Where do materials in plants come from? (John Shanahan) USofA

Where do the materials in plants come from?

Mostly from carbon dioxide in the air and water.

John Shanahan October 7, 2018 The typical dry mass composition by percent in plants is:          

Hydrogen - 6 Carbon - 45 Oxygen - 45 Nitrogen - 1.5 Potassium - 1.0 Calcium - 0.5 Magnesium - 0.2 Phosphorous - 0.2 Sulfur - 0.1 Trace elements: Chlorine, Iron, Boron, Manganese, Zinc, Copper, Molybdenum

The carbon is sourced from CO2 in the air. The oxygen in sugars also comes from CO2.

All life in the oceans and on land comes from plants or other animals and has similar amounts of carbon, oxygen and hydrogen from carbon dioxide in the air and water.

All life needs carbon dioxide from the atmosphere.

2

Life without fossil fuels.

Carbon dioxide in the atmosphere makes all life possible and the world beautiful.

Does mankind need to control the amount of CO2 in the air? Can he?

3

Modern living is only possible by use of fossil fuels today and nuclear and fossil fuels tomorrow.

There is amazingly very little carbon dioxide in the atmosphere, about 0.04% or 400 parts per million. It is absolutely essential for life and all of nature’s beauty. Some in the media and alarmists say that humanity’s use of fossil fuels is causing catastrophic global warming, climate change, climate disruption, and sea level rise.

Energy from fossil fuels and nuclear is essential to have all the wonders of modern living, reducing human abuse of the environment and destruction of wildlife habitat.

Over the last two hundred years, fossil fuels have partially contributed to total increase of carbon dioxide in the atmosphere from 0.028% to 0.04%. Is that a problem?

Which is more important?

1) Stopping use of fossil fuels so that man-made atmospheric increase in carbon dioxide does not happen?

2) Continued use of fossil fuels to sustain the benefits of modern living and expand them to those who still don’t have them?

This 80 plus year old working cowboy, Doc Mishler, says that horses communicate better than some people.

Can people decide for themselves about the weather and climate rather than flatly accepting what some in the media, politicians and special agenda scientists tell them?

There is only a very small amount of carbon dioxide in the atmosphere. It is necessary for all of life. It has a tendency to become permanently sequestered through absorption in living things that form carbonate rocks. Once there, carbon stays there.
