climate-change happened for millions of years, some periods in the past had a higher content of carbondioxide CO_2 and all worked fine. If anyone wants to plant this tree, one should follow several rules:

• 11 levels of plants at different hight.
• 40 or more different plants/trees/bushes which can
  live and grow together harmoniously.
  A good example are the videos of theparenttreefarm.de , Andreas Pfeifer , who does this since 2007 .
