Environmental Science: A Canadian Perspective provides students with an accessible, interdisciplinary and engaging introduction to the study of the environment that is grounded in biology. With this Fourth Edition the author has once again crafted a text that strikes the proper balances between principles and applications, local and global perspectives, and rigor and simplification. With each page meticulously updated, this text includes the latest environmental issues relevant to Canada and its international context. There is also an entirely new CBC Video Library available with this edition designed to reinforce the key concepts presented in the textbook and bring the subject to life for students.
