Similar to sustainability initiatives on Earth, space sustainability seeks to use the environment of space to meet the current needs of society without compromising the needs of future generations. [ 4 ] [ 5 ] [ 6 ] It usually focuses on space closest to Earth, Low Earth Orbit (LEO), since this environment is the one most used and therefore ...
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.
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point.
While the landscape is still almost entirely snow, ice and rock, this small, green area has grown dramatically since the mid 1980s, said Thomas Roland, a study author and environmental scientist ...
