In the case of darker parts of the internet, the algorithms produce a destructive positive feedback effect.

This was the least important factor, though this feedback effect often led to an undesirable thrust oscillation called pogo.

Associated changes in surface albedo and ocean-atmosphere heat and gas exchange accelerate global warming, having a positive feedback effect.

What started off as a financial crisis for the banking system would become one where the economic feedback effects were dangerous and uncontrollable.

Road construction has the largest feedback effect, because it interacts withand leads tothe establishment of new settlements and more people, which causes a growth in wood (logging) and food markets.
