Humans have become a geological force from "summary" of Earth in Human Hands by David Grinspoon
The Earth has seen many changes over its long history, with shifts in climate, landscape, and biodiversity occurring over millions of years. These changes were usually driven by natural forces such as volcanic eruptions, asteroid impacts, and changes in the Earth's orbit. However, in recent times, a new force has emerged that is shaping the planet in unprecedented ways - humans. Unlike any other species before us, humans have altered the Earth's surface, atmosphere, and oceans on a global scale. We have transformed landscapes through agriculture, mining, and urbanization, leading to deforestation, soil erosion, and loss of biodiversity. We have altered the composition of the atmosphere by burning fossil fuels, releasing greenhouse gases that are driving climate change. We have polluted the oceans with plastic waste, chemicals, and oil spills, leading to dead zones and threatening marine life. These changes are not just temporary blips on the Earth's history but have the potential to leave lasti...
