What is danger?

What Does danger Mean

From the Latin periculum , danger is a risk or the imminent contingency of something bad happening . It can be a physical threat, such as the collapse of a clearly deteriorated structure, or an abstract circumstance , which depends on the perception of each individual.

Let's see the term in context: "This avenue is a danger for pedestrians: this month alone there have been three deaths " , "We had to leave the house due to a danger of collapse" , "Having occasional sex without using a condom is a health hazard ” , “ Danger: slippery floor ” .
The danger, therefore, is associated with situations that have a damaging potential for the body , the environment or property. These circumstances are latent and are usually the first step towards the development of an emergency.

It is possible to distinguish between two very different types of danger:
* the latent danger is one that has potential for damage but has not yet produced it (such as a possible rock slide from a mountain that is in an area without people or homes);
* the potential danger , on the other hand, represents a threat capable of affecting people , their property or the environment, which requires a risk assessment and a possible evacuation (an example of this situation is an active volcano near from a town).
We speak of mitigated danger when the potential danger has been identified and measures have been taken to prevent an incident from occurring or to minimize its consequences (such as the construction of barricades to stop a flood of river waters).
With the advent of social networks and the lack of security measures to protect personal data, a deep fear of identity theft began to develop, of the distribution of private information such as photos and compromising documents; All this makes up one of the most discussed phenomena in recent times: the danger of social networks .
Danger of extinction
When it is probable that all the living members of a certain species , be it animal or plant, will disappear , it is considered to be in danger of extinction. Among the possible reasons are the direct predation of this species and the scarcity of a fundamental resource for its life, either due to modifications in its habitat due to natural disasters or progressive changes in the climate, or due to the destructive action of human beings.

To facilitate the monitoring of endangered species , conservation states were created, simple indicators of the probability that each one has of surviving in the short or medium term, taking into account issues such as the number of individuals and the way in which they which are distributed, their biological and natural history, and their predators, among others.
The International Union for Conservation of Nature ( IUCN ) produced the Red List , the most popular of documents that seek to classify the conservation status of different species. In it, there are two very specific categories under which the taxa whose continuity is at risk are located: endangered (whose official abbreviation is EN , since its English version is written endangered ) and critically endangered (which is abbreviated as CR , starting from critically endangered ). On the other hand is the vulnerable category, which indicates a less imminent threat.
For a species to be part of the endangered or critically endangered groups, its geographic distribution must have presented considerable fluctuations, whether it has been reduced or fragmented. In the 2009 edition of the Red List, the first category contains 2,448 species of animals and 2,280 species of plants; the second, 1665 and 1575, respectively.
