Humans shiver when it is very cold.

Explanation:

"Homeostasis" is the ability of the body to regulate itself in order to maintain a steady state. This includes mechanisms that allow automatic adjustment when the need for it arises. Covering ourselves with a blanket, taking a shower and turning on the air-conditioner are "not self-regulated" activities because they are done "intentionally" by the person. It is only "shivering" that shows the body's regulation of heat.

When the environment is cold, the skeletal muscles of the body respond by rapidly contracting and relaxing. This is what you call as "shivering." It produces heat through "respiration." Thus, it helps increase the body temperature.

it creates acid rain
