Our affluent western lifestyle will soon exceed the limits of the earth's ability to sustain it, warns Floris van den Berg; we must learn to do things differently, or face a worldwide environmental collapse. A university lecturer on environmental philosophy in the Netherlands, van den Berg here proposes a new perspective, called universal subjectivism, which takes into consideration the universal capacity for suffering. When we drive to work, board a plane for business or vacation, eat meat, or use plastic bags in stores, we inflict avoidable suffering on other living things. Van den Berg argues that the world can be organized to ensure more pleasure, beauty, justice, happiness, health, freedom, animal welfare, and sustainability.
