We have done very well as a species. We took a planet with a carrying capacity of less than 1 billion people. As result of our work and design the planet now supports more than 9 billion and growing. If that were not enough, all of our metrics are improving: fresh clean water, education, safety and security and on and on.
We need more people; we do a good job. God asked us to steward His world, and we have done an outstanding job.
