Earth's magnetic field
The magnetic field is also very important since some birds and insects use the field to navigate over long distances. They are able to do so by the magnetized iron crystals found in their skin for orientation. The most important function of Earth's magnetic field is protecting it's organisms. High energy protons are deflected along with electrons in the solar wind. If organisms have direct exposure to these particles it would be lethal.
