Mammals & Timescales

“Humans are exterminating animal and plant species so quickly that nature’s built-in defence mechanism, evolution, cannot keep up. An Aarhus-led research team calculated that if current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3 to 5 million years to recover.

Great Acceleration

“In tracking the effects of human activity upon the Earth, a number of socioeconomic and earth system parameters are utilized including population, economics, water usage, food production, transportation, technology, green house gases, surface temperature, and natural resource usage. The Anthropocene is typically depicted as following the Holocene, to emphasize the central role of humankind in geology and ecology. Since 1950, these trends are increasing significantly if not exponentially.”
