Carbon Dioxide is Essential to Life

I learned the carbon cycle when I was in grade school in the early 50ty's. Animals breathe in oxygen and exhale carbon dioxide while plants do the opposite. God created this perfect balance of life in such a way that the composition of air stays relatively constant. Some scientists believe that the amount of carbon dioxide is increasing by a minuscule amount but this is based on unobservable estimates as to what the composition was 300 years ago before they even knew that carbon dioxide existed.

`

Carbon dioxide is believed to make up about .000387% of the air but this depends on where you are when you measure it.

While this essential gas may be considered a greenhouse gas it seems rather odd to consider it a pollutant. Carbon dioxide is toxic at concentrations over 5% But most things such as oxygen and even water are toxic in high enough doses. Carbon dioxide does not naturally occur in 5% concentrations that is well over 1000 times normal.

Most carbon dioxide is produced by natural events such as rotting vegetation, forest fires and volcanoes. Even if gases produced by burning fossil and renewable fuels increases by a significant enough amount that it tends to increase the concentration of CO2 plant life will naturally increase to reclaim the balance. Planting of trees by alarmist environmentalists will have no significant effect since nature will automatically do the job. Does the destruction of the rain forests increase carbon dioxide concentrations? Although deforestation seems undesirable most oxygen is produced by ocean algae which also eliminates most carbon dioxide. The amount of algae will increase in proportion to the available CO2.

Scientific studies show that higher concentrations of carbon dioxide should that happen would have the effect of increasing crop yields and increasing the efficiency of moisture. Would it increase Earths temperature significantly? We will know if it happens but it hasn't yet.
