The Oscilloscope reading on the right is grounded and the reading on the left is not grounded.
The electrical readings below show what happens after someone touches the plant's leaf. The grounded plant is barely effected by the stimulus, while the disconnected plant is significantly increased.
The electrical fields on Earth affect the atmosphere and environment around our planet. All organisms have attuned their biology to the Earth’s direct current (DC) electrical field that has a frequency of 7.5 - 8.0Hz, otherwise known as the Schumann Resonance.( Adkins, Charles. ‘Barefoot Technology.’ July, 2010.) <http://thebiotitan.blogspot.com/2010/07/barefoot-technology-caveman-lesson-to.html>
The power distribution systems around the world use 50 - 60 Hz alternating current (AC). Alternating current is foreign to all organisms’ biology and is being researched as a factor in a variety of human stress-related responses and other biological complications. (Ober, Clinton.
