I think we should absolutely accept the Anthropocene epoch to the geologic time scale. To not actively address and take into consideration of humans effect and alteration of the environment on the time scale would be ignoring the cause of a extremely major factor in the rapid changing of the earth in the past few hundred years. As to what time we should start to take this into consideration for, it should be somewhere between the beginning of the exploration age and the industrial revolution. From how I see it, this is one of the most important and large factors in the rapid alteration of the environment. With the timber industry booming in the exploration age to build ships and new buildings in settlements, this created a large deficit of trees during this time, causing a large environmental impact of deforestation. In the industrial era, it’s a bit more obvious and straightforward as to what the negative impacts of humans on the environment is, with all the burning of coal and harvestation of natural resources.
I think the need people feel to conform to whatever their social peers believes reflects a sense of sheeping that is common with humans. This conformity, however, can be catastrophic in the climate sciences arena due to lawmakers and legislators feeling this influence from their peers and parties to either agree or disagree with whatever opinion the aforementioned believe in themselves. This leads to not much being done about the catastrophic effects we have seen result from years of neglect for our actions on the environment and climate.
