Did you know The Earth Was Perfectly Designed To Clean Itself?

Apparently, Rev. Bill McGinnis does.

Inspired by bird poop on his car, he states the earth was divinely/intelligently designed to clean itself up. He notes how different species eat dead bodies & decaying matter & that "The water in the rain tends to dissolve almost everything that needs to be cleaned up...The tapping action of the individual raindrops hastens and promotes the clean-up process."

He then goes on to describe the water cycle and the fact that EVOLUTION could not have designed the WEATHER (?) to be as perfect as it is. "Never is ten zillion years could all of these things come together so perfectly by chance to accomplish a needed objective like cleaning up."

Despite human being destroying the earth's balance (water pollution, acid rain, species destruction, dams). "Atheist" fabrication of evolution fails in the light of the fact that EARTH has no genes to randomly mutate.

Therefore we return to the core truth: "In the beginning God created the heaven and the earth."

A helium-filled balloon at 1.00 atm pressure has a volume of 1.350 L?

It is placed in a freezer and its volume decreases, stopping at 0.980 L.
(Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.)
Calculate deltaE for the gas in the balloon.

What is the voltage of eletricity when it comes out of an eletric plant?

I heard that electricity comes out of a hidroplant with a much higher voltage than what we use at home. How do they lower the voltage? Is there wasted eletricity (energy) in the process?

Thanks for helping me understand this.
