Anthropocene

File:Earth's_City_Lights_by_DMSP,_1994-1995_(large).jpgThe Anthropocene is characterized by human impacts on their environment, with ramifications for variables such as climate change, biodiversity loss, and global food insecurity.[20]The Trinity test in July 1945 has been proposed as the start of the Anthropocene.Summary of major environmental-change categories that cause biodiversity loss. The data is expressed as a percentage of human-driven change (in red) relative to baseline (blue), as of 2021. Red indicates the percentage of the category that is damaged, lost, or otherwise affected, whereas blue indicates the percentage that is intact, remaining, or otherwise unaffected.[79]Atmospheric CO2 concentration measured at Mauna Loa Observatory in Hawaii from 1958 to 2023 (also called the Keeling Curve). The rise in CO2 over that time period is clearly visible. The concentration is expressed as μmole per mole, or ppm.File:062821Yreka_Fire_CalFire_-2wiki.jpgFile:Bleachedcoral.jpgFile:Village_Telly_in_Mali.jpgFile:US_Navy_071120-M-8966H-005_An_aerial_view_over_southern_Bangladesh_reveals_extensive_flooding_as_a_result_of_Cyclone_Sidr.jpgTwentieth-century technofossils in inundated landfill deposits at East Tilbury on the River Thames estuary"While we often think of ecological damage as a modern problem our impacts date back millennia to the times in which humans lived as hunter-gatherers. Our history with wild animals has been a zero-sum game: either we hunted them to extinction, or we destroyed their habitats with agricultural land." – Hannah Ritchie for Our World in Data.[142]
