Over the past few decades, the injurious effects of human behaviour on Earth's natural systems have become increasingly obvious. There can be little question that ecological changes leading to extinctions of species and loss of habitat pose a threat not only to our health, our prosperity and even our existence, but to the biosphere as a whole. Our failure to change our ways must be acknowledged and confronted. With its expertise in many domains of human endeavour, St. Thomas University is well prepared to help students interrogate the social processes that promote both our degradation of Earth and our persistence in such destructive behaviour.
