It would seem that in the era of modern digital technologies, satellites and other benefits of civilization, we can explore every centimeter, but this is far from the case. Yes, you can look through a satellite at any territory on the planet, but exploring is not so easy. For example, the Amazon forests or the Siberian taiga are poorly explored. The bottom of the world’s oceans, especially deep-water depressions, has been studied very poorly. Yes, and on the continents, you can find many places, just their territory is relatively small, but it is difficult to explore them because of the difficult conditions.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
