Facts and insights about how the many systems of the Earth connect and interact,
about the forces that trigger changes in their inner workings and in the climate,
and what we as inhabitants of the Earth can do to ensure that this planet will continue to enable us to have a life.

THE FUNDAMENTALS
THE INSIGHTS

The Earth is approximately 4.5 billion years old. Throughout its life so far, it has gone through significant changes caused by inner and outer events. Just in the last 500 million years, there have been five mass extinctions of various species of life, caused by natural events such as volcanic activity or asteroid impacts. On the other hand, modern humans (homo sapiens) have existed only in a tiny fraction of the most recent segment (about the last 0.01 percent) of Earth’s life, but human activity already impacts the makeup and health of this anciently powerful body of enormous mass.
In our current days, human activity has reached such scale that has transformative impact on this same powerful enormous body of Earth. These impacts are measurable, and some of them are tangibly noticeable even within one human lifetime. This means, knowledge about the Earth and its inner workings is of utmost importance—not only for scientists, but also (to some extent) for people in the general population; because that’s the only way humans (the only sapient species with complex reasoning) can understand the impacts of their deeds and everyday habits, and make sound decisions for both their immediate lives and for lives in the future.
