Growth of Human Population and Its Effect on the Environment

The growth of the human population has been strikingly apparent that the rate of growth has been much steeper than recent times. The earlier Homo sapiens were vegetarians and gathers they hunted and fished for food. With increased knowledge humans learned how to farm, domesticate animals and used irrigation to meet their needs. The knowledge of water and sewer conditions along with better medical care and agriculture made life easier. Earlier man did not have these factors and the population remained stable, for over thousands of years. The Toba super volcano is believed to have caused a massive environmental change. Creating a bottleneck of the human population that â€Å"occurred about seventy thousand years ago.† (Wikipedia, para. 1)†¦show more content†¦Europeans colonized into other areas of the world bring with them diseases that would decrease the inhabitance of those regions. Life Expectancy With the improvement in medicine, agriculture and technology that has increased the average life expectancy. Like the children in this period once their nutritional and medical needs were met the percentage of children that died before the age of 5 has decreased In the new world after the war of 1776 came the new age of medicine called the vaccination which makes an enormous contribution to the mortality rate. With strides in cleanliness and improvements in the medical field which; saw the induction of antibiotics and other medicines. Penicillin revolutionizes the medical community to be the first drug to have curing capabilities on such diseases as Syphilis. With the introduction of anesthesia opened new possibilities for surgical improvements. The techniques for surgery improved after the introduction of anesthesia and once microorganisms were realized as being the cause of all infection and diseases. Instead of the doctor coming to the homes of the ill they built hospitals where patients would come to obtain care. Introduced to the medical community would be routines of cleaning, hygiene and sanitizing...Including sterilizing of instruments and washing hands became routine before any medical procedure could be performed. Another form of nutrition introduced wasShow MoreRelated Overpopulation, Industrialization, and the Degradation of the Environment934 Words   |  4 PagesDegradation of the Environment The overall growth of the human population in the last 2000 years has been a J-shaped growth. This can also be expressed as an exponential growth. A big question that can only be answered in time is how this population growth will slow down or stop. The planet can only handle so many humans before the effects of overpopulation send the environment into an unrecoverable tailspin of degradation. So the question is will the overall maximum human population be reached inRead MoreNegative Effect of Overpopulation.1365 Words   |  6 PagesTHE ADVERSE EFFECTS OF POPULATION GROWTH Some observers attribute nearly all of the world s maladies to excessive population growth. They claim that rapid population growth has at least three adverse effects on human well-being. First, it increases poverty--the number of people that are impoverished, the proportion of the community that is impoverished, and the severity of the impoverishment. Second, it increases environmental degradation--the misuse of natural resources--with adverse consequencesRead MoreEffects Of Population Pollution Essay1464 Words   |  6 Pages Population around the world is growing rapidly each year, which is unfortunately causing negative impacts on the environment. Each day the air around us is becoming more polluted as the amount of carbon dioxide emitted into the atmosphere caused by human activities increases each day. As population continues to gradually increase, it is causing harmful effects in terms of air pollution. An increase in the number of people directly varies with the pollution th at is emitted into the environment. MoresoRead MoreEssay on The Ecological Consequences of Global Economic Growth1426 Words   |  6 PagesGlobal Economic Growth â€Å"There have been five ‘ mass extinctions’ in the history of the earth, when between 65% and 95% of all species were wiped out, due to natural processes of selection and evolution. Some scientists now argue that we are heading for a ‘sixth extinction’, caused by the actions of humans.† (Cock and Hopwood, 1996:17) In the following I’m going to look at the positive and negative effects of the ecological systems of global economic growth and the Read MoreOverpopulation Is More Than Just A Crowded Planet1343 Words   |  6 PagesIn the year 1 A.D., the Earth’s population was 300 million. In 1850, after many decades of consistent population growth, it eventually surpassed one billion. From that point on in history, the world population began to climb rapidly (Haub). Each year, the world population surpasses what any scientist has ever thought possible. Some would consider this expansion as a sign of success considering the causes of a rapidly growing population include improved health care, new technology, progressive erasRead MorePollution Of The Environment And The Home1208 Words   |  5 Pagesof the Environment There is a strong connection between the environment and the home; this implication refers, in one aspect, to a human’s inclination and love towards home. Because of this connection one should be as concerned for the environment as one is towards his/her own home. Pollution can be defined as anything which is unclean. It causes a lot of environmental issues and health problems not only to humans, but to all creatures on the earth. If we more deeply consider the effects of pollutionRead MoreIntroduction . Many Factors Contribute To The Downfall1694 Words   |  7 Pagesof things, the changes have been negative and steadily declining with time. Among those factors, over-population would be one of the greatest contributors. The growth of the human population has continuously been on the rise. It has been predicted that it will increase even more throughout the years going from 7.2 billion to 9.6 billion (Gerland, et al. 2014). As the numbers of the human population increase the ecosystem is steadily declining because of the large demands of food and biofuels (LauranceRead MoreThe Environmental Impact of Overpopulation Essay862 Words   |  4 PagesThe human population has continued to grow through the decades. The increasingly large number of people that have become apart of the world population has become a major problem. The consequences of the world being over populated has numerous effects which include: Environmental effects, depletion of natural resources, effects on the economy, food and water instability, and mass species extinction. Without a solution to the rise in human population, by the year 2020, 8 billion people will liveRead More Overpopulation Essay582 Words   |  3 Pages There are 6 billion human beings on the face of the Earth. According to our best estimates, there are somewhere between three and seven times more people than this planet can possibly maintain over a long period of time. Non-renewable resources are being used at an incredible rate, and we are destroying the capability of the planetary ecosystem to renew the supply of renewable resources. The worse however is yet to come. We need to realize the necessity of a population plan which will make ourRead More Overpopulation of the Earth Essay1698 Words   |  7 Pagesnearly 6 billion people in the world. The world’s population has more than tripled in the span of a hundred years. Given that the earth’s population is constantly on the rise and seeing as how our natural resources are gradually being depleted, we must ask ourselves: what is to become of us and what is to become of our environment? In order to understand this question we must first have a thorough understanding o f whether or not there is a population crisis. Having understood this, we must then look
