We have evolved defenses against pathogens, and these defenses can be strengthened by manipulation. Our social institutions must be designed to protect the health of individuals, providing clean water, adequate nutrition, and access to medical services. Living organisms are governed by a set of inherited instructions that are passed on from one generation to the next. Information encoded in the structure of DNA is expressed by the cell as proteins which shape the traits of the cell and the organism. Expression of traits is influenced by environment.
All organisms share a common genetic origin.
Changes in genetic information occur and may result in changes in traits that affect the interaction of the individual with the environment. Humans now have the ability to alter this information and quickly change specific attributes of living organisms. C. Overpopulation 1. The human species has continued to grow exponentially and is challenging the resources of the earth. Humans are dependent upon the primary productivity of other species.
