Environmentalism seems to be the fad of the moment; every day you hear or read about how human activity has changed Earth's environment: carbon emissions, global warming, etc. etc.

That got me thinking:
Perhaps one day Earth will be so industrialized, and skyscrapers will become so prevalent (with their accompanying lightning rods), that a potential difference no longer exists in Earth's atmosphere. Would its absence adversely affect life on Earth? Have any studies been conducted on this subject?

Does life on Earth require a potential difference in the atmosphere?

I'm not one to jump on the "Global Warming" by the hand of man, bandwagon.

The other planets in the solar system are exhibiting warming trends, so it's a solar cyclical phenomenon...and maybe we nudge it along a bit.

But, cutting down the forests, the concreting of huge landmasses and erecting artificial mountains that reach the sky has a impact on localized weather and flooding.

The Russians claim they can control the weather for hire.

I wonder.
