007skaty A luminous Renaissance fresco depicts figures rewriting the Earth's nitrogen cycle.
Nitrogen boost: Nearly half of the nitrogen atoms in your body's proteins were synthesized in a chemical factory using the Haber-Bosch process.
The proposed current geological epoch, in which human activity is the dominant influence on climate and the environment. Scientists trace the epoch's onset to 1950, when fossil fuel use and human population began growing exponentially.
How does the absorption of excess carbon dioxide from fossil fuels affect the chemistry of Earth's oceans?
Which greenhouse gas reached its highest atmospheric concentration in millions of years during the 21st century?
What term do scientists use to describe the dramatic, rapid surge in human activity and environmental impact that began around 1950?
What is the primary cause of the 'global species shuffle,' where plants and animals are introduced to entirely new continents?
What ecological term describes the current rapid loss of plant and animal species, often called the sixth mass extinction?
How has human activity affected the global rate of soil erosion and sediment transport compared to natural geological processes?
Which region of the Earth is warming at a rate two to three times faster than the global average, causing massive ice loss?
