Question

Positive feedback interactions in Earth’s systems are always a result of human action. True of false?

Answer 1

False, but I have no way to explain it :(

Answer 2

false

Step-by-step explanation:

Positive feedback reinforces an action or response. For example, an increase of ice or snow in cold climates can encourage cooler temperatures and more ice and snow--a positive feedback. Negative feedback is usually more stabilizing and limits the deviation of the system.

This thing happens since ever, even where humans weren't on Earth.
