You know how it is sometimes fun to sit around and Google things that just pop into your mind? Well, I was doing that tonight while pondering the world around us. I was thinking about trees and plants, and how they figure into our environment. The process I looked up was photosynthesis.
We would not have oxygen to breathe if it were not for carbon dioxide (CO2) and plant life.
6H2O + 6CO2 ———-> C6H12O6+ 6O
Six molecules of water plus six molecules of CO2 makes one sugar molecule and six oxygen molecules.
This is what happens. Plants get their water from the ground through the root system, and they suck in carbon dioxide gas (CO2) from the atmosphere. That’s when the fun starts.
Sunlight is the energy that drives the whole process. When sunlight strikes a leaf of a plant, energy is absorbed. Some sunlight causes heat, and the rest causes chemical reactions between the CO2 and other stuff in the plants. Oxygen is split from the carbon dioxide and water (H2O), and sugar and enzymes result growing the plant.
If it were not for CO2 we would not have trees, plant life, food, or oxygen. It gets that simple.
Global warming is blamed on CO2. There is only a small bit of truth to this in that CO2 is a greenhouse gas, and greenhouse gases cause the earth to keep warm enough to support life, but not too warm. CO2 is not the driving gas in the process. The real driver is water vapor, by far the strongest greenhouse gas in the atmosphere.
Photosynthesis is yet another process that can be called a Goldilocks process. It takes in carbon dioxide (CO2), and produces food and oxygen, all necessary for life.
Our earth is just far enough from the sun to keep it warm within a livable range. We live on a water planet where the climate is pretty much automatically maintained by clouds, water vapor, water vaporization and condensation, and the associated heat engines.
When things heat up, clouds form, rain happens, and things cool down. That’s one of the mechanism that keeps the world from getting too hot. Greenhouse gases keep the world from getting too cold for life.
Food and water are plentiful almost everywhere because of the natural processes.
What more can one ask? We do live in a Goldilocks world. It is almost like things were planned that way. Our Goldilocks world is just right.
Note: Yes, I noticed in the chemical equation that the Oxygen molecules did not balance. I did a cut and paste from some web page, and am now paying for my own inattention. I think that the six oxygen molecules should be molecules made up of 2 oxygen molecules. Oxygen does that, you know. I just don’t know how to do a subscript in WordPress.
