Duties to other humans concerning species are insufficient. Humans can also have duties to species as historically persisting forms of life. Engineers have a tendency to think of wild nature as undeveloped, raw, even waste. To the contrary, natural systems, characterized by speciation, are engineering projects worthy of admiring respect--in the sense that they represent inventive, ingenious, trial and error solutions to problems in survival.born digitalarticleseng©1987 National Association of Environmental Professionals.Copyright and other restrictions may apply.
