What goes in cellular respiration and what comes out of cellular respiration?

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Humans destroy an organism's environment, which then takes away the place they live. Once organisms get used to one type of lifestyle, it is very hard for  them to leave that lifestyle. Once we destroy their lifestyle they do not know what to do, so they die.
