World poipulation

Sam D. sent me his thoughts on world population, thanks Sam:

World Population Crisis

There is little doubt that our world population is increasing rapidly. At the death of Christ, the world population is estimated to have been 300,000,000.In 1910, the world population was approximately 1,750,000,000. Now it is around 6,900,000,000. Whilst this brings numerous advantages, the disadvantages of this amazing increase outweigh the disadvantages. Population is hard to control in any respect. For most governments, population control is not an area of discussion. The people of most governments do not want to be told how many children they are permitted to have. Most governments have no means of controlling population anyway. In my opinion, almost all problems we face today would not exist if the world population was substantially smaller. I am not suggesting we pull out straws and kill six billion people, but merely expressing the opinion that if current increases continue, every problem we face will become worse.
Scientists at the University of Utah have announced that 1.2 million years ago, human would be classed by us today as an endangered species. There were so few of us that our development was much slower than today. However as living became easier with the introduction of agriculture and livestock, human numbers rapidly increased as threats that would be faced by most animals disappeared. This increases in numbers undoubtedly speeded up the course of the development of technology: the more people there are the greater the chance is that one will make a breakthrough.
However, population must have a limit. As population increases, problems emerge. Food shortages can lead to a decrease in the quality of life. Increased conflict can lead to strife. And, as we are seeing today, carbon emissions can rise to an uncontrollable level and change the earth’s climate. In short, overpopulation may mean that people start needing more than Earth can provide or we can make. There will no doubt be a shortage of land for farming, grazing and housing and a shortage of water for irrigation and drinking.
China and India are the countries with the largest populations. However, between the two, there is one huge difference. India’s population is spiraling out of control: it is due to overtake China in terms of population by 2040. This is due to China’s policy that every family with just one child will have free education and health care for that child (However, 10 women on average will still have 17 babies). This encourages people to have fewer children and this is most definitely needed: 20 in every 100 people are Chinese, that’s 1 in 5. India, on the other hand, is in a very different situation. On average, every ten women will have 28 children and there are no government attempts to control population and 17 in every 100 people are Indian. These figures contrast with the fact that less than 1 in every 100 people are from the UK*.
In conclusion, the world would be a much better place if populations decreased over the next few centuries. All of our problems would become less severe and possibly even disappear over time and the world would be a happier place with less to worry about.
