1. Introduction

The U.N. has revealed the change in those living in urban areas, from 1950 to 2020. more than 56% of the global population now lives in cities. The biggest change has been in Latin America and the Caribbean, with 81.2% of the population living in urban areas, up from 41.3% in 1950

Many of these people will never have the opportunity to experience the wonderful glow of the stars in their city. I remember the summer nights in Moraira, in my Valencian land, while we lay around the pool to look at the sky, we stared at the stars until well into the morning it was and continues to be a wonderful show, I recommend it, not only to observe the greatness of the universe, but to realize that we must conserve and value it, it is a task for everyone. Today in very few cities a person can have the privilege of enjoying this show.

Light pollution is a worrying issue, it generates high energy costs, problems for human health and for nature, obviously it is not a problem that we can solve in 24 hours, but we must all take small steps to reduce this pollution little by little.

Just over a century ago our ancestors could still look up in some big cities and see the starry sky, now millions of children around the world will never experience the Milky Way where they live. The increasing and widespread use of artificial light at night is negatively affecting our environment, our safety, our energy consumption and our health and, of course, our view of the universe.


2. What is Light Pollution?


The excessive or inappropriate use of artificial light, known as light pollution, can have serious environmental consequences for humans, wildlife, and our climate..

The development and advancement of our civilization have caused light pollution. It can be due to both indoor and outdoor lighting in parking lots, advertising, offices, factories, and street lighting. The problem is most acute in highly industrialized and densely populated areas of North America, Europe, and Asia.

We can change this trend by developing habits about lighting control and this requires lights to be used more efficiently, without waste and without unwanted lighting.

A light that helps us to perform our task correctly but if it bothers our neighbor, this light becomes contaminated, since it should only illuminate what we are interested in and not harm other people. Therefore, lighting control is necessary and appropriate measures must be taken for each area to be illuminated.
