Lawrence THE HANDLE, which varies in length according to the height of its user, and in some cases is made by that user to his or her specifications, is like most of the other parts of the tool in that it has a name and thus a character of its own. I call it the snath, as do most of us in the UK, though variations include the snathe, the snaithe, the snead, and the sned. Onto the snath are attached two hand grips, adjusted for the height of the user. On the bottom of the snath is a small hole, a rubberized protector, and a metal D-ring with two hex sockets.
Shop What is Overpopulation? Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation.
It is possible for a sparsely populated area to become densely populated if it is not able to sustain life. Growing advances in technology with each coming year has affected humanity in many ways. One of these has been the ability to save lives and create better medical treatment for all.
A direct result of this has been increased lifespan and the growth of the population. In the past fifty or so years, the growth of population has boomed and has turned into overpopulation. In the history of our Human population control essay, the birth and death rate have always been able to balance each and maintain a population growth rate that is sustainable.
Between the time of the plague and the 21st century, there was been hundreds and thousands of wars, natural calamities and man-made hazards. However, none of these have made a dent on the population. Developing nations face the problem of overpopulation more than developed countries, but it affects most of the Earth as of now.
When we are talking about overpopulation, we should first understand the causes of it. Causes of Overpopulation Decline in the Death Rate: At the root of overpopulation is the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize.
Talking about overpopulation shows that while there are many factors that can increase the death rate for short periods of time, the ones that increase the birth rate do so over a long period of time.
The discovery of agriculture by our ancestors was one factor that provided them with the ability to sustain their nutrition without hunting.
This created the first imbalance between the two rates. Following this came the industrial revolution. Technological advancement was perhaps the biggest reason why the balance has been permanently disturbed. Science was able to produce better means of producing food, which allowed families to feed more mouths.
Medical science made many discoveries thanks to which they were able to defeat a whole range of diseases. Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines.
Combining the increase in food supply with fewer means of mortality tipped the balance and became the starting point of overpopulation. More Hands to Overcome Poverty: However, when talking about overpopulation we should understand that there is a psychological component as well.
For thousands of years, a very small part of the population had enough money to live in comfort. The rest faced poverty and would give birth to large families to make up for the high infant mortality rate.
Families that have been through poverty, natural disasters or are simply in need of more hands to work are a major factor for overpopulation.
As compared to earlier times, most of these extra children survive and consume resources that are not sufficient in nature. Technological Advancement in Fertility Treatment: With latest technological advancement and more discoveries in medical science, it has become possible for couple who are unable to conceive to undergo fertility treatment methods and have their own babies.
Today there are effective medicines which can increases the chance of conception and lead to rise in birth rate. Moreover, due to modern techniques pregnancies today are far more safer.
Many people prefer to move to developed countries like US, UK, Canada and Australia where best facilities are available in terms of medical, education, security and employment. The end result is that those people settle over there and those places become overcrowded.
Difference between the number of people who are leaving the country and the number of people who enter narrows down which leads to more demand for food, clothes, energy and homes.
This gives rise to shortage of resources. Though the overall population remains the same, it just affects the density of population making that place simply overcrowded. Lack of Family Planning: Most developing nations have large number of people who are illiterate, live below the poverty line and have little or no knowledge about family planning.Population and Sustainability: Can We Avoid Limiting the Number of People?
Slowing the rise in human numbers is essential for the planet--but it doesn't require population control. What is population control?
Population control is any methodology used to control the type, location and number of people that inhabit the earth.
Population control refers to the practice of artificially altering the rate of growth of a human population. Historically, this has been made possible by limiting the birth rate, usually by government mandate.
It-) has been undertaken as a response to factors including high or increasing levels of. Regardless of criticisms against the theory that population is a function of food availability, the human population is, on the global scale, undeniably increasing, as is the net quantity of human food produced — a pattern that has been true for roughly 10, years, since the human development of agriculture.
Human population planning is the practice of intentionally managing the rate of growth of a human feelthefish.comically, human population planning has been implemented with the goal of increasing the rate of human population growth.
