McKibben claims that the most important aspect of human nature is our ability to say "enough." Saying enough means claiming happiness and satisfaction at a certain point and no longer desiring further progress. Please select one area of human development where you feel we need to say enough. Describe the area and explain why it needs to stop where it is. It can be anything from building bigger and better athletes, to plastic surgery, to gigantic SUVs, to space exploration. Build a convincing argument. Please write 200-350 words. Keep in mind, bad habits are not an example of human development (for example, smoking or texting and driving). Development relates to scientific and technological advancements.
