Population pressure, a term summarizing the stress brought about by an excessive population density and its consequences, is used both in conjunction with human overpopulation and with other animal populations that suffer from too many individuals per area (or volume in the case of aquatic organisms).
Population geographyis the study of the distribution, composition, migration, and growth of human populations in relation to the geographic characteristics of specific area. It focuses on how populations are distributed across space, the factors influencing these distributions, and the implications for resources, environment, and societal ...
Environmental issues in New York City are affected by the city's size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River. New York's population density has environmental pros and cons. It facilitates the highest mass transit use in the United States, but also concentrates pollution.
Landscape of United Arab Emirates Environmental issues in the United Arab Emirates (UAE) are caused by the exploitation of natural resources, rapid population growth, and high energy demand. The continuing temperature rise caused by global warming contributes to UAE's water scarcity, drought, rising sea level, and aridity. The UAE has a hot desert climate, which is very vulnerable to the ...
Pollution by heavy metals decreases the soil organic matter composition resulting in a decline in soil nutrients which then leads to a decline in the growth of plants or even death. [198] Besides creating environmental damage, the contamination resulting from leakage of chemicals also affect the health of the local population. [199]
Population and Environment is a quarterly peer-reviewed academic journal covering research on the reciprocal links between population, natural resources, and the natural environment. The journal was established in 1978 as the Journal of Population, obtaining its current title in 1980. [1] The editor-in-chief is Brian Thiede (Penn State University).
Since technology can affect environmental impact in many different ways, the unit for T is often tailored for the situation to which I=PAT is being applied. For example, for a situation where the human impact on climate change is being measured, an appropriate unit for T might be greenhouse gas emissions per unit of GDP.
In a population, carrying capacity is known as the maximum population size of the species that the environment can sustain, which is determined by resources available. In many classic population models, r is represented as the intrinsic growth rate, where K is the carrying capacity, and N0 is the initial population size.
