Conversation so far:
what is meant by a negative feedback system
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output.
how is the negative system different from positive feedback
The positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative system feedback generally promotes stability.
how are negative feedback systems important to real life
Negative feedback loops also play an integral role in maintaining the atmospheric balance in various systems on Earth.

Question: can you give me an example
Self-contained rewrite: can you give me an example iof negative feedback on earth's atmosphere
