Time seems to fly by. Earth is the sole habitat for human beings, and it is changing more and more. For some, it is changing, while some think it is wearing down and getting older. We have borne witness to stunning developments over the past 200 years in particular. However, improvements in production had societal repercussions following the advent of hydro and steam power and led to progress. The ensuing Third Industrial Revolution, billed as the digital transformation, quickly shifted routines and created a rather consumption-oriented society, so much so that we thought we owned everything. We have exploited natural resources for the sake of a comfortable life. In fact, we are not alone here. We coexist on Earth with 8.7 million other species.
On the other hand, improvements in living conditions have led to a boost in population, as well as in production. The U.N. reports that the global population, which was 1.5 billion in the early 20th century, totaled 3.7 billion in the 1970s following digital progress, particularly in computer and robot technologies. The global population now stands at 7.7 billion, with a more than twofold rise compared with the 1970s.
