Dysgenics

Dysgenics is a term used to describe the continuing decline of a population's total health and wellbeing, which is caused by genetics. This happens when people with less healthy genes (genetics is how our body looks and behaves) have more babies than people with healthier genes. This causes the population to have more unhealthy genes overall, which will lead to more diseases, disabilities, and problems over time.
