Pyrocene is a proposed term for a new geologic epoch or age characterized by the influence of human-caused fire activity on Earth. The concept focuses on the many ways humans have applied and removed fire from the Earth, including the burning of fossil fuels and the technologies that have enabled people to leverage their influence and become the dominant species on the planet.
The control of fire by early humans was a critical technology enabling the evolution of humans. Fire provided a source of warmth and lighting, protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food. These cultural advances allowed human geographic dispersal, cultural ...
The suppression of fire can lead to unforeseen changes in ecosystems that often adversely affect the plants, animals and humans that depend upon that habitat. Wildfires that deviate from a historical fire regime because of fire suppression are called "uncharacteristic fires".
Nearly 85% of U.S. wildfires are caused by humans, according to the U.S. Forest Service. Natural causes include lightning and volcanic activity. The Hawaiian Islands have six active volcanoes ...
He claims that even though mammals (such as humans) can have relatively long lifespans, we still operate under dinosaur-era restraints. Mammals may struggle to attain long life thanks to dinosaurs.
The hyperdisease hypothesis proposes that humans or animals traveling with them (e.g., chickens or domestic dogs) introduced one or more highly virulent diseases into vulnerable populations of native mammals, eventually causing extinctions. The extinction was biased toward larger-sized species because smaller species have greater resilience ...
Rainforest species didn't co-evolve with fire – and even a low intensity wildfire can kill half the trees. Amazon fires explained: what are they, why are they so damaging, and how can we stop ...
Fire frequency - this refers to the number of times fire occurs in a given area under a defined geologic time. The concept of fire frequency is often applied to local fire events. [25] Fire intensity - also known as fire severity or magnitude is the degree of fire or the magnitude of fire event. Fire intensity is categorized into low fire ...
