E1
Evidence of human activity is found in strange times and places, and a new perspective on a biological activity known since the nineteenth century.
E2
Five discoveries are probably related to potential warfare and one possibly to wildlife.
E3
Major natural anomalies and varied human activities are investigated.
E4
We investigate two examples of human activity in the U.S.A., one in Africa and one in Asia, with two natural phenomena where ice is a major factor.
E5
We investigate two examples of men at war, and two engaging with water, but another vision is in the eyes of the beholders, and the last phenomenon is a severe natural event.
E6
We investigate one natural phenomenon, four shapes that look like being of human origin, and monitor one example of human origin and current destruction.
