c. Sixty-six million years ago, a massive asteroid struck Earth, resulting in the extinction of three-quarters of all plant and animal life, including dinosaurs.
d. Drainage patterns across the globe are altered due to dams and road building.
e, Atmospheric CO2 has increased more quickly, and to higher concentrations, than during any other part of geologic time.
