Lets look at it in another way. It is true that the number of births per thousand people from year 2000 has reduced from 22 to 20 in year 2009, but on the other hand, the death rate has gone down from 9 to 8. The second billion was added in about 123 years and the population had grown to 2 billion in 1927. Rapid scientific progress is taking place in growing new organs and body parts from stem cell culture biotechnology which will lead to quantum jump in the length of life span of people.Planet Earth is facing a multitude of problems. But on the other hand food production may not be enough to feed the increased population and people may starve.4 billion by 2050.

　　The short and bitter truth is that the population problem is far bigger than one would like to face. We should look at it positively as a boon and gear up our efforts to manage the supply of food and water for the ever expanding future population. There is a limit to reduction births as every year about 40 million marriages take place and there are at least 200 million couples within the population who are potential baby makers.

　　. But the next phase of Mans efforts for increasing longevity has begun. We need to produce babies to keep our economies going. We need a growing population for sound financial health of any country. We must not disturb the delicate balance of the planet which may trigger drastic changes in rainfall and climate which in turn will affect the life on Earth. If we do not succeed, the quality of life would be compromised.

And at our individual and collective level, we must make every effort to heal the injury caused to planet Earth by Global warming and help her to cope with her inundation with us human beings. This resulted in more infants becoming adults and in more adults living a long life. The consumption of her resources by the small population did not challenge her in any way. He built dams to control floods, developed medical science and produced medicines to reduce infant and child mortality and to cure diseases. Population size will stabilize only when the number of births during the year equals the number of deaths in that year. Governments do not appear to have any effective legal measures to control population growth as enacting harsh laws is not politically possible. They are: water shortage, climate change, melting ice caps and global warming to name a few. Life expectancy thereby increased rapidly and has gone over 75 years in most of the countries of the World.

　　US Census estimates that the population of the World in 1 AD was about 170 million and after 1804 years it had grown to about 1 billion. Japan leads with a life expectancy of 82 years! That means the children born 82 years ago are still alive as grandparents!

　　World population, with its present growth rate, will more than double to reach 14 billion people by 2100. It seems now that life expectancy is beginning to level off. The next billion was added in only 32 years and the population had grown to 3 billion in 1959. Death rate includes infant and child deaths which are bound to go down rapidly thanks to Government efforts. At that level of population, the resources of the planet, particularly rain water and arable land area would have to be worked twice as efficiently.

　　There were several remarkable advances in medicine in the last century that has resulted in increasing the length of life from 30 years to 80 years. It is said that the generation which will live for 200 years is already born on tilting pad radial bearingthe planet. As the numbers of death reduce, the numbers of birth may not match their reduction.
