The geometrical developing in poesy over the last century, when estimated, presents an ominous picture of massive, unsustainable growth and accompanying famines and wellness crises. Yet, to simply follow the current trend is naive, and informed estimates of population trends argon increasingly predicting a less disastrous future. The latest study shows an 85% chance that global population will peak before 2100, and predicts with 60% certainty that this peak will be less than 10 billion, compared with a population of 6 billion today. They even give an outside chance, 15%, that there will be fewer people life history at the end of the century than are alive now.

With these facts, there is no doubt in our minds that we are in for some trouble. Over the next 50 years, the United States alone faces some population problems. What we need to do is keep the growth rate at stage 4, meaning we need to have nascency and death rates low.
