The effects of the weakening Earth's magnetic field on humans (and today also on technology), as well as the natural disasters that occurred at least temporally in connection with it, decimated humanity and caused the extinction of animal species during past pole reversals, leading people to interpret these events as the end of the world or a transition to a new world. But the survivors had to repair or rebuild their social structures and supplies on the same planet Earth. Today, with our technology, we face more challenges in this situation, but also more opportunities to preserve the lives of as many people and as many habitats on Earth as possible. Among the challenges is the increased risk of major power outages, leading to the destruction of technical facilities and consequences for the refrigeration and transport of food, electronic money, lighting, heating, gas stations, government services, water supply, communications, electronic property registers, the internet, nuclear power plant cooling, and security. We are experiencing an increase in earthquakes and volcanic eruptions, but we do not know how far this will increase, particularly whether the reduction in sunlight caused by volcanic eruptions will lead to a new ice age. We will also need massive numbers of workers for disaster relief, especially to repeatedly repair the destruction caused by natural disasters. Mitigating the consequences of its ever-decreasing power, limiting the loss of human life, nature, and technology, and avoiding a technological regression to the Stone Age urgently requires international cooperation, especially in research, reforestation, and disaster preparedness.
