Who is to blame for climate change? What exactly is the reduction of biodiversity, and why is it bad? Is damage to the environment bad only because of its effects on humans, or does ethics reach beyond humanity? How should we change our political systems to take into account the rights of non-human animals? The range of pressing philosophical questions of the environment has recently produced an outburst of rigorous work in philosophy of environment. In this course, students will join and take forward the discussion. The course forms a capstone, bringing together the different parts of philosophy students have studied: ethics, politics, epistemology and metaphysics.
