Explanation:
option 2) voltaic cells only
<em><u>I </u></em><em><u>guess </u></em><em><u>so </u></em><em><u>this </u></em><em><u>is</u></em><em><u> </u></em><em><u>the </u></em><em><u>answer</u></em><em><u> </u></em><em><u>or </u></em><em><u>not </u></em>
That answer is what characteristic you have.
One of the oxygen atoms in the anion O3− is hypervalent and the formal charge on this oxygen atom is -1.
Ozone is a triatomic molecule. The anion formed from ozone is called the ozonide anion. This anion is also triatomic. The resonance structures of the ozonide anion are shown in the image attached to this answer.
We can see that one of the oxygen atoms in the ozonide ion is hypervalent because it contains ten instead of eight electrons. This hypervalent oxygen atom has a formal charge of -1 while the two other oxygen atoms has a formal charge of zero.

Deforestation....trees release water vapour..with the trees being cut down less water vapour is being released..
consuming the water.... we use up water for drinking and for our homes etc...
hope this helps!
