Biology is the scientific study of life.
At no time in history has biology been so visible and so important to human life and the future of our planet than at the present. The study of biology has vast applications - in understanding one's own body, in grappling with the ethical questions that face humanity, and in understanding the interdependent web of living organisms on the planet and our need to help protect the delicate ecological balance that sustains us all. Today the biological sciences are experiencing a revolution. Important discoveries occur almost weekly as scientists and their students around the world develop and use new techniques, theories, and approaches. The University of Toronto has hundreds of faculty conducting research and teaching courses in the biological sciences.
