Not only did the world not meet their estimates, I believe the UN was off by about 50 Million or 100% of its estimate. Which also means to me that sanity prevailed and we all looked at these estimates as what they really were: wild ass numbers pulled out of thin air and not estimates based on any factual scientific foundation.
