Meaning of Environmental Crisis (What is it, Concept and Definition)

What is an environmental crisis:

An environmental or ecological crisis occurs when the environmental environment where a species or population lives undergoes changes that threaten its continuity.

The changes disrupt the ecological balance , since an ecosystem functions as a whole interconnected by multiple interdependence relationships, and the variation of some of its elements produces imbalances that affect different degrees, and directly or indirectly, the way of life of the organisms (biotic factor) that cohabit there, as well as the natural processes of non-living physical elements (abiotic factor), such as water, temperature, soils, air, sunlight , etc.

Among the abiotic factors , phenomena determined by climate change, such as the variation of temperatures, the amount of rainfall or atmospheric humidity, as well as others fortuitous events, like a volca eruption Unique or the fall of a meteorite can severely affect environmental conditions.

On the other hand, biotic factors that compromise the ecological balance of a habitat they are the migration, disappearance or extinction of a species; the appearance or invasion of an exotic species in an ecosystem that is strange to him, as well as the overpopulation or intense depredation of a particular species.

On the other hand, the so-called anthropic factor , that is to say, the intervention of the human being modifying the natural environment, destroying soils, diverting the river bed, destroying virgin forests, depleting or degrading natural resources, consuming energy indiscriminately, introducing foreign species into habitats, etc., produces a strong environmental impact whose consequences are conducive to ecological crises.

See also Crisis.

environmental crises are characterized by an accelerated loss of biodiversity as a consequence of the mass extinction of species, a widespread destruction of habitats, and a negative impact on the conditions for the regeneration of natural resources.That is why, to avoid environmental crises, they govern them the world must stimulate sustainable development policies.

Global environmental crisis

Like global environmental crisis or global ecological crisis is called the one that generally affects the living conditions in the ecosystems that make up the planet.

The environmental crises we suffer Nowadays on a global scale they can be recognized in the extinction of thousands of species each year, the depletion and degradation of natural resources, global warming, the destruction of the ozone layer, the increase in rainfall, hurricanes and cyclones in some regions, as well as the exacerbation of droughts in others.All this without counting environmental accidents due to direct human negligence, such as oil spills in the waters of the Gulf of Mexico or accidents at the Chernobyl or Fukushima nuclear plants.

In this sense, today being hum Anus has a more complete understanding of the effects and consequences of his actions and the way in which they directly or indirectly, mediate or immediately affect the rest of the species and life forms with which he cohabits on Earth, and counts with the tools to avoid global environmental crises, but it must deprive the political will of the world's rulers and the conscience of its inhabitants to be able to implement them.
