Estimates of the rate of deterioration caused by human stresses placed on the Earth. Some of these accelerate in their deterioration as the supply becomes limited because greater demands are being placed upon a smaller and dwindling supply. It is difficult to get quick answers general estimates but below are some numbered links to web sites that explore the issues

  1. Loss of topsoil 1234567
  2. Desertification 1234567
  3. Deforestation 1234567
  4. Toxic poisoning of drinking water 123456 – 7 –
  5. Oceanic pollution 12345 – 6 – 7 –
  6. Shrinking wetlands 123 – 4 – 5 – 6 – 7 –

This blog isn’t finished. The intent is to create links to each of the basic items, so you can check into the source materials; then there will be an estimate as to how serious this risk factor is and how likely it is to interact in a synergistic way with the other factors. Mineral exhaustion and pollution blowback appear likely to be the real terminators of our present good times. They will impact our society long before the inevitable global sea level rise will become an unavoidable problem.
