All you need to get started finding information and resources for Environmental Sciences.
The 2 locations within the Libraries that are most likely to have the books you want are as follows:
Sydney Jones Library
Environmental Science, Geography and Planning books can be found on the main shelves in the Grove Wing. The class number of the book you want will identify the floor it is located on.
Harold Cohen Library
Ocean Sciences, Geology and Geophysics, and Ecology and Marine Biology books can mostly be found in the Silent Study Room and on the Ground Floor Rear.
