The correct answer is:

False

Explanation:

Some of the Positive feedback interactions in Earth’s systems are the result of human activities such as the increase in temperature because of higher concentration of carbon dioxide resulting in global warming is positive feedback result of human activities, but not all the interactions are because of the human activities such as it has been found that the tufts or plums of the methane gas bubbling out from the ocean on the surface, as Methane hydrates, melts and releases the methane. The methane increases the warming, which means that more methane is released. Now, this is also an example of positive feedback but this does not involve any kind of human interaction or human activity in it.
