Exam 1: Science and Sustainability: an Introduction to Environmental Science

Read the following scenario and answer the question below. Pablo and Johanna have to do a yearlong study for their biology course. After some discussion, they decide to try comparing their dogs and the diet that they feed them. Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd-mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster -growing dogs. -When they write up their initial proposal, the instructor will probably ______________

Match the following: -Type of discipline describing environmental science

Use the figure above to answer the following question -Nearly 50% of the land on our planet is currently used for agriculture. If everyone on the planet had an ecological footprint the size of the average citizen of the United States, then .

Read the following scenario and answer the question below. After meeting with their instructor, Pablo and Johanna know that they need to change their experimental design. They contact a local puppy farm and arrange to do their study with 3-month-old litters of pups from four Irish setters, a total of 24 puppies, consisting of 12 females and 12 males. -Pablo and Johanna should probably run the experiment ______________

Use the figure above to answer the following question -The worldʹs average footprint per person is about 2.7 hectares per person. At that size, we are depleting our renewable resources 30% faster than they can replenish. The U.S. average footprint is 9.4 hectares, which is times larger than the average world footprint.

In general, natural resources ______________

Compare and contrast the types of knowledge gained and the research methods of natural and social sciences when considering environmental problems. Why do both types of disciplines need to be a part of environmental science?

You have read about the mistakes made on Easter Island. On Tikopia, another small island, the people acted in other ways. When they realized that the pigs they had imported were damaging the environment, they killed them all. They had to have permission from a chief to fish, which prevented overfishing. They practiced contraception. These all indicate that ______________

Choose the item that best matches each item of the following: -A scientific field of study

Use the assessment tool at www.ecologicalfootprint.com to calculate your ecological footprint. Once you determine the factors that evaluate your use of water, energy, waste disposal, transportation and food consumption, use the results of your specific ecological footprint to determine 3 specific actions which you can take to reduce the size of your ecological footprint. Make sure that your specific actions each fit into a different category (water, energy, waste, transportation, and food). Summarize your assessment.

Match the following: -Expectations of experimental outcome

Which of the following terms best describes the practice of environmental science?

By studying ancient civilizations, such as the Greek and Roman empires and the Angkor civilization of Southeast Asia, historians have concluded that these civilizations declined partly because of ______________

Advances in agriculture ______________

Name two transformative events of the past 10,000 years that caused human population size to increase. Describe each, briefly explaining the contributions that each made to human population growth. Include pros and cons of each.

Use the figure above to answer the following question -The average footprint per person has increased from 2.2 to 2.7 since 2008, and the footprints of many developing nations, such as India and China, have also increased. This means that .
