Unformatted text preview: 3) populations often face trade-offs between increasing nutritional intake vs. avoiding pathogens Classic examples of the last point: the use of "night soil" (human feces) for fertilizer nnincreases agricultural productivity while elevating risk of disease transmission; crop irrigation can increase rates of water-borne diseases like schistosomiasis; interaction of sickle cell and agriculture in W. Africa (see below) Thus, examining nutrition and disease together can reveal some very interesting ecological interactions Case studies summarized here also illustrate interaction of genetic/physiological processes with behavioral/cultural ones Thus one can consider the ecology of disease and nutrition in relation to broader conceptual issues re human adaptive strategies...
