questionHow many citizens of Haiti does it take to equal the ecological footprint of the average citizen of the United States?
answerTwelve citizens of Haiti equal the ecological footprint of the average U.S. citizen.
questionNearly 50% of the land on our planet is currently used for agriculture, with very little more agriculturally usable land available. If everyone on the planet had an ecological footprint the size of the average citizen of the United States, then ________.
answerwe would need at least two more planet Earths to feed and support everyone.

questionRuben has a new puppy named Paddington and wants to feed him the best possible food. He decides on an experiment where he will feed Paddington the very best canned food plus a dietary supplement of vitamins recommended by a veterinarian. Which of the following best describes Ruben's project?
answerThis is not an experiment-there are no controls or replicates.

questionGeothermal energy, wind energy, and solar radiation are all examples of ________.
answerrenewable environmental resources.
questionWhich of the following best embodies the qualities of a scientific theory?
answerStudents who study for their environmental science exams will perform better on those exams than those who do not.
questionEcosystems are ____.
answerare economically valuable services provided by natural systems
questionThe concept of sustainable development includes ________.
answerthe needs of future generations
questionYou 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 also practiced contraception. These actions all indicate that ________.
answerthey truly practiced sustainability.
questionSustainability _____.
answerinvolves using resources without compromising future availability.
questionPesticides use ______.
answermay be a necessary part of modern technological agriculture
questionIn a controlled experiment, ____.
answerthe researcher controls for the effects of all variables except one
questionQualitative data ____.
answercan be acquired in the detailed examination of personal interviews or observations.
questionA pharmaceutical company wishes to study a possible new headache medicine. They are doing human trials with 1000 volunteers who experience frequent headaches. The researchers will need to ________.
answercontrol for the type of headache - stress, migraine, or other causes.
questionA study's results are deemed worthy of acceptance into the body of scientific knowledge if they are published in journals which ________.
answeruse the peer review process.
questionPablo 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 to test their hypothesis that the local veterinarian's special dog food mix will enhance growth and development. Each student adopts a puppy from the local pound. Pablo plans to feed his shepherd-mix dog the special diet, while Johanna plans to use generic dry kibble from the supermarket for her bulldog. The independent variable in this study will be ________.
answerthe type of food the dogs receive.
questionOne dependent variable in this study will be ________.
answerhow much the dogs grow
questionWhen they write up their initial proposal, the instructor will probably ________.
answertell them they have some serious problems with the proposal, but it is fixable if they are willing to take care of more dogs.
questionPablo and Johanna have too many ________.
answervariables that they didn't control and not enough replicates.
questionAfter 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, for a total of 24 puppies consisting of 12 females and 12 males. In order to have two groups of puppies (control and experimental), Pablo and Johanna should ________.
answerfor several months, weighing and measuring the pups every week
questionIf the puppies in the experimental group gain, on average, 3 pounds more than those in the control group over a 4-month period and seem healthier and more energetic, then ________.
answerthere is a high probability that the veterinary diet is better than kibble for puppies.
questionWhy is it important to understand our interactions with the environment? What will studying environmental science enable you to do?
answerwe depend on environment for air, water. food, and other necessities. More understanding will give us knowledge on the changes and problems of our natural environment and how an individual can positively play their environmental role on earth.
questionDifferentiate between environmental science and environmentalism. Define each term and explain how they are similar and how they differ.
answerEnvironmental science is the actual study of the environment and our interactions. It's somebody who studies the environment in a scientific manner. Environmentalism science is the concept on how humans prevent environmental problems. they are concerned with the protection and preservation of the natural environment Both have same topic however participate in different roles. An environmental scientist conduct research to subside, identify, and eliminate hazards that affect people, wildlife, and their environments Environmentalism is more concerned with the protection and preservation of the natural environment.
questionCompare 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?
answerThe natural sciences are made up of disciplines that study the physical and biological facets of the natural world and their interactions with each other. These disciplines rely on all types of studies that generate mainly quantitative data, allowing scientists to acquire and interpret information about the natural world. The social sciences are made up of disciplines that study human attitudes, behaviors, and interactions. The scientists in these disciplines mainly collect qualitative data using a variety of research techniques that are similar to natural scientists. Studies that examine how cultures perceive an environmental concept may be used to implement environmental policy. Because environmental problems involve accurate assessment of the scope of the problem by which policy that affects humans is devised, both types of sciences are needed to be a part of environmental science.
