B-rock the anthropogenic era started 8,000 years ago not in 1950 or 150 years ago like some believe. The anthropocene theory states that humanity has been affecting the environment in a detrimental way since the Neolithic period and somewhat before. Everything from the clearing of forests to the growing of rice (rice paddies release methane) and mass extinction of animals through overhunting is part of the anthropocene. The industrial revolution accelerated the release of CO2. We probably would have been in a full blown ice age by now if it weren't for anthropogenic, that is man made, release of greenhouse gases.
