The Population Of Humans On Earth - 1468 Words

Population Throughout most of human history, the population of humans on earth has been kept in check by environmental factors. With humans relying completely on the resources near to them, if a population began to grow too large it would be held back by a need for resources such as food and water. Once a civilisation grew large enough to have the food produced outside of larger cities and sold to the people in the cities, Diseases were the main factor holding population in check. However in the early 1800’s, the population of the world increased drastically due to advances in medicine that greatly increases the expected lifespan as well as reducing the infant death rate. In today’s world, the population is growing at a rate that is devastating to the earth. The United Nations has projected a population of nine billion people by 2050. In order to see how the effects of this growth can be reduced and reversed, one must examine the impact it will have on basic needs such as food, water, and energy. One major need for the survival of the human race is water. Every day, more than one billion people on earth lack access to safe, clean, drinking water. Though the majority of the earth of covered in water, less than three percent of it is fresh water. Much of the freshwater on earth is frozen in the polar ice caps or in glaciers. Due to this, less than one percent of the total water on earth is fresh and available for drinking. At this point in time over half of this water isShow MoreRelatedGlobal Warming And Its Effects On Human Population1458 Words   |  6 Pagesyears, the population of the world has gone from about 2 million people to just over 7 million people. With this drastic change in population in such a short period of time compared to the total age of the earth, problems are no doubtable going to arise. From the demand of the ever rising human population on the earth, food accessibility, depletion of natural resources, and an increase in global warming affects all have detrimental consequences on our human population and our own earth that may notRead MoreHuman Neutering And Its Effects On Humans1224 Words   |  5 Pagestwenty-five. All humans being unable to reproduce at a certain age could save the Earth. The Earth is in a very fragile state; Earth is losing its ability to be a habitat for the human race due to the volume of people living on its surface. There could be a way to slow down this process though, through human neutering. Human neutering would decrease overpopulation, allow the earth to reproduce its natural resources, and stop deforestation from rapidly occurring. A form of human neutering does existRead MoreEarth s Impact On Earth1201 Words   |  5 PagesHumans have changed the face of Earth from the moment they first arrived. We humans who rule the earth and live in the earth have changed in many ways; ever since we came we have had growth in population, impact has been greater. We cut down forests, emitting pollutants, spilling oil, burying toxic waste, dumping garbage in oceans. We have affected this earth in a very positive and a negative way ever since we arrived on this planet called earth.

In 200 years, the population soared to 6 billion (Berg Hager, Chapter 1, 2009). With industrialization and technologies developed in those 200 years, humans have been depleting the earth’s natural resources at an alarming rate. Environmental science is the branch of science concerned with the physical, chemicalRead MoreI Will Be Defending The Earths Current Population1386 Words   |  6 PagesEarth has been around for 4.5 billion years, progressing through several eras and phases. However, questions have begun to appear, with questions if the â€Å"Earth is Overpopulated?†, if â€Å"With the Earth’s Current Population, will it be capable of maintaining life at a sustainable level?† (Heaton), and if the Earth is at risk of running out of resources at the rate we’re consuming them? My answer to all these questions is no, that although the population is currently at 7 billion people, it is not atRead MoreOverpopulation : The Biggest Flaw Of The Human Population1627 Words   |  7 Pagesare enough resources to supply the unlimited demand of the human population. The real problem is not that the resources of earth can’t sustain the population, but that they are not used efficiently enough. The fluctuating population densities and the means to efficiently use the resources are some of the biggest flaws of the human population. When overpopulation is debated about the main concerns besides the plight of the dense populations are the birth rate, standard of living, and ecological well-beingRead MoreThe Overpopulation Of The Human Race1377 Words   |  6 Pagesthe human race is killing the earth due to the consumption of natural resources and not taking care of our planet. The human race as of the twenty-first century is similar to a parasite. Humans consume everything we can and do not help those resources grow back. The human race is also driving animals ou t of their habitats, taking over those habitats and in that process putting more animals on the endangered species index. The human population needs to be reduced in order to try to save earth or soRead MoreImproving Urban Sanitation And Waste Removal985 Words   |  4 PagesHuman population has grown very slowly for most of its existence on earth. Scientists currently estimate that modern human beings evolved roughly 130,000 to 160,000 years ago. Many threats, from diseases to climate fluctuations, kept life expectancy short and death rates high in pre-industrial society, so it took until 1804 for the human population to reach one billion. From that point forward, however, population growth accelerated very quickly. Through the early decades of the Industrial RevolutionRead MoreThe Space Settlement Of Space880 Words   |  4 Pages1.1 What is a space settlement The human civilization, after centuries of existence is now facing problems on earth and is in need of a new home, the space settlement. Space settlement is a simple concept developed to overcome the dangers which the human species is facing and would face in the future. It is a complex structure providing the essential needs for a person to live, which is constructed in space. In simple words, a habitat in space. It would be something where people would live, workRead MoreHuman Population Growing Every Day Essay1354 Words   |  6 PagesWith the human population growing every day, can Earth support all of the additional population? If the answer is no, is it as simple as just changing or life or are there simply to many people on the planet? This question is brought up a lot when talking about human population and other questions are usually brought up like: is there enough space, is there enough food, is there enough water, what are we going to do if we run out of natural resource s, and what are we supposed to do with all of the
