The third decade of the 21st century has just begun and the environmental challenges ahead of us, reflected in the 2030 Agenda for Sustainable Development of the United Nations (UN), are numerous" (IBERDROLA, 2021): adaptation to climate change and, above all, its slowdown; rampant water and air pollution; the depletion of fossil fuel sources and the need to develop renewable energy sources; sustainable food models; biodiversity protection; urban development and sustainable mobility; water stress and the depletion of drinking water sources; the rampant increase in the world's population and waste management. These few words summarize the challenges facing humanity, but the magnificence and complexity of these challenges reach unsuspected limits, and the question is, are we still in time and do we have the capacity to face them? Humans, for the most part, are characterized by optimism. However, this feeling may have diminished in many, for example, as a result of the events that were triggered in the Chinese province of Hubei at the end of 2019, and that to this day keep humanity on edge. Why have we reached a situation like the current one? Whose fault is it? The two questions above can keep us debating for as long as we want, but is that what matters? For many years now - and with varying degrees of intensity - people, institutions, congregations and governments have been warning about the problems that are looming over us and that have brought planet Earth to the brink of irreversible collapse for the human species. But it is evident that this has not been enough to create the necessary awareness for everyone. If we do not manage to create a collective conscience in favor of the environment -which goes through an adequate popular and technical education- and we do not manage to put in the hands of each inhabitant of this planet a tool that allows them to be part of the solution, sooner rather than later we will have lost the battle.
