6. Missing Moths (Peppered Moths)
The large majority of the peppered moth population before the Industrial Revolution in England(around 1850) were light colored.
As a result of the many industries burning fuel, local vegetation became darker because of the air pollution.
The population of the moths began to change with the number of dark moths increasing while the light colored moths’ population decreased.
Most recently, as industries try to use cleaner fuels and cause less population, the bark of trees began to lighten again and the population of the light colored moths began increasing.
