Cyles and Feedback Loops I

Cycles and Feedback Loops

Some Feedback Loops

  • Gaia as a Feedback Loop

  • The Earth itself is a material cycle

  • Over time the earth acheives a balance which is disrupted by random catastrophe

    Exponential use of resources represents a "short-term" random catastrophe for ecosystems as this disrupts the natural resource cycles. The system can not recover on such a short timescale.
