For instance, overpopulation and population growth place a tremendous amount of pressure on resources, which result in a chain reaction of problems as the nation grows. The third school of thought is that population growth does have any impact on economic growth. In Kenya, 71.8 percent of the total Kenyan population is in the labor force which includes all people, age 15 and older who supply labor for the production of goods and services at a specified time. It includes both the employed and unemployed. The economically active population is projected to increase from 17,825 (80.9 percent) in 2008 to 24,821 (81percent) in 2020.
The rate of urban growth in Africa is very alarming and the continent is said to have the highest rate of urbanization globally, at 4.4% per year (Gwebu, 2004)[ ]. In the year 2000, owning to the combined effects of rural-urban migration and rapid rates of natural increase, 38% of the continent’s population lived in urban areas and the proportion was expected to increase to 47% by 2015 (Thuo, 2010). Urbanization in Ghana is not different from other African countries. In 2000, 43.8% of the population constituted urban dwellers with a growth rate of 2.6% per annum as against 23.1% in 1960 (GSS, 2000)[ ]. Though the rate of urbanization in Africa is projected to rise to over 50% by the year 2030, Ghana has already achieved this with 51.5% of its population already living in urban areas (United Nations, 2008)[ ].
The issues of global climate change and global warming have attracted more and more concerns. It is commonly agreed that CO2 is the most important and critical anthropogenic greenhouse gas (GHG). The predicted growth of global economy and world population in the near future will lead to an increased demand for energy , resulting in an even further increase in the atmospheric CO2 concentration . In recent years, the amount of CO2 liberated by the utilization of fossil fuels has been over 30 gigatonnes. Global GHG emissions have doubled since the early 1970s, and the emissions would double again by 2050 without appropriate and effective emission abatement.
A decade ago, world population was growing by 1.24 per cent per year. Today, it is slowly growing by 1.18 per cent per year, or approximately an additional 83 million people annually. The world population is projected to increase by more than one billion people within the next 15 years, reaching 8.5 billion in 2030, and to increase further to 9.7 billion in 2050 and 11.2 billion by 2100. (Esaunorg, 2015) This human population growth around the world will affect people through its impact on the economy, environment and standard of living in relation to the country’s development. At this current rate of population growth is now a significant burden to human well-being.
dollar since 1983, came under speculative pressure because Hong Kong's inflation rate had been significantly higher than the United States' for years. Monetary authorities spent more than $1 billion to defend the local currency. Since Hong Kong had more than $80 billion in foreign reserves, which is equivalent to 700% of its M1 money supply and 45% of its M3 money supply, the Hong Kong Monetary Authority (effectively the city's central bank) managed to maintain the peg. Stock markets became more and more volatile; between 20 and 23 October the Hang Seng Index dropped 23%. The Hong Kong Monetary Authority (HKMA) then promised to protect the currency.
Not only is 82 percent of the global population from developing countries, but with a growth rate 15 times greater than developed countries it is believed they will provide 97 percent of the population growth by 2050. For example, the global average of live offspring per female is 2.5, while some African nations average 7, or more. There are numerous reasons for these dramatic differences. Through the promotion of health and education, improvements in property and civil rights, and increased available options for women outside the home, deliberate limits have been placed on family size, through delayed marriages, birth control options, and even abortions. Although improvements have been made, families in many developing nations have limited access to family planning services and educational opportunities for women.
And since then, international tourism has been multiplied by 50 compared to 1950, and has reached 1,186 million tourist arrivals in 2015. The forecasts are striking as they expect 1.8 billion tourist arrivals by 2030, due to a growth of 3,3% per year between 2010 and 2030. Concerning the domestic tourists, UNWTO estimates the
Introduction The population has been increasing exponentially with the world population hitting the 7 billion mark in 2012. Least Developed Countries (LDCs) accounted for 97% of this growth (United Nations, 2015). There are currently 48 LDCs, all of which are suffering from extreme poverty and high fertility rates. As poverty increased, so did birth rates (Central Intelligence Agency, 2016), reflecting poverty as a major cause for overpopulation. This leads to issues regarding resource scarcity like overcrowding, water scarcity, and food scarcity.
In the past few years, scientist have put the numbers of our ever-growing human population under a magnifying glass. There has been a substantial amount of growth and It 's leading to overpopulation. “Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth.” (Overpopulation) There are many causes for concern when viewing the numbers and effects because the overall population will suffer shortages of basic needs such as food, energy, and most importantly water. It took thousands of years for the American population to reach a billion in 1804. It took only one hundred and twenty-three years to reach two billion in 1927, and forty-seven years to reach four billion in 1974.
Population explosion and its potential perils continue to be a key concern for countries world over and especially the developing nations. According to the recent study by the United Nations, indications are that population growth has been at an infinitely faster rate in the recent past. While it took the global population centuries to reach the first 1 billion mark finally in 1804, the last billion mark i.e. 7 billion in 2011 was reached in barely 25 years. Judging by this rate of growth, it is expected to go up by another 2 billion by the time we reach 2050.
