Can't see the tress because there's no forest

Continued from Part 2.


(The start... Part 1)



What the varve data analysis demonstrates is that climate changes. This is not a result of human intervention through CO2 emissions, rather the correlations to CO2 could be be demonstrated to be related to temperature. That is, if the other way around.


Deforestation is also related to CO2. Mature trees do not make a great amount of O2 as people are taught in school. This occurs as the grow and store carbon. When mature the balance forms an equilibrium. When they are removed, the balance is disturbed.


In addition to deforestation around the globe, the most significant sources of forest around the world aredisappearing in every country where they are located.

The problems with deforestation

  • Soil erosion With the loss of a protective cover of vegetation more soil is lost.
  • Silting of water courses, lakes and dams This occurs as a result of soil erosion.
  • Extinction of species which depend on the forest for survival. Forests contain more than half of all species on our planet - as the habitat of these species is destroyed, "Biodiversity" declines.
  • Desertification The causes of desertification are complex, but deforestation is one of the contributing factors to desertification. Less trees equals a dryer climate.
  • Flooding
Cutting down trees is not the issue as is commonly stated either. The issue is not replacing what we have removed. This is a problem with poor governance and stewardship. Deforestation is an issue that has an impact now. It is something we can do now. Debating CO2 is a way of avoiding the real issues.
