These devices are not transformers, but toroid hall effect sensors. That is how they can sense DC.
Unicron was never really in Transformers: Cybertron but, Megtron (Galvatron) had the armor of Unicron and the black hole that the hole story was based off of was the effect of what happened when the Transformers destroyed Unicron.

Helicopters do not affect the environment.
no
floods effect the environment by over increasing the level of water tables which is dangerous

There is no effect. The common grounding is just what it states. Common potential of zero is the result when transformers are grounded. There is no current feeding between the transformers because their "hot" ends of the coils are isolated from one another.
Humans interact with the environment creating great change. The largest effect of how humans interact with this environment is the destruction of rainforests.
