Saving Human Population from Crashing
Of all species that inhabit the earth, human beings are responsible for negatively impacting its natural landscape the most. Currently, the global human population stands at over 7 billion (Relethford, 2019). It is evident that this population should not be allowed to continue growing indefinitely given the limited nature of life-sustaining resources found on the planet. The carrying capacity is a term used to refer to the maximum population of a given species that the ecosystem can support indefinitely. According to the views of most scientists, the carrying capacity of the Earth lies between 9 and 10 billion people (Cohen, 1998). The United Nations projects that the total world population is expected to hit 9.7 billion people by 2050 and 11.2 billion 50 years later thereby exceeding the estimated carrying capacity (United Nations, 2015). If the world’s population was allowed to expand indefinitely, it will reach a size where it will be limited by a shortage of resources such as water and factors such as space and nutrients, or by adverse conditions that may include drought and diseases. These factors are known as environmental resistance and can lead to the extinction of the human race. It is evident, therefore, that there is a need to devise a plan to save the human race from crashing by controlling population growth.
The planet Earth lacks the biocapacity to sustain the present high levels of growth accompanied by massive consumption of resources. To address the challenge and save human the human population from crashing, the suggested plan focuses on improving and availing technology such as contraceptives, slowing population growth, and changing global culture regarding the size of a family. A combination of these strategies will promote access of contraceptives by individuals within the reproductive age, develop economies of different nations, empower women, save children from early death, and educate men. This initiative will help to regulate the population of human beings, reduce their negative impact on the planet by addressing consumption habits, and contribute to improved quality of life for everyone.Saving Human Population from Crashing
Throughout the history of the world, the human population increased at a rate that just surpassed slightly the replacements levels. In the few centuries, however, there has been a tremendous decline in mortality which in turn has given rise to a dramatic increase in the rate of population growth. According to Brander and Dowrick (1994), past experiences have demonstrated that achieving progress in development results to a fall in fertility. The developing world has recorded a very high rates of population growth than developed countries. The increase in population growth in developing countries could be attributed to insufficient economic progress and limited availability of social structures. As a result, the majority of developing countries have continued to record a decline in mortality without corresponding change in infertility. Since 1950, the annual growth rate of the world’s population has averaged above 2%. If the trend continues, the global population will double after every 35 years. Analysis of the national of population growth reviews that the rates vary widely and range from negative rates in some countries to over 3% in others. While developed countries such as Japanese have consistently recorded negative rates, developing countries continue to record high rates. The trend owes its origin to unequal socio-economic development that has persisted for many years. Additionally, although the increased rates of what population growth has been attributed to declining rates of mortality especially in developing countries, statistics indicate that the decline is unevenly distributed. In Latin America, for instance, life expectancy is 63 years. In Africa, it is 46 years while in Asia it is 57 years. Therefore, life expectancy in the developing world is considerably lower when compared to 71 years in developed regions.Saving Human Population from Crashing
While almost of te countries except China give couples the right to determine how many children they should have, many couples in different parts of the world have been unable to effectively exercise that right. Lack of knowledge on family planning, social norms, and difficult economic conditions have resulted in situations where a significant proportion of couples in developing countries are having more children then they will have desired. Based on the proposed initiative, it is recommended that governments in different parts of the world reconcile society’s aspirations and the reproductive behavior of individuals. In some large Asian countries such as Indonesia, the high population growth rates that have been recorded have been as a result of the desires of some couples to raise large families. Governments in such countries should come up with specific policy measure such as educating men and women on the benefits of raising a manageable family in order to control their present high national population growth rate.
Saving the human population will require focus to be given to educating women with the aim of reducing fertility. In developing countries, it has been found that women with education tend to have fewer children compared to those without any education. Contraception is a method that has been used effectively to regulate fertility. Therefore, governments should come up with a plan to make contraception easier to access. In Asian and African countries where a considerable population of young women gets married early, governments should consider raising the age of marriage. Apart from giving them a chance to attend school, it will help to significantly reduce and control population growth rate. Finally, governments in different countries could introduce incentives and disincentives to compliment various social programs and family planning initiatives aimed at regulating population growth.Saving Human Population from Crashing
