suspended and/or reinstated.
