Humankind will always have to overcome challenges. Three key challenges that we are currently facing and require immediate action are overpopulation, land use, as well as cultural conflicts. These issues have been prevalent topics in the media in recent years. Unless we start taking the steps to address these concerns, we will continue to see these topics in the media for years to come.
Overpopulation is a relatively recent issue. The world’s population has grown exponentially over the past twenty to thirty years. For example, the country of Bangladesh, with a population density of 1,188 people per square kilometer, has a 1.2% annual growth rate. Comparing these numbers with the United States’ population density of 34, and its growth rate of 0.7%, it is no wonder the country has an extremely high poverty rate, 31.5% according to the World Bank. As a result of this, certain areas have not been able to adjust to their changing population. The consequences of such an inability to adapt are poverty, crime, and an overall lower quality of life. Lagos, Nigeria is a city that best exemplifies this problem. With too few jobs and such a high population (estimated at 21 million) and a density of 18,000 people per square kilometer, the people of Lagos are quite poor, with very few wealthy inhabitants. Due to their poverty, some people revert to more unorthodox ways of making a living: crime. These crimes include scams, robberies, and fraud. As a consequence of poverty, the inhabitants also experience a lower quality of life due to their incapability to afford any
kind of health care. Overpopulation can be extremely detrimental to the health of a nation.

... genetically modified crops or crops grown with pesticides to their customers without their knowledge. This may concern some consumers, and it is slowly becoming harder to purchase non-GMO products from small agricultural businesses. Therefore, regulations and taxes should be lifted on farming companies in order for these small alternative companies to make an appearance on the market. The government should also establish special offers or programs for the farmers who decide not to sell out their property to suburban developers.
Our world today has many issues that need dealing with. The issues of overpopulation, cultural conflict, and land use will not only effect us currently, but when not addressed, will most certainly effect us in the future. Therefore, we must undertake these challenges before us, in order to create a brighter and better future for us all.
Monsanto scrutinizes neighboring farms, practicing their right to enforce their patent and contract. What they take into account and chose to ignore is that their genetic product is natural and cannot be controlled completely. Monsanto’s patent allows them to prosecute neighboring farms for any concentration of their patented genetic code in their crops, regardless of whether a farmer knowingly involved themselves in infringement or was the victim of natural pollination. Barlett and Steele cite the increasing number of legal cases and settlements as means of pressuring contracted farmers to follow procedure and of allegedly pressuring uncontracted farmers to sign with Monsanto to avoid
As small mobile groups of hunter-gatherers adopted a sedentary lifestyle, they mastered both agriculture and animal domestication. These small settled groups quickly evolved into cities and towns that encompassed the entire globe. Today the estimated population of the world is over 6.2 million people.1 As the population has grown, it has had several deleterious effects on the Earth. These include climate changes, the spread of diseases, declining food production, deforestation, and environment pollution (particularly air pollution). As people have become more conscious of these harmful effects, they have begun to devise strategies to combat this problem. Among the suggested responses include a switch to renewable energy, a call for zero population growth, and adopting sustainable agricultural practices.
Some people believe that immigration in the 1900’s was a good thing, however, they would be wrong. The United States government should have restricted the immigrants around that time. Some reasons are the population, the taking of new jobs and lowering wages, and diseases spreading quickly. These all factored importantly into why they should not have been allowed in.
Garret Hardin’s “Tragedy of the Commons” is an article that identifies the nation’s current problems and predicaments that can’t be resolved through the use of technical solutions. Hardin’s work heavily focuses on overpopulation, a prominent and unceasing issue that significantly distorts and affects the stability of the Earth and the abundance of the planet’s resources. In his article, he mentioned some reasonable and important solutions to overpopulation, but he also explained its downside and how the said solutions may not be ideal and practical. “Tragedy of the Commons” revealed that the human population will continue to flourish and how it will be greatly detrimental to our society unless individuals get the education that they need and
If crops were affected by droughts, disease and insects, having destroyed many acres across America’s Midwest region, the use of Genetically Modified Organisms (GMOs) would not be beneficial in regenerating new crops. Genetically modifying foods (GMOs) “are plants or animals that have been genetically engineered with DNA from bacteria, viruses or other plants and animals that cannot occur in nature or in traditional crossbreeding” (nongmoproject.org). Most research done has concluded no positive benefits in using GMOs. There are serious health risks associated with eating GM foods based on scientific research done around the world. The purpose of GMOs are to increase production of crop yield and reduce pesticide use but research says otherwise. If farmers wanted to continue using GMOs to produce crops, labeling should be mandatory to allow consumers to have a conscious choice whether or not to eat GM food. Through research it has been proven that the use of GMOs to increased production of crops during a time of drought or disease have no benefits, just risks.
Humans have greatly impacted the global environment. Throughout the course of history, human populations have rapidly increased. Especially in Africa, these numbers have reached extraordinary proportions. Out of all the continents in the world, Africa’s population is increasing the most. The type of growth here is exponential. “Overpopulation is a condition when an organisms numbers exceeds the carrying of its ecological niche.” The growth rate of a population is equal to the birth rate minus the death rate. Therefore, for overpopulation to occur, the birth rate must surpass the death rate (Wiley). The current population of Nigeria is estimated to be 155,215,573. Most of the population consists of the younger generation. More specifically, 41% of the population is between the ages of 0-14. 56% of the population is between the ages of 15-64. However, only 3.1% of the population is 65 and over. This age group represents a very small part of the population. (CIA)
Genetically modified (GM) foods have become omnipresent over the past decade. They are a technological breakthrough that allows humans to manipulate and add foreign genes to crops to enhance desired traits, but they have also evolved into a controversial issue, especially for Third World countries. Some people believe that GM foods not only provide larger yields to feed hungry citizens in Third World countries, but they can also be a source of great nutritional value. For example, researchers have developed a strain of golden rice containing high amounts of vitamin A and numerous other vitamins and minerals. Additionally, GM crops are laced with herbicides and pesticides, and therefore reduce the need for chemical consumption. Opponents of GM foods claim that they pose a threat to the health of consumers and that these crops could eventually cross-pollinate in an unregulated fashion or lead to the growth of superweeds and superbugs resistant to the herbicides and pesticides woven into the genetic fiber of the crops. Developed nations should promote research and monitoring from an ethical point of view and financial assistance through philanthropic ventures in order to limit environmental and health risks. They should also make sure that limited cultural displacement will result from the introduction of GM crops and that instead, a better livelihood and well-being through collaboration will emerge. Hence, GM crops should be introduced only provided that the developed nations assume the ethical and financial responsibilities for the environmental, health, and social consequences that attend this new innovation.
In our modern world, there are many problems that plague us, and in the short story “Who Can Replace a Man”, by Brian Aldiss, it is shown that these problems can really affect us in the future. Overpopulation makes the Earth too crowded, and more land has to be cleared, resulting in deforestation. All of our problems relate to each other, and without trying to make our world better in the future our world can be the one in “Who Can Replace a
The human population growth rate is an alarming issue that brings with it irreversible consequences, that will likely effect the way of life for future generations to come. With the serious incline in population statistics comes catastrophic processes such as global warming and deforestation that have major ‘knock on’ ramifications. It’s issues such as these that need to be considered when we think about the growth of the human population, and we must take into account why these issues are occurring. We must also explore the options available to us that may assist in limiting the problems, or eliminating them all together, to provide a better place, not only for us in existence now, but also those who will walk this earth in the future decades and centuries to come.
Human population growth was relatively slow for most of human history. Within the past 500 years, however, the advances made in the industrial, transportation, economic, medical, and agricultural revolutions have helped foster an exponential, "J-shaped" rise in human population (Southwick, Figure 15.1, p. 160). The statistics associated with this type of growth are particularly striking: "Human beings took more than 3 million years to reach a population of 1 billion people...The second billion came in only 130 years, the third billion in 30 years, the fourth billion in 15 years, the fifth billion in 12 years..." (Southwick, p. 159). As human population has grown, there has been simultaneous growth within the industrial sector. Both of these increases have greatly contributed to environmental problems, such as natural resource depletion, ecosystem destruction, and global climate change. Also linked with the increasing human population are many social problems, such as poverty and disease. These issues need to be addressed by policy makers in the near future in order to ensure the survival and sustainability of human life.
...population distribution designed to reduce the rate of rural-urban migration appears to have had limited success in many developing countries. Policies must be directed at altering the rural economy in order to slow the rate of urban sprawl. Broad land use planning and changing of planning standards and governmental procedures would go a long way to reduce many of the problems that face urban populations in the developing areas, especially Africa. Urbanization can cause a lot of problems for a city or even a country. It can cause cities to become overpopulated which are known as mega-cites, and cause problems with living arrangements and finding a job. Urbanization can also cause health problems. Urbanization is supposed to be good for developing countries on the rise but with this rapid growth in Africa, these problems can become a major concern in the future.
...he present century and for sure will be greater in the century we are approaching. More rational use of resources, more effective remedy of pollution and more scientific family planning will surely change the pessimism to optimism in out beautiful world. To conclude, all nations, rich or poor, have great responsibility to challenge the problems that confront our world. Indeed it is a healthy sign that nations meet and discuss policies and strategies, but the most important element in the whole process is the implementation of what has been agreed upon. In order for earth to support us, we have to support it first.
Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives.
So how can we help all these problems that we face as a world? One way could be conducting a family planning system to make it where women can only bear 1 to 2 kids. Individually we as humans can reduce our resources such as less driving and using fewer goods that aren’t a total need. Lastly we can better our education system and increase the graduation rate across the U.S. and other developed countries. Studies have shown that the higher the graduation rate the lower the fertility rate. All of these things can help us cope with overpopulation.
One of the most complex issues in the world today concerns human population. The number of people living off the earth’s resources and stressing its ecosystem has doubled in just forty years. In 1960 there were 3 billion of us; today there are 6 billion. We have no idea what maximum number of people the earth will support. Therefore, the very first question that comes into people’s mind is that are there enough food for all of us in the future? There is no answer for that. Food shortage has become a serious problem among many countries around the world. There are many different reasons why people are starving all over the world. The lack of economic justice and water shortages are just merely two examples out of them all.
