World population

In An Essay on the Principle of Population, Thomas Malthus warned that the growth of the world’s population would exceed the rate of food production. According to his theory, population increases exponentially while resources increase arithmetically. In other words, the land’s resources would eventually be unable to support everyone due to overpopulation. In order to control population growth, Malthus claimed that “moral restraint,” including abstinence and birth control, would lower the birth…

who are its victim.” In the world a very important issue is overpopulation. Many people are not aware of the human and environmental impacts this issue has. Overpopulation is probably one of the most important problems that need to be focused on. Hopefully, this will persuade you to take action and/or inform others about the impact of overpopulation. Currently, according to worldometers.info, there are about seven billion and three-hundred million people in the world. Around one-hundred and…

living environment. It is calculated by using the sum of the population’s age to divide by population. Life expectancy at birth simply means how long the newborn is expected to live under the current conditions of each country. A life expectancy of 50 years or less is considered low and anything over 75 years would be considerably high. The life expectancy of Australia(82) is one of the highest around the world and is the highest in the sample countries. All Australians are subsidized by a…

When discussing population and demographics, two opposite theories came to fruition, namely, the Cornucopian theory and the Malthusian theory. When looking at population issues, it makes far more sense for one to be pro-Malthusian than Cornucopian. This is due to the carrying capacity, positive and preventative checks, and overpopulation not leading to new innovations. The Cornucopian theory is optimistic to the point of naivety, and as such the Malthusian theory should be seriously considered…

TThe world Health Organization (2002) describes growth in the number of older people as “one of the humanity greatest triumphs” as well as “one of our greatest challenges”. The proportional growth of geriatric population in comparison to total population (described as graying of the world’s population) is a global phenomenon. In Australia, elderly population aged 65 and above currently accounts for 13% of total population which is estimated to be projected around 25% by 2056. The group aged 85…

economy. When looking at the expected population pyramids of Sub Saharan Africa and comparing it to that of developed area like Europe, we begin to see dramatic differences between the two regions. As of 2016, Sub Saharan Africa’s population pyramid currently displays the attributes of a stage 2 country in the demographic transition model where majority of the population is under 15 and is dependent on others until they going the working population…

realised that slum was not an inescapable urban future. In 1958 almost one third of Cuban population was residing in shantytowns. Huge wave was started for rehabilitation of the population. In third world countries, Nehru, Abdul Nasser and Sukarno also promised to rebuild slums and new houses. But this idea remained totally unclear because governments didn't pay any attention to address this problem. World Bank and IMF defined the reinforcement of the minimalist role of national governments in…

putting that number into perspective. For years the thought of the growing human population exceeding earth’s capacity and number of resources able to sustain human life, has created this fear of “overpopulation.” Yet history has repeatedly proved that human capabilities far exceed the natural limits of the planet. Even as our population increases, humans have always sustained a contributing place in the world ecological order. The hard reality is that common assumptions about…

The basic demographic equation is an effective way to determine future population rates, without the influence of political policy. The equation says that “growth rate = birth - deaths + net migration.” Europeans are dying out; their population is shrinking. One factor, fertility, has increasingly dropped. The European crude birth rate, or the number of births per 1,000 people, was 10.1 in the year 2014. Almost half a century before, in 1970, the birth rate was 16.4. Europeans seem to be…

Under population and Overpopulation When the number of people in a region or country is more than the available resources, the country or region is said to be overpopulated. In other words, overpopulation refers to the situation in which the country’s population is more than what its physical resources can support to maintain adequate living standards. Singapore, Israel, Kuwait, Lebanon, United Arab Emirates, Korea Republic, Jordan, Iraq, Belgium and UK are among the overpopulated countries of…
