Built in 1991, the ESB won an award for design. It is built to make people aware of the earth, the environment and all living things, and the importance of not jeopardizing it for future generations- that humans are not better than nature, but part of it. A design highlight is the green roof, which is used to grow produce for the Trent student-run Seasoned Spoon Café. The centre of the building, where the three wings converge, contains a global sphere (envirosphere), with its axis pointing 23.5 degrees (mimicking Earth), with a skylight above (eye of the universe). The ESB also houses the undergraduate Geography Department, the Graduate Environmental and Life Sciences Program, and the Bachelor of Arts and Science office.
