The Growing Human Population The human population has been on the rise for the last century. The growth has been attributed to fertility and economic changes. Research shows that, for the last four decades in 20th century, population has doubled from 2.5 billion to 5 billion, and by the end of 20th century, the population had surpassed 6 billion (Hopkins).
The human population has been growing for the last decades at the rate of 1.5% showing that the population will have reached 12 billion by the end of 21st century. Population has been increasing by a quarter of a million each year. This rate of increase has had a severe impact on the environment. The world most populated country is China with the population of 1.2 billion people. The population of China is expected to double in the next 60 years. This will happen despite China’s government enacting policies of one child per couple. Additionally, the population growth in USA is growing at the rate of 1%, with current population of 270 million, it is estimated that the population will be double in the next 70 years (Pimental 1)
Increasing population is attributed to fertility rate, this is evident when developed and developing countries populations are compared. Analysis of developed countries such as in Europe and USA shows that they have less population growth. The study of population growth in the developing countries shows that their population is increasing at alarming rate. This could be attributed to the fact that couples in developed countries are well aware of the cost of large families. Approximately 2 billion of the world populations are malnourished; this number is expected to double in the future. Populous countries like India have the high number of poor people, to add this, food production is a problem, and these are just some of the negative aspects of large populations.

Now whether this growth will continue consistently depends on ecological aspects.

... 07 October Human population: A population pyramid is a highly effective tool which holds great potential to help experts examine and record population statistics very closely. It helps to identify the population structure and also makes it quite easier to make assumptions about a country’s future prospects. These pyramids lend so much validity and sense to the statistics for social scientists and policymakers. Though pyramids help to understand statistics, it is claimed by Rosling that making wise investments in improving the lives of the most socially disadvantaged people can greatly help to keep a check on population growth. He claims in his lecture that even in 1960 when world population was 3 billion, 2 billion was made... up by the...
