Zero population growth

Introduction Demography is the scientific study of human populations, including their sizes, compositions, distributions, densities, growth and other characteristics as well as the causes and consequences of changes in those factors. Demographic analysis is an important tool that explains sociological phenomena such as expanding population which can result in competition of resources such as food, land, access to trade routes among others. Demography largely relies on large data sets over long…

the Once-ler. He finds a forest that is host to “truffula trees”, he finds out that he can make sweaters from the tops of the trees. He starts out small, with just a shop, however, it grows into a large factory, thus decimating the “truffula tree” population. A similar situation is going on in Brazil. The Amazon has been shortened by twenty percent over the past forty years, as loggers, farmers, and ranchers use the land for their own gain. Both the Once-ler in The Lorax and the farmers in…

products to acquire goods they did not produce. Bernstein goes on to inform readers of the Athenian trade routes and the Peloponnesian war. The second part of the book mainly focuses on the transatlantic trade and the factors that contributed to its growth and development. Here, Bernstein takes readers on a journey covering this trade. Here, he informs us of the horrors of the slave trade, the rise of and fall of cities such as Genoa and Venice and the people who facilitated the trade such as…

When you think of the words “urban guerrilla” what are the first things that come to mind? In addition to those words, what are the first thoughts that come to mind when you see “out of the mountains”? These are the keywords that stood out to me when picking this book to read. With not having any prior knowledge of either of these two phrases, my mind began to wonder when I initially glanced over the title of this book. Let’s start with the phrase “urban guerrilla”. Carlos Marighella, a…

Destruction, and Habitat Loss (5) The obstacles of biodiversity loss, habitat destruction, and habitat loss are relatively new issues that stem from the expansion of human population and development. Before the expansion of the human population, humans did not have a large impact on their environment. However, as the current population pushes 7.6 billion individuals, humans are occupying a large percentage of the Earth, as well as consuming the majority of its resources. The result is a loss of…

The need to increase the number of adopted children is greater than ever. The adoption rates have drastically reduced; thereby, increasing the number of people aging out of the child welfare system without a relative or family to take care of them. Increasing the number of adopted children would reduce or eliminate the aging out of people from a child welfare system. As such, this paper looks into some of the ways by which to increase the number of adopted children; consequently, reducing the…

The world is full of people, too many some would say. With the world’s population currently at seven billion it is not hard to see that the population is surging. The number of people in an area must not exceed its carrying composite. With India being the second most populated country in the world, some say it has done just that. Over population is a problem that many people over look, now is the time to stop putting this problem to the side and face it head on before it is too late. The…

says that the world population has a slight percentage to just stop reproducing one day, when will that day be? Hardin makes a comparison to a lifeboat, and what I mean by that I that Hardin sees Earth as a lifeboat and the boat is slowly getting full. This shows his views on earth and how it is overpopulating. “But, one could argue, this discussion assumes that current population trends will continue, and they may not.” What Hardin means in this quote is that the population will never stop…

There has been an in-depth discussion about the state of the human population, mostly the effect of the Earth's carrying capacity has upon the global population. The carrying capacity of an environment is the maximum population size that can be supported by the resources available in the environment. Once an environment has reached this maximum capacity in regards to the resources, the population growth oscillates around the environment's carrying capacity. Density-dependent regulations mostly…

people living on this planet, so try putting that number into perspective. For years the thought of the growing human population exceeding earth’s capacity and number of resources able to sustain human life, has created this fear of “overpopulation.” Yet history has repeatedly proved that human capabilities far exceed the natural limits of the planet. Even as our population increases, humans have always sustained a contributing place in the world ecological order. The hard reality is…
