A response of the engineering profession to the challenges of security, poverty and under-development, and environmental sustainability is described. Ethical codes, which govern the behavior of engineers, are examined from a historical perspective linking the prevailing codes to models of the natural world. Anewethical code based on a recently introduced model of Nature as an integral community is provided and discussed. Applications of the new code are described using a case study approach. With the ethical code based on an integral community in place, a new design algorithm is developed and also explored using case studies. Implications of the proposed changes in ethics and design on engineering education are considered.
