Passmore argues that there is urgent need to change our attitude to the environment, and that humans cannot continue unconstrained exploitation of the biosphere.

The Spirit of the Soil challenges environmentalists to think more deeply and creatively about agriculture. Paul B. Thompson identifies four `worldviews' which tackle agricultural ethics according to different philosophical priorities; productionism, stewardship, economics and holism. He examines current issues such as the use of pesticides and biotechnology from these ethical perspectives. This book achieves an open-ended account of sustainability designed to minimise hubris and help us to recapture the spirit of the soil.
