What are the global challenges?
The human is today a highly invasive species on the planet. We are everywhere, consuming the earth's readily available resources, and our perceived "success" kills and destroys the conditions of life.
There are currently 50-100 global challenges, depending on how you define them. Every global challenge within the economics, technology, geopolitics, environment and social area, has the potential to create domino effects that, in the worst case, cause our civilization to collapse. Mankind's greatest challenge is thus not, for example, climate change but the total risk of all global challenges.
