An instance showing the difference between an act of omission and the commission of an act is the difference in withholding the truth and voicing a lie. Both an act committed and an act of omission can change the result of a circumstance.The International Commission on Stratigraphy, a group of geologists within the International Union of Geological Sciences, is the scientific body that officially decides when epochs begin and end.
The GSSP is located along the northern bank of a small stream that feeds the tributary to Sheinton Brook in Whitwell Coppice, 500m north of the hamlet of Homer at SO 6194 0204. The GSSP lies within the upper half of the Apedale Member of the Coalbrookdale Formation. The GSSP lies within a continuous mudstone sequence.

The Anthropocene is intriguing scientifically, fascinating intellectually, and deeply disturbing politically, socially, economically, and ethically. We must learn how to co-exist sustainably with the rest of nature in what is emerging as a new planetary state. To do so, we must first understand what "Anthropocene" means in all its dimensions.International Quaternary Association (INQUA) Commission on Stratigraphy regarding the stratigraphy of the Quaternary, and with the Commission for the Geological Map of the World (CGMW) in Paris regarding standardisation of chronostratigraphy and its colour scheme on charts, as well as producing the ICS International Chronostratigraphic Chart.
