We feel that making questions about each of the chapters that we have learned so far is a very good way of better understanding the concepts that are found in the book. By doing this we learn much more than we normally would, because in order to prepare the questions we need to read the book carefully and try to better understand all the different concepts, graphs and information found in the book.

As the title suggests the first chapter serves as some kind of an introduction. It defines such terms as environment and environmental science and illustrates certain environmental issues and the outcomes of human impact on the nature.

After preparing these questions we feel that we have learned a lot more as this process took a lot of time and effort, but in the end was worth it as we are now more aware of the different ecological concepts and processes that go on in the world. This has helped us a lot, but we think that anyone who is able to answer these questions knows the content of the book and is well prepared.
