The Impacts of World Population Growth

The rapid growth of population is mainly the result of a higher birth rate than death rate. At the moment, the world population is said to reach 7.5 billion by the end of 2016 (Worldometers.info, 2016). The annual growth rate is actually declining, as it has been estimated that the population will continue growing by 1.13% per year (Worldometers.info, 2016) compared to a growth of 2% and above during the 1960s. However, this doesn’t mean that the population won’t continue its dramatic growth; as a matter of fact the world population should reach 10 billion by 2056 (Worldometers.info, 2016). The causes for such a population growth are mainly the decline in death rate, the lack of family planning and …show more content…

The main causes of deforestation include agriculture, urbanization and logging. The rise in population is resulting in a higher demand in food. In consequence trees are cut down so that farmers can have more land to plant crops so the food production increases. Then, as there are more people there needs more land for construction. This includes the construction of roads and highways, homes for the population and so on. Lastly, in order to provide the population with paper and wood, trees have to be cut down. For these reasons especially, 7.3 million hectares of forests are lost each year (Alina Bradford, 2015) and it is actually estimated that about 17% of the earth’s forests have been lost in the past 50 years (Kerry Cesario, 2016). Deforestation brings about a couple of detrimental impacts for our earth, this includes a loss in habitat which affects the biodiversity and also an increase in climate change. As around 70% (Alina Bradford, 2015) of the plant and animal species live in rainforests, when trees are cut down these species lose their habitat, in consequence this can lead to species extinction. As a matter of fact, forests contribute to reduce greenhouse gas emissions but when they are burnt, cut or removed in any other way they become carbon sources. Deforestation is actually the source of around 15% of greenhouse gas emissions …show more content…

As the population perceives an inequality concerning the distribution of food and water and also an inequality in income, this makes the people displeased or desperate. First of all, this leads to an increase in crime rate. As the poor need to ensure their survival, some rely on theft or get involved in the distribution of drugs in order to afford or get hold of their basic necessities : this includes the need for food, water, education or shelter. In addition, there will most probably be rising conflicts surrounding the fight for natural resources due to its constant depletion. As an increasing part of the population will become infuriated by the chaotic effects of population growth, there might be uprisings which could go as far as wars. Overall, we can tell that all the effects of population growth won’t only lead to these effects themselves, but they will also lead to even wider

    Alina Bradford from Live Science, explained in her article about deforestation and how there are different causes of deforestation such as, selling trees for products such as paper, homes, house hold furniture, and other house products. She also states that other causes of deforestation are making room for agriculture purposes, and to create room for cattle ranching as well. On the downfall though there are disadvantages of deforestation as well too as she explains. One of them in fact is deforestation is contributing to climate change and also the greenhouse effect too as well by emitting a great amount of carbon dioxide (CO2) into the earth’s atmosphere. The effect from that happening is carbon dioxide is a greenhouse which absorbs heat from the sun and doesn’t let it escape into space. As that doing so, the Earth is heating up each year due to deforestation. From that, it will cause global warming and climate change too. There are causes and different purposes for deforestation but there are significant effects that could end up due to deforestation based on Alina Bradford’s

  • Deforestation In The Amazon Rainforest

    958 Words  | 2 Pages

    Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .

  • How Does Population Growth Affect Population

    810 Words  | 2 Pages

    Population growth affects the earth just as much as it does the people. With the population continuously growing at an alarming rate, earth can’t keep up with the resources needed to survive. Eventually we will run out of oil, land to build houses, and air. The reasoning behind running out of air is if the world is covered in houses, there is no room for trees – which supplies our oxygen. The factors effecting population growth are: fertility rates, life expectancy, migration, and death rates. More and more people are migrating to North America because of the high life expectancy, average fertility rates, low mortality rates, and of course, job opportunity. Even though population growth isn’t as high as it used to be, overpopulation can still

    “The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests

    Farmers cleared away the trees for farm animals to graze which means deforestation is caused by growth. Forests assume a huge role in the carbon cycle on our planet. When forests are slashed down, not only does carbon absorption cease, but also the carbon which was stored in the burned trees is released into the atmosphere as CO2. Small crops for instance plants and agricultural crops also draw in carbon dioxide and release oxygen, however forests store up to 100 times more carbon than agricultural fields of the same zone. “It is estimated that more than 1.5 billion tons of carbon dioxide are released to the atmosphere due to deforestation and over 30 million acres of forests and woods are lost every year” Conserve Energy Future

  • The Effects Of Population Growth

    923 Words  | 2 Pages

    Growth is important in a society. If all the people meeting specific needs get too old to work or dies, there would be no one to take over that particular function. However, extreme growth could be a major problem and would be considered a latent dysfunction. The same could be said for environmental effects – some are to be expected and cannot be avoided, but too much would cause problems in the functioning of the population. Social conflict theory would view the problem with population growth as lying in the distribution of goods and unequal consumption. If everyone were using energy, water, food, and the like with the same careful consumption, there would be no problem with a larger population. However, some people, particularly those living in poverty, consume less and will still face the environmental issues that can arise, while the rich and powerful use too much and cause more problems. If the people that use more would act more socially responsible, there would be enough to sustain a population growth. Symbolic interaction theory would focus on the perception of the people in society and their views on things that affect the population growth and environmental changes. One example would be the contribution of having a large family to population growth, which could be prevented by birth control. However,

    Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.

  • Deforestation and Biodiversity

    2666 Words  | 6 Pages

    Deforestation, defined by biologist Charles Southwick as "the destruction of forests; may involve clear-cutting or selective logging" (p. 365), is a predominantly human-driven process that is dramatically altering ecosystems worldwide. "Clear-cutting" involves the indiscriminant removal of every single plant and tree species from within a selected area. The other major process of deforestation, "selective logging," focuses removal efforts on only specific, predetermined tree species within a chosen area. The statistics gathered about human deforestation over time are considerable, and they can be somewhat controversial. Depending on the source and the location selected, the magnitude of deforestation varies. Southwick estimates that, approximately 10,000 years ago, 6.2 billion hectares (23.9 million square miles) of forest existed on earth (p. 117). That figure is equivalent to 45.5% of the earth's total land. He further estimates that, by 1990, this amount had declined 30%, with only 4.3 billion hectares of forest remaining (p. 117). Southwick also acknowledges other estimates that place the total amount of deforestation between 50% and 75% (p. 117). NASA has similar deforestation statistics that confirm these trends. According to their website, 16.5% of the Brazilian Amazon forests have been destroyed. They also note similar magnitudes of deforestation in Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), despite the significantly smaller total area of forest within these countries. These grim figures are somewhat tempered by the NASA finding that, over the past ten years, the deforestation rate has declined from 6,200 square miles per year to 4,800 square miles per year. Though this trend is n...

    Human population growth is the leading factor we have in place to sustain a more perfect ecosystem for future generations. Over development has led to extinction, habitat loss and climate change that scars the Earth and will never be recovered again. According to the Center for Biological and Diversity we are adding 227,000 more people on top of the 7 billion everyday which is causing species to disappear 1,000 to 10,000 times faster than the rate of natural selection. It is time we get over our greed, religious biases and having more children equal’s more money mentality. The Earth and its ecosystem should be protected by every individual to keep it as pristine as the day they were born to pass off on future generations to inherit.

  • Cause-Effect Essay: Deforestation

    1146 Words  | 3 Pages

    People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation.

    Deforestation is the elimination of existing trees from the earth; attributable factors include urbanization, logging, ranching, and farming and to some extent land speculation. Land speculation can be included as cleared land is more valuable than forested land. Deforestation, done in the name of progress, and the long-term, devastating effects of it, is killing our planet.
