A frontier ethic assumes that the earth has an unlimited supply of resources. It is the notion of disregarding the Earth for the benefit or gain of man. If resources run out in one area, more can be found elsewhere or alternatively human ingenuity will find substitutes. This attitude sees humans as masters who manage the planet. It is completely Anthropocentric.

Answer :
Explanation :

Fermentation is the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.   The two most common types of fermentation are (1) alcoholic fermentation (and)  (2) lactic acid fermentation.   (1) Alcoholic fermentation : the type of fermentation in which ethyl alcohol is the main end product .This is very common in yeast (unicellular fungus) and also seen in some bacteria. Yeast cells release enzymes called zymase complex which bring about the fermentation. The reactions are similar to anaerobic respiration.   (2) Lactic acid fermentation : The type of fermentation in which lactic acid is the end product. It is carried out by some bacteria (e.g. lactic acid bacteria), and also by animals (muscle glycolysis in animals, under oxygen deficiency, results in the formation of lactic acid this is whay we experience in muscle cramps, or "Charley horse").
