Long-winded Spiel:
The current obesity epidemic highlights the disparity between our biological capabilities and technological realities. Over millions of years, humans
evolved to eat a diet primarily of low-carbohydrate foods (before agriculture, our ancestors foraged for vegetables and fruits) and the occasional
intake of meat (when the hunt was successful). Additionally, our pre-agricultural ancestors got quite a bit of exercise, walking 10 to 15 miles a day
while foraging and hunting in bands. About twelve thousand years after the invention of agriculture, our technology is able to produce food so
cheaply that even the lowest on the social ladder are able to purchase an over-abundance of calories. Additionally, technology also allows us to get
by with spending very few of those calories in the form of work or exercise. No longer do we need to wander the forests foraging for roots – we hop
in the car and drive to McDonald’s for a super-sized value meal. Thus, we have the current obesity epidemic in Western countries. Technology
allows us to live in an environment foreign to that for which we are evolutionarily equipped, and this has serious heath and societal consequences.
Cancer offers another example. Our technology has several nasty externalities, one of which is the production of any number of carcinogenic
pollutants into our environment. We are not evolutionarily equipped to live in a carcinogenic environment and thus we experience cancer has an
adverse health effect of technology. Additionally, technology is allowing us to extend our lives past the point for which was evolution allowed us to
reach. Because our bodies are not evolutionarily equipped to living past 65, our bodies experience all sorts of failures as we age, among which
cancer is chief.
Finally, considering mental health, depression is also an example. We evolved as social animals, hunting and foraging in groups to maximize food
intake for all through group cooperation. As such, the evolutionary process selected those genes that promoted social cohesion and sharing, for the
primitive survival of our ancestors depended on it. Technology has drastically transformed society such that social cohesion and sharing are no
longer needed for our physical survival. However, the slow pace of evolution may mean that we still need social cohesion and sharing mentally. On
the individual level, some brains cannot deal with this disparity and become chemically imbalanced causing depression or other mental disorders. On
the societal level, institutions such as religion, nationalism, and racial identity, evolve as an outlet for our need of social cohesion. These
institutions however, have been anything but good for the long-run health and viability of humanity. Depression and mental health problems are the
result of technology changing our social environment into something for which our brains are not biologically adapted.
The problem boils down to the race between environmental change and biological change. Our technology has had an Agricultural Revolution and an
Industrial Revolution that has drastically changed our environment faster than the evolutionary process can create biological change. We need a
Genetic Revolution to bolster the speed of our biological change to keep pace with our technological change. In the future, active genetic
engineering may be necessary in order for humans to adapt to their environment at the same rate at which that environment changes. Else, the
environmental changes caused by our technology may mean the end for humanity in the long-run.
Will genetic engineering be the Savior of Mankind, allowing humans to adapt and at the same rate of technology? I argue yes. We already “play
God” with our environment, and to keep up we must “play God” with our genetic make-up in order to preserve the long-run health of humanity.
Technology hurts our well-being, but can also be used to enhance it.
