The unsustainable growth in population and its negative effects on the environment

This has huge implications on the workforce, as well as government spending on pensions and health care.

Two regions account for most of the deficit, South Asia and sub-Saharan Africa. Would they be scraping by on the bare minimum of allocated resources, or would they have the opportunity to lead an enjoyable and full life?

Consumption trends are somewhat more difficult to predict because they depend more heavily than population projections on global economic conditions, efforts to pursue sustainable development, and potential feedbacks from the environmental systems upon which the global economy depends for resources and sinks.

Population and environment relationship

Also consider that population growth is most rapid in part of the world where water is in high demand already, such as Africa, Southeast, Southwest, and Central Asia, and Oceania. In the world population is more than 7. Oddly enough, the overpopulation of an area can occur without a net gain of population. At the other end of the spectrum, policies that encourage family planning, education, gender equity and other measures to help slow population growth will help reduce pressure on the planet. Neo-Malthusianism underpins the Club of Rome World Model mentioned above 9 and implicitly or explicitly underlies many studies and frameworks. The United Nations estimates that the world population will reach 9. For most of our existence the human population has grown very slowly, kept in check by disease, climate fluctuations and other social factors. Launched Wild Energy , the Center for Biological Diversity's vision for a renewable energy future that addresses climate change while protecting sensitive wildlife and habitats. Some also group IPAT in this category because population is only one of the three variables contributing to environmental impacts. In the case of neo-Malthusianism, population growth is the primary problem, and the solution is population programs. Many political ecologists see population and environment as linked only insofar as they have a common root cause, e. The reverse was also true—for example the population of North America grew only 4 per cent between and , while its carbon emissions grew by 14 per cent. Similarly, as the incomes of individuals in developing countries increase, there is a corresponding decrease in birth rates. Unfortunately, many theories in the realm of population and the environment have not been subjected to the level of rigorous empirical testing that would allow them to be categorized as robust. In , a hectare of cropland yielded on average 1.

While the interconnected problems of population growth and environmental issues seem overwhelming, it is important to remember that humans can make changes that positively impact the planet. In the case of CO2 emissions and footprints, the per capita impacts of high-income countries are currently 6 to 10 times higher than those in low-income countries.

The unsustainable growth in population and its negative effects on the environment

Political ecology also frequently informs the population-environment literature Biodiversity loss is already leading to wars, political destabilisation, and international tension. In the concluding section, we relate population-environment research to the emerging understanding of complex human-environment systems. Many political ecologists see population and environment as linked only insofar as they have a common root cause, e. The Biggest Impacts The use of resources and the impact of environmental issues are not equal around the globe. For visualization, during that same 20th century that saw fourfold population growth, CO2 emissions increased twelvefold. In , Paul Ehrlich published The Population Bomb 8 , which focused public attention on the issue of population growth, food production, and the environment. While a lot of positive steps are being taken to better ensure the sustainability of humans on our planet, the problem of having too many people has made lasting solutions more challenging to find. While many enthusiasts for centralisation and urbanisation argue this allows for resources to be used more efficiently, in developing countries this mass movement of people heading towards the cities in search of employment and opportunity often outstrips the pace of development, leading to slums, poor if any environmental regulation, and higher levels of centralised pollution. Great Victorian visionaries — Edwin Chadwick, Joseph Bazelgette, and John Snow — connected these conditions with the disease, pestilence, and social disruption.

Africa, which has the fastest growing population of the continents, is projected to more than double the number of its inhabitants in the next 43 years—from million to approximately 2 billion.

But how many people is too many? People in developing countries tend to feel the impacts of environmental problems more acutely, especially if they live in coastal areas directly affected by sea level rise and the extreme weather events that accompany climate change.

Generated momentous media attention on the often ignored issues of human population and overconsumption in top outlets, including The New York Times, The Los Angeles Times, The Huffington Post, The Washington Post, Mashable and dozens of radio and podcast appearances.

Population income is also an important consideration.

human population and environment notes

It explores the ways in which demographers and other social scientists have sought to understand the relationships among a full range of population dynamics e. Abstract The interactions between human population dynamics and the environment have often been viewed mechanistically.
