5.2 - Planetary Dangers of Development

If one takes these events or their causes as a basis and then asks oneself further which cosmic and planetary sources of danger come into consideration, then a whole list of possibilities results:

• Cosmic Rays
• Gamma Flash
• Supernova
• Solar Eruption
• Asteroid Impact
• Cometary Impact
• Ghost Planets, vagabonding Stars
• Ice Planet (Snowball Earth)
• Climate Change
• Atmospheric Change
• Change in Sea Level
• Volcanism
• Supervolcano

These are a total of 13 possible planetary threats that have the potential to destroy the entire biosphere of the Earth.

More detailed explanations and pictures of the individual planetary sources of danger can be found in the book
