Wanted to share a comment I just posted on 
Rather than decreasing the exponential growth of human species, consider that the concept of a maximum number of humans on the planets may be a lie, or if you want to be generous, a misperception. In order to make natural resources seem scarce and therefore more valuable in the old monetary system, it was useful to spread this myth. There is plenty of room on Earth for many more people, including all of the resources we could ever need. There is lots of proof/evidence if you want to search this. But, it is much more convincing for you to find it through searching than for me to list the concepts. People are powerhouses of light. The more the better. Instead of planning for a reduction, let's plan how we can create GREAT experiences for the billions of people living on Earth in the future. That's something we can do.
