Exam 1: Science and Sustainability: an Introduction to Environmental Science
Differentiate between environmental science and environmentalism. Define each term and explain how they are similar and how they differ.
Environmental science is the pursuit of knowledge about the workings of the environment and our interactions with it. Environmentalism is a social concern focused on protecting the natural environment and, by extension, humans, from undesirable changes brought about by certain human choices.
Environmental scientists and environmentalists study the same issues, but environmental scientists use an objective scientific approach to understanding environmental problems. Environmentalists, on the other hand, may use dramatic and often emotional approaches to alter the political and social understanding or to educate the public about environmental problems.
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 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.
-When they write up their initial proposal, the instructor will probably ____________.
B
Why is it important to understand our interactions with the environment? What will studying environmental science enable you to do?
We depend on the environment for air, water, food, shelter, and everything else. We are capable of modifying and harming the environment whether we intend to or not. Understanding our interactions with the environment is the essential first step toward devising positive, sustainable solutions that will allow future generations to enjoy a rich and full world. Studying environmental science will give us the tools we need to evaluate information on environmental change and to think critically and creatively about possible actions to take in response.

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, 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 _________
