Perhaps one of the most used and enjoyed natural spaces by human beings, the beach is considered a geographical accident that always takes place immediately after a body of water, establishing itself as a limit to it. The beaches are unstable as their dimension varies according to the constant movement of the water, and this is especially clear in the beaches formed next to the sea or the ocean that, unlike the waters of lakes or lagoons, are in permanent movement.
In general terms, it could be said that a beach is formed through the action of water. It moves and transports different types of sediments that are being placed in the place, thus forming areas of less wateriness and greater terrestrial space. These sediments, however, are not permanent and that is why, depending on the tide, the size or extension of a beach can vary completely. In any case, the change is never total since the contribution of sediments is permanent and a stable surface is formed on which different activities can be carried out.
The beach is, without a doubt, a habitat for many aquatic species that can live in both aquatic and terrestrial spaces. At the same time, in many cases the beaches have significant vegetation all around them, which always has to do with the climate and the type of temperature that occurs in each specific region. Obviously, this is so when we do not talk about the intervention of the human being.
As for a place of recreation, the beach is currently one of the most popular options for tourism since it allows us to come into contact with the sea or the appropriate watercourse, carry out relaxation and rest activities and be exposed to the open air. A large number of beaches around the world are some of the most important and visited tourist destinations, growing more and more and offering the public an incredible variety of options to enjoy the experience. In many cases, some specialists in tourism have been able to take advantage of the commercial benefits that a beach provides and as a consequence of this situation, artificial beaches have been created that have little or nothing to do with nature but are definitely a tourist attraction. further.
The presence of human beings undoubtedly causes the natural space of the beach to change profoundly. This not only has to do with pollution, but also with the erosion and disturbance that can be generated by having large numbers of people on the move. As a consequence of this, many beach areas have completely changed their natural structure and have become unsuitable for human presence.
