Introduction Human population control is the practice of artificially altering the size of any population. (Human Population Control, n.d). It typically refers to the act of limiting the size of a human population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology (Human Population Control. This is done as a response to factors including high or increasing levels of poverty, overpopulation, and environmental concerns. Therefore, it is important to control population size as a response to the above-mentioned problems/factors, these factors are the subtopics that we will discuss in depth in this assignment. Reducing the size of a population …show more content…
Human overpopulation is among the most pressing environmental issues, such as global warming, environmental pollution, habitat loss, the sixth mass extinction, intensive farming practices and the consumption of finite natural resources, i.e. fresh water arable land and fossil fuels, speeds faster than their rate of regeneration, so if human population is controlled this will not be a problem (Tsiattalos, 2014). This is why we apply measures to reduce the adverse impacts of overpopulation i.e. mitigation measures, such as spreading awareness and education about overpopulation, enacting birth control measures and regulations, and providing universal access to birth control devices and family planning, must be taken. In countries like China, the government has put policies in place that regulate the number of children allowed to a couple, and some leaders and environmentalists are suggesting that the United Nations implement a China-like one-child policy globally to help control and reduce overpopulation gradually. Others, such as Gerard K. O'Neill, Marshall T. Savage and John S. Lewis, have suggested building space habitats in asteroid belts or the Venusian atmosphere as viable solutions to successfully sustaining current population growth rates. Stabilizing human overpopulation, outside of relying on an …show more content…
According to global outlook for water resources to the year 2025, it is estimated that by 2025, more than half of the world’s population wil be facing water based vulnerability and human demand for water will account for 70% of all available fresh water (Tsiattalos, 2014). Increased Habitat Loss According to (Michae, 2011) habitat loss is when land cover, or its aquatic equivalent, is changed, usually as a result of changing use by humans. Whenever we humans take over natural areas for our own use, we are encroaching on the habitat of another creature and progressively we are doing this at an alarming rate. The world's forests, swamps, lakes and other habitats continue to disappear as we make way for agriculture, housing, roads, pipelines and all the other hallmarks of industrial development. Human activity is responsible for the loss of around half of the forests that once covered the Earth. Although these can recover and can even be sustainably harvested, their rate of loss is about ten times higher than the rate of
Deforestation is still an unbeleafable issue even to this day. With our trees being cut down to make supplies and furniture, we struggle with keeping our ratio of trees being destroyed and trees being planted equal. It seems like that was also the case in the past. There was a significant amount of trees being cut down in 1920, the land looking much more barren than it did in 1650 (Document A, map). These trees, some of them taking more than three thousand years to rise tall, are being cut down.
The effect of reduced forest size has already had a measurable impact on the composition of our atmosphere in the relatively short amount of time we have been cutting them down(6). Ironically however it is the conversion of forest land to urban and agriculture use that has a more permanent and detrimental impact. Logging and urbanization lead to forest succession. Forest succession happens when there are changes to an environment that causes the composition of plant and animal species to change. New species succeed the existing ones as a result of things like changes in amount of shade, temperature, or the introduction of foreign species.
In 1960, a man named Paul Ehrlich shared his fears of overpopulation in the world through his book called, “The Population Bomb”. He made many predictions about what kind of disasters we would face if drastic measures were not taken. Zero Population Growth became a political movement that wanted to limit births and give rewards to couples without children. However, humanity has managed to survive even with the current population growth. Paul Ehrlich believes that even though his predictions didn’t happen, it doesn’t mean he was wrong.
Malthus’s Essay on the Principle of Population was an influential essay that proposed a systematic theoretical approach to population. Malthus had collected empirical data and proposed that human population growth increases at an exponential rate. Whereas, the production of food increases at an arithmetic rate. This means that in the long run arithmetic food growth coupled with an exponential growth of human population would lead to a future where humans have little to no resources to survive on. To avoid this Malthusian catastrophe, Malthus argued for controls on population through preventative and positive checks.
Why Population Control is Needed While it is not a fact that bigger families are happier, it is a fact that the Earth is running out of space. With an estimated 7.3 billion people living on this planet as of now and 2 billion more people are estimated to join the current population by 2050, the world does not have the space nor the resources to keep these many people happy. Whether people like it or not, something has to be done about the growing human population. If the human population continues to grow without anything to slow the growth, humans will die out along with the Earth.
Thankfully, this problem is solvable by humans, given that a few things change. Educating people more brings awareness to the perils of overpopulation. Also if there is more widespread acceptance and easily accessible contraceptives would slow down the average birth rate. Finally, the government could intervene to stop too many children from being born. While overpopulation is a very complicated international problem, if we as a human race start taking initiative to try to improve this situation, we will surely be able to stop the overpopulation that destroys our natural
When deforestation occurs, the wood of trees releases extensive amounts of carbon dioxide that only adds onto the greenhouse effect. An example of deforestation comes in the form of urbanization and the act to industrialize further within a country. In the last thirty years, India’s forest only covers 21 percent of the nation (23,716 Industrial Projects, 2016). Based on governmental information and data, lands are being curbed aside in order to organize commercial projects. These acts aren’t just happening in India.
However, limiting the population's growth promises only benefits for the stability of the world's natural equilibrium. The government has two basic methods of limiting the increasing percentage of the population. The first is by
‘’The environment is in us, not outside of us. The trees are our lungs, the rivers our bloodstream. We are all interconnected, and what you do to the environment ultimately you do to yourself.’’ - Ian Somerhalder. Ultimately, anything we do to the earth will cause weakness within it, and we’ll chip away at this incredible planet until eventually, it won’t be able to sustain us, the human race. The more we take from the earth due to our greed will cause problems that don’t have easy fixes to them, and deforestation is one of them.
Overpopulation Overpopulation is a condition that is undesirable. Overpopulation is one of the problems that people concern it to. One of the serious countries facing this problem is China. Reports in China show that it has about 1.4 billion people in this country; it takes about one over seven people of the world population. China is the third largest land after Russia and Canada in the world.
Topic: Water Shortage Specific Purpose: To inform the audience about water shortage and how to cope with water scarcity Thesis Statement: Across the globe, reports reveal huge areas in crisis as reservoirs and aquifers dry up. I. INTRODUCTION A. Turning off the water while brushing their teeth, a family could save about 5 to 10 gallons of water per day. B. Freshwater shortage will cause the next great global crisis.
Introduction Overpopulation is the excessive population of an area to the point of overcrowding and it is an undesirable condition in every country where the number of existing human population rises to an extent exceeding the carrying capacity of ecological setting. Overpopulation can be result from an increase in births, an increase in immigration, a decline in mortality rates and other factors that may cause overpopulated environment. Therefore, this can cause influence as lack of the available essential materials for survival like water, shelter, social amenities and other because of the numbers of people might be more than the materials for survival. In such condition, this regularly contributes to environmental deterioration, worsening
Although the exponential growth model is the basis of this model, population ecologists have developed this to model the reality of limited resources. This model illustrates how a population may increase exponentially until it reaches the carrying capacity (the number of individuals of a particular species than an environment can support) of its environment. The logistic growth model looks like this when it is illustrated
Without the transpiration of trees, deforested areas become drier. Changes in weather and shelter cause deforested areas to undergo a tremendous loss of biodiversity. The scientist hasn’t even come close to testing 1% of the plants in the tropical rainforests for medicinal use, but they regularly discover species that are helpful to us the people. But, these forests and their potential benefits are looking like they may disappear by the end of this century if we don’t stop
When animals lose their habitat (Anadiplosis), they are not accustomed to their new surroundings and could potentially go extinct. Species depend on forests to survive and when the forests are cut down, the animals have nothing left. Forests are heavily depended on for resources and ways of life. The Pachamama Alliance Organization claims that, “the tropical rainforests of South America are responsible for 20% of earth’s oxygen.” This proves the earth relies greatly on forests and may suffer consequences because of the speedy rate trees are being cut
