Freshwater ecosystems have lost a greater proportion of their species and habitat than ecosystems on land or in the oceans; in addition, they are probably in greater danger of further losses from dams, pollution, overfishing, and other threats. In extent, freshwater ecosystems are quite limited, covering only about 1 percent of the Earth’s surface. Yet, they are highly diverse and contain a disproportionately large number of the world’s species." Freshwater life zones that provide important natural resources and natural services to human is being damaged and degraded by humans. • Increased habitat loss.
Changes take place in every part of the world, every economy, every country or every household and so does the population. A population is the total number of people inhabiting a particular place, region or country. With around 7.3 billion people in the world at the current time, the population keeps on rising upward, and it usually affects poor and underdeveloped countries and their economies, people or the environment. It is a natural process. Rich and developed countries, on the other hand, have sustained the limit of the population growth.
Introduction Does human population growth affect our world? This has been an ethical dilemma for scientists for many years, and it seems they don’t have any solution to it yet. Human population growth has brought a lot of effect on our world, negative and positive impact. It depends on the environment of the specific area, for example, if an area is under populated, it will need population growth to have the man power in that area ( Aiex, 1994).If the area is overpopulated, population growth will be hazardous because there will have scarce resources in that particular area. In this essay, I will discuss two sides of the dilemma examining each position (pro and cons) critically.
Approximately 50% of the worlds’ population will be living in regions around the globe that are considered “water stressed”, either due to lack of it, or poor quality, by the year 2030 (compared to 15% currently). Water is a fundamental and integral part of human survival. We imbibe it, cook with it, bathe in it, and use it to filter and dispose of sewage. As the global population is expected to keep growing in the coming decades, the negative impact that humans will have on earths finite resources, especially water, will become increasingly apparent as areas of the world will start to experience drastic shortages of water, leading to instability in food production, industry, social order, and political and military
The Earth produces a limited amount of fresh water and food, which is falling short of the current needs. When population growth increase, the living standards decrease because they consume resources faster than they can regenerate. Many developing countries with rapid population growth face the urgent need to improve living standards. While the populations are expanding, our demand for health care, food, fresh water and shelter have increased. According to Miller and Spoolman in Sustaining the Earth (2015), we are about 7.1 billion people on the planet and this number will increase to 9.6 billion by 2050.
Population growth is rate at which populations increase in size, population grows exponentially. After studying the rates at which different countries populations would double, my eyes were opened to the main issues of population growth. The main issues include not enough space per person in area i.e. overcrowding, the fact that food growth is at a slower rate than the increasing amount of people there is to feed, inequality of resources and causes natural resources to decline, such as water and trees. The issue of population growth and over population that was most challenging to me was the lack of solutions to the issue.
This striking growth was largely caused by an increase in the number of people living in the age of fertility and accompanied by significant changes in fertility rates, which increased urbanization and accelerated migration. These trends will have broader implications for generations. In this study, we will examine the causes and effects of rapid population growth and the studies that the United Nations has done for the solution of this problem. First, we will examine the reasons for the rapid population growth after the information on the regions where the population growth rate is high and the population is intensive, and finally the studies of the United Nations for the solution of the problem. Summary of World Population China and India: Most Populated Countries Sixty percent of the global population is in Asia (4.4 billion), 16 percent in Africa (1.2 billion), 10 percent in Europe (738 million), 9 percent in Latin America and the Caribbean (634 million)
Fresh water makes up less than 3% of all the water on earth. Not all the water in the world is drinkable. Water is a valuable resource. However, there is an increased paucity of usable water with the levels of pollution and more so, the immense wastage of water we do and see getting wasted every day. Water is a scare resource in various parts of the world which makes us realize its importance.
The growth in human population around the world affects all people through its impact on the economy and environment. The current rate of population growth is now a significant burden to human well-being. In the past, infant and childhood deaths and short life spans used to limit population growth. In today 's world, thanks to improved nutrition, sanitation, and medical care, more babies survive their first few years of life. Rapid human population growth has a variety of consequences.
Every human being needs natural resources such as water to support their lives and protect environmental quality. We desperately depend on water for drinking, energy, agriculture and transportation. The need for clean water is considered as continous and unlimited demand. Due to the importance of the need for clean water, it is a common thing if the water sector is addressed as a high priority. From time to time, the water supply and service are getting increased which sometimes imbalance with the service capability.
