No. Damage from extracting 'large volumes' is insignificant. (waste is another issue)

You are completely off scale. The oceans contain 1.34e+21 L. Humanity uses 1.38e+17J annually. If we take ~10J to move 1Kg 1m up. That means if we spend all our energy on moving sea water, we can move 0.00001% of the ocean up by 1 meter per year.

Any novel ecosystem is close to shore, from those ecosystems most are already damaged by other means.
