He environmental impact it is the effect caused by a human activity on the environment . The ecology , which studies the relationship between living beings and their environment, is responsible for measuring this impact and trying to minimize it.
For example: "The sinking of the oil tanker had an environmental impact of gigantic proportions for the Pacific Ocean ecosystem", “If the mining companies decide to settle in our city, they must demonstrate that the environmental impact of their projects will be reduced”, "The hypothetical environmental impact of the pastera has generated a confrontation between both governments".
The concept of environmental impact could be used to mention the consequences of a natural phenomenon (such as a tsunami or an earthquake), although such acceptance is rare. Typically, the notion is used to name the side effects that a certain economic exploitation implies on the nature . This means that a company It can create jobs and be very profitable from an economic point of view, but at the same time destroy the environment in the surrounding areas of your factory. The environmental impact, therefore, can have consequences on the population's health, air quality and landscape beauty.
In addition to all of the above, it is necessary to establish that, on a regular basis, a classification of the environmental impact is made based on the duration of its effect in a given place. Thus, taking that criterion, four different types of impact can be established:
• Persistent. In this group are those who have an influence on what would be long term.
• Temporary. As the name implies, it is the kind of environmental impact that does not really create large consequences, which means, therefore, that the environment can be recovered relatively quickly.
• Reversible. As a result of the aforementioned impact, the medium can recover from the damage suffered, in a more or less short time, but it may happen that it may not be completely as it was before the events took place.
• Irreversible. In this case, as the name implies, it is that environmental impact that is so important and serious that it completely prevents a scenario from recovering from the damage it has caused.
In order to be able to dictate both the type of impact it is and to be able to carry out the appropriate measures, based on that, it is important and fundamental to proceed to undertake its evaluation. In this task, experts will undertake from an initial analysis to a preliminary study through a concrete determination of it.
In this way, and after subsequent and thorough investigations, the impact can be determined as well as the measures that must necessarily be taken and it will also be decided whether the damage can be recovered in the short, medium or long term.
This is known as environmental impact assessment to the analysis carried out by a company or a government about the predictable consequences of an activity. Said analysis results in a environmental impact statement , which is the previous communication created under certain assumptions about the consequences predicted by the evaluation.
