The paper reviewed the impacts of population growth and the ways it affects aquaculture and fisheries prices. As the world population  continues to grow arithmetically, great pressure is placed on arable lands, water, energy, and biological resources to provide an adequate supply of food while maintaining the integrity of the ecosystem. In 2010, FAO projected the world population to double from 6.2 billion in October, 1999 to 12.5 billion in the year 2050. This had created serious negative impacts on the aquaculture and fisheries prices. At present fertile crop lands had been lost at an alarming rates while some abandoned during the past 50 years because erosions made it unproductive. Other vices such as food crisis, political unrest and war (Mexico, Uzbekistan, Turkistan, Yemen, Iraq, Afghanistan, Syria, Morocco and Sudan), civil strife and multiple years of draught (Niger, Mauritania and Senegal), impacts of HIV/AIDS Ebola, Lassa fever and Coronavirus the world over, clashes between cattle rearers and farmers and boko haram issues (Nigeria) as well as kidnapping and  corruptions have severely affected aquaculture and fisheries production and accompanied prices. Thus, this review was conducted to raise a cry for farmers and citizens to engage and participate in intensive culture and fisheries practices in order to fill the demand - supply gap so as to make fish food products available for the teeming masses.

The term ‘ecodisaster’ may be defined as ‘a global catastrophe of the human species’. Any ecodisasters occurring in the near future will, almost certainly, be caused, directly or indirectly, by the present overpopulation of the world, accompanied by unwise and irresponsible disregard of environmental deterioration.The suggestion is made here that Man's first and, it is to be hoped, last, ecodisaster may already have begun. Although not dramatic, it is taking the form of a steady decline in the standard of living nearly everywhere, coupled with massive pollution, and widespread malnutrition in the under-developed countries of the world. It will persist until world population eventually becomes adjusted to environmental resources.It is ironical that control of the pests and diseases which have inflicted so much misery on mankind in the past, should have helped to engender the present population explosion with all the hunger and privation that accompany it in the under-developed regions of the world.

The population of Africa in 1977 is estimated to be 423 million, which is about 10.3 percent of the world population. For a quarter of the world’s land area, that is a small population.Africa’s share of world population declined between 1650 and 1920, partly because the population of Europe and the Americas was increasing gradually through factors associated with the Industrial Revolution, and partly because of the ravages of the slave trade and the European colonial pacification measures. Since the 1920s, however, Africa’s population has been growing fast, and its share of world population could reach 13 percent by the year 2000.

Ultimately, the necessity to supply food, energy, habitat, infrastructure, and consumer goods for the ever-growing population is responsible for the demise of the environment. Remedial actions for pollution abatement, and further technological progress toward energy efficiency, development of new crops, and improvements in manufacturing processes may help to mitigate the severity of environmental deterioration. However, we can hardly hope for restoration of a clean environment, improvement in human health, and an end to poverty without arresting the continuous growth of the world population. According to the United Nations count, world population reached 6 billion in mid October 1999 (1). The rate of population growth and the fertility rates by continent, as well as in the United States and Canada, are presented in Table 14.1. It can be seen that the fastest population growth occurs in the poorest countries of the world. Despite the worldwide decrease in fertility rates between 1975–80 period and that of 1995–2000, the rate of population growth in most developing countries changed only slightly due to the demographic momentum, which means that because of the high fertility rates in the previous decades, the number of women of childbearing age had increased. Historically, the preference for large families in the developing nations was in part a result of either cultural or religious traditions. In some cases there were practical motivations, as children provided helping hands with farm chores and a security in old age. At present the situation is changing. A great majority of governments of the developing countries have recognized that no improvement of the living standard of their citizens will ever be possible without slowing the explosive population growth. By 1985, a total of 70 developing nations had either established national family planning programs, or provided support for such programs conducted by nongovernmental agencies; now only four of the world’s 170 countries limit access to family planning services. As result, 95% of the developing world population lives in countries supporting family planning. Consequently, the percentage of married couples using contraceptives increased from less than 10% in 1960 to 57% in 1997.

This chapter reviews population trends over the last two hundred years and population projections to the end of this century. In 2100 the world population will have stabilized but its geographical distribution will have substantially changed compared to 2015. The chapter then discusses the five stages of the demographic transition, and different neo-Malthusian and non-Malthusian theories of the relation between population growth and economic development. It emphasizes in particular the effects of rapid population growth on land and resource availability, human capital formation, population quality, the accumulation of physical capital, employment, wages, and income inequality. The effects of rapid population growth rate over a given period were found to change in line with the population size and density at the beginning of the period considered.

The past few years have evidenced a remarkable increase in the use of helicopters in agriculture. There are any number of individual reasons for this: helicopters are more plentiful, for example, but the primary reason is one of simple economics combined with a capability to meet new demands. The demands have been generated by the overwhelming population explosion. Sometimes hard to imagine and even more difficult to cope with, but the facts remain that:1.25 % of all the people that ever existed on earth are living on it today,2.The world population increases at a rate of 5400 people every hour; and3.This staggering number of people will double again within the next 40 years.

Through constant repetition over the past siderable credence has been given to a very pessimistic outlook for world agriculture. The pessimists argue that recurrent and ever more serious food shortages will occur as a result of increasing population growth, rising affluence, and decreasing availability of cultivatable land. Based largely on world consumption of food and feed grains ranging between 1.1 and 1.2 billion tons per year, with a yearly growth in volume of some 25 million tons needed to meet increased demand, it has been asserted that the world has twenty-seven days worth of food reserves left and is living on a razor's edge with respect to famine. This assertion does not bear up under close examination.

AbstractThis paper forecasts the world population using the Autoregressive Integration Moving Average (ARIMA) for estimation and projection for short-range and long-term population sizes of the world, regions and sub-regions. The study provides evidence that growth and population explosion will continue in Sub-Saharan Africa, tending the need to aggressively promote pragmatic programmes that will balance population growth and sustainable economic growth in the region. The study argued that early projections took for granted the positive and negative implications of population growth on the social structure and offset the natural process, which might have implication(s) on survival rate. Given the obvious imbalance in population growth across continents and regions of the world, a more purposeful inter-regional and economic co-operation that supports and enhances population balancing and economic expansion among nations is highly recommended. In this regard, the United Nations should compel member states to vigorously and effectively implement domestic and international support programmes with this objective in view.

As we observe the World Population Day on 11th July, the current population stands at roughly 7.9 billion in 2021, with India bagging the second place at 1.39 billion. The net growth rate stands at 1.1% or 83 million per year and the projected world population by 2050 is estimated to be 9.7 billion. These figures are alarming to us-the millennials, who grew up writing ominous essays on ‘population explosion’ at school. Governments across the world, historically Romania to more recently China, have adopted population policies to control the rate of population growth to cater to their advantage-either economically or politically. Some of them directly against reproductive rights- to decide freely and responsibly the number, spacing and timing of their children and to be able to do so without discrimination, coercion and violence.

The paper develops a mathematical model of population growth in an agricultural community, covering the 17th century ad. The model takes into account two types of resources that provided life, and the influence of management structures on population growth. The analytical results are compared with the estimated data of historians and economists on the world population. Based on the statistical approach, a model for estimating the possible dynamics of population growth is proposed.

Information and communication technology has changed rapidly over the past 20 years, with a key development being the emergence of social media. Social media alludes to all applications and websites or blogs that empower individuals around the globe to interconnect through the web, chat, and share substance, video call among numerous other functionalities it offers to its clients. For a individual to be a part of any social media, he or she has got to begin with signup and after that sign in to get to substance and be able to share and chat with other clients of that social media stage. Over the past two decades, social media have picked up so much development and popularity around the world to an degree that numerous analysts are presently inquisitive about learning more almost these social stages and their impacts on the community. Despite the reality that nearly everybody within the community is associated to at slightest one social media stage, the youth and young people are the driving and most aficionado of these social stages to the point that they indeed social organize whereas in course or indeed church. It is to this light that analysts have found that these social locales affect the lives of our youth in a society a extraordinary bargain in terms of ethics, behavior and indeed education-wise.
