What are the historical trends in population growth?
The world population is at 7 billion in 2012 and is growing by 80 million each year. The forecast is that in 2030, the population will reach 8-9 billion. The population has been growing gradually until 1900 when the population suddenly multiplied rapidly. In 1800 in took 130 years for the population to double, however a hundred years later, it was only 65 years to double the population and this number has been decreasing ever since. It is expected that third world countries will triple the population within 50 years. From the income/birth and death rate per 1000people, we can see that as the income raises, the gap between birth rate and death rate increases. The death rate decreases as income increases but so does the birth rate, however the death rate decreases by a higher margin. Half the world’s population growth happens in six countries: India, China, Pakistan, Nigeria, Bangladesh, Indonesia. More economically develop countries often find out that between 1800 and 1900, the death rate is almost equal to birth rate; however in less developed countries, there were 3 times more births than deaths by 1900.
What impact does population growth have on resources and international conflict? The problem with overpopulation is that there are not enough resources spread across the world, some parts of the world has too much and some do not have at all. This is mainly the problem because resources are scarce in places where the birth rates are much higher than death rates which mean the problem is increasing in importance over time. However, we must understand that overpopulation is not the sole reason places with high population growth suffer from hunger. The main reasons for this are poverty and politics, governments that are not able to provide for their people and no monetary resources to purchase food. The world
