Question

Quizplus · Accepted Answer

Life on earth has been sustained through millions of years of ice ages and long warming periods. While the exact age of the earth is estimated to be around 4.5 billion years, life is believed to have originated around 3.5 billion years ago. Throughout its history, the earth has undergone multiple ice ages and long warming periods, but life has persisted and adapted to these changes. Humans are a relatively recent addition to this long history, appearing only around 200,000 years ago. Renewable resources, while important for sustaining life, have not been the primary reason for the sustained existence of life on earth.
