The chapter describes an approach used to introducing bioethical theory to applied biology undergraduates over a number of years. It employs a framework for ethical analysis, the ethical matrix, which is designed to assist students in:
• Identifying ethical concerns
• Examining information and opinions relevant to those concerns
• Making considered ethical judgements on these concerns, and
• Through class discussion, comparing these judgements with the views of others.
In the form in which it used here, the matrix applies the three ethical principles of respect for wellbeing, autonomy and justice to the interests of defined groups who might be affected by the application of a novel agricultural biotechnology. To illustrate the use of the matrix, ethical issues raised by the employment in dairying of the milk yield-boosting hormone, bovine somatotrophin (BST), are assessed by examining claimed impacts of its use on these three principles as they affect dairy farmers, consumers, treated dairy cows and the ecosystem. The example chosen highlights critical concerns, since BST is employed commercially in the USA but is banned in the EU. It is stressed that in order to reach sound ethical decisions, in addition to a suitable framework, it is also necessary that assessments be performed by competent moral judges, whose attributes are defined.
Although illustrated here in relation to an agricultural biotechnology, in principle, the Matrix can be applied to any field of human endeavour in which choices involving a range of interests have to be made.
