Resumen
La humanidad
Área de la Ciencia:
- Ciencias del medio ambiente
- Ciencias de la Tierra
- Antropología
Sus antecedentes:
- La humanidad es una fuerza dominante que da forma a la geología y los ecosistemas de la Tierra.
- Una cuestión emergente es la comparación de la producción de material humano con la biomasa natural.
Objetivo del estudio:
- Para cuantificar la masa total de materiales hechos por el hombre (masa antropogénica).
- Para comparar la masa antropogénica con la biomasa viva global.
- Para caracterizar la empresa humana en el contexto del Antropoceno.
Principales métodos:
- Cuantificación de la masa hecha por el hombre.
- La comparación de la masa antropogénica con las estimaciones de la biomasa viva global (aprox. 1.1 teratoneladas) en el mismo período.
Principales resultados:
- En 2020 (±6 años), la masa antropogénica alcanzó un punto de cruce con la biomasa viva global.
- La masa antropogénica se ha duplicado aproximadamente cada 20 años.
- Cada persona produce una masa antropogénica semanal que excede su peso corporal.
Conclusiones:
- La Tierra está en un punto de cruce donde la masa hecha por el hombre es igual a la biomasa viva global.
- Esto pone de relieve el impacto material significativo de la empresa humana.
- Proporciona una caracterización basada en la masa de la época del Antropoceno.

Threats to Biodiversity
25.8K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Population Growth
26.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

The Carbon Cycle
42.5K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

What are Biogeochemical Cycles?
38.7K
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.

Habitat Fragmentation
20.4K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
