Hello llockard,
The answer is <em>pe</em><em>t</em><em>roleum.</em><em>.</em><em>.</em><em> </em>It is because trees, water, plants, natural gas can take only 2 - 31 years to be made again... BUT, in case of petroleum, it takes nearly 100000 years, which is impossible for any human to live that much years... So, use petroleum carefully....

Ghrelin is a hunger-stimulating hormone which is secreted by specialized cells in the stomach.
Ghrelin is a hormone made in the intestine. It is often called the "hunger hormone" and is sometimes called lenomorelin.
It reaches the brain through the bloodstream and tells the brain to feel hungry and start looking for food.
It's main function is to increase appetite. Eat more food, take in more calories and store fat.
In addition, it affects the sleep-wake cycle, reward-seeking behavior, taste sensation, and carbohydrate metabolism.
This hormone is made in the stomach and is secreted when the stomach is empty. It enters the bloodstream and affects a part of the brain called the hypothalamus, helping regulate hormones and appetite. Lower levels make you feel fuller and easier to cut calories.
