Question

Explain what kind of feedback is operating in this example: more and more people around the world are using more and more electricity, mostly made by more and more coal-fired electric power generation facilities burning more and more coal to run more and more air conditioners in larger and larger houses, causing more and more CO2 emissions which are trapping more and more heat in the atmosphere causing the Earth to get hotter and hotter, and more humid. How could we stop this feedback loop?

Answer 1

The basic feedback applied in this mechanism is the continuous utilization of non-renewable resources. These are extracted from earth and are converted into various forms and are used in accordance . This forms a loop when previous ones are exhausted and the overgrowing population demands more resources. Hence the loop continues.

For this loop to stop , there is are two alternatives. First one is to use them continually till they are completely exhausted. But this is a destructive technique that will lead to a dark future.

Another method is to use the resources in a controlled and coordinated method and finding more new renewable resources like wind energy, solar energy which will lessen, or could end the previous feedback mechanism.
