Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [147] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.
Decline in average human body temperature since the 19th century: Medical data suggests that the average body temperature has declined 0.6 °C since the 19th century. The cause is unclear although it has been suggested that it has some relation with reduced inflammation from reduced exposure to microorganisms.
Human biology is an interdisciplinary area of academic study that examines humans through the influences and interplay of many diverse fields such as genetics, evolution, physiology, anatomy, epidemiology, anthropology, ecology, nutrition, population genetics, and sociocultural influences.
Synthetic biology includes the broad redefinition and expansion of biotechnology, with the ultimate goals of being able to design and build engineered biological systems that process information, manipulate chemicals, fabricate materials and structures, produce energy, provide food, and maintain and enhance human health and the environment.
Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Human is a loanword of Middle English from Old French humain, ultimately from Latin hūmānus, the adjectival form of homō ('man' – in the sense of humanity). [9] The native English term man can refer to the species generally (a synonym for humanity) as well as to human males. It may also refer to individuals of either sex. [10]
An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives.
