world population

The number of people sharing Earth's resources is growing by the minute. Scientists predict that by 2050 there will be more than 9 billion people in the world. This is a huge number of people, will Earth be able to support this many people in the human population.
By 2050, I am assuming that the Earth will not be able to support everybody and food will be much more unhealthy. The food, it will not be as healthy, and the life expectancy will not be as long as it is now. You would have to factor in how land residential will waste, and how much farmers will use to grow crops and how much ranchers will use to raise livestock.
In nations with good health care and reliable food supplies, people are living longer lives. In the past half- century world wide average life expectancy has increased from 46 years to 68 years old. Also, infant mortality rates have fallen in many countries, which is a horrible thought that babies across the world are dying because of bad health. With all of the countries having a positive population growth, if the world doesn't end in 2012 the population will eventually be so crowded that trees can not produce enough oxygen and natural selection will then occur. Societies gong though these changes are generally those that have undergone the shift from rural life to urban life and industrialization, and that have generated personal wealth for their citizens.
Ignoring these difficulties, the population growth of developing nations as a whole surpasses population grown in developed nations. This trend has been currently rising for many of years and has not yet peeked yet and wont peek for many years to come. Life expectancy can be depended on wealth also, not just what is available. Children now are much more healthy, rather than 50 years ago when they were bathing in muddy water. Their parents are full of money and provide better lives for the young ones.
By 2050, its predicted that there will be 9 billion people in the world, that is a very large number of people. It will more than likely very hard to support this large pass of world population.
