Sustainability is a social goal for people to co-exist on Earth over a long time. Definitions of this term are disputed and have varied with literature, context, and time. [2] [1] Sustainability usually has three dimensions (or pillars): environmental, economic, and social. [1]
In statistics and applications of statistics, normalization can have a range of meanings. [1] In the simplest cases, normalization of ratings means adjusting values measured on different scales to a notionally common scale, often prior to averaging. In more complicated cases, normalization may refer to more sophisticated adjustments where the ...
RGR is a concept relevant in cases where the increase in a state variable over time is proportional to the value of that state variable at the beginning of a time period. In terms of differential equations, if is the current size, and its growth rate, then relative growth rate is. If the RGR is constant, i.e., a solution to this equation is.
Natality in population ecology is the scientific term for birth rate. Along with mortality rate, natality rate is used to calculate the dynamics of a population. They are the key factors in determining whether a population is increasing, decreasing or staying the same in size. Natality is the greatest influence on a population's increase.
Net migration rates per 1,000 people. The net migration rate is the difference between the number of immigrants (people coming into an area) and the number of emigrants (people leaving an area) divided by the population. [1] When the number of immigrants is larger than the number of emigrants, a positive net migration rate occurs.
An economy that would be able to sustain economic growth while reducing the amount of resources such as water or fossil fuels used and delink environmental deterioration at the same time would be said to be decoupled. [2] Environmental pressure is often measured using emissions of pollutants, and decoupling is often measured by the emission ...
A 2021 report in Frontiers in Conservation Science proposed that population size and growth are significant factors in biodiversity loss, soil degradation and pollution. Some scientists and environmentalists, including Pentti Linkola, Jared Diamond and E. O. Wilson, posit that human population growth is devastating to biodiversity.
Paleontology ( / ˌpeɪliɒnˈtɒlədʒi, ˌpæli -, - ən -/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -ən- ), also spelled palaeontology [a] or palæontology, is the scientific study of life that existed prior to the start of the Holocene epoch (roughly 11,700 years before present). [citation needed] It includes the study of fossils to classify ...
