Biological pollution ( impacts or bio pollution) is the impact of humanity's actions on the quality of aquatic and terrestrial environment. Specifically, biological pollution is the introduction of non-indigenous and invasive species, [ 1] otherwise known as Invasive Alien Species (IAS). When the biological pollution is introduced to an aquatic ...
Biodiversity loss happens when plant or animal species disappear completely from Earth ( extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. [ 1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring ...
The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife . In ecology, overexploitation describes one of the five main activities threatening global biodiversity. [ 3] Ecologists use the term to describe populations that are harvested at an unsustainable ...
Genetic pollution is a term for uncontrolled [ 1][ 2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [ 3] but has come to be used in some broader ways. It is related to the population genetics concept of gene ...
Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas, genetically modified foods and global warming. The UN system has adopted international ...
v. t. e. Ecology (from Ancient Greek οἶκος (oîkos) 'house' and -λογία ( -logía) 'study of') [A] is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels.
Environmental science is an interdisciplinary academic field that integrates physics, biology, meteorology, mathematics and geography (including ecology, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems.
