Ehrlich and Ehrlich’s 2013 article ‘Can a collapse of the Earth be avoided?’ discusses human society’s choices in the twenty-first century regarding sustainable means of living and the implications this has on future generations (Ehrlich and Ehrlich, 2013). Figure one examines the prediction that the Earth is in grave danger of an environmental and economic collapse due to the irrational and rapid use of valuable resources, over population and consumption and poor technology choices. Evidence has shown that the current population of approximately seven billion people, is above the long term carrying capacity of the Earth, and humans are therefore using more resources than are available, potentially jeopardising the survival of future generations (Ehrlich, Kareiva & Daily, 2012).
The evidence in support of a global collapse is frightening. According to Smith (2010), a collapse is inevitable in an era of shrinking resources, expanding population, a widening gap between the wealthy and the poor, security threats and environmental instability. It has been identified that the addition of one thing, leads to the depletion of another (Ehrlich & Ehrlich, 2013). This can be described as The Human Predicament, whereby the planet is tested to its limits to attempt to hold an unmanageable sum of people, as shown in figure one. The article ‘Can a collapse of the Earth be avoided?’ (Ehrlich & Ehrlich, 2013) identifies that if the entire world used as many resources as the United States did currently, the human race would require an additional four to five more Earth’s to support growing consumption rates.

...and degradation influences greatly ocean acidification which increases susceptibility to infectious diseases. The depletion of scarce resources may in turn lead to resource wars and these wars may very well be the end of the world as human society knows it today (Ehrlich & Ehrlich, 2013). Climate disruption and environmental problems may be the trigger that causes a major global collapse that society will not be able to ‘bounce back’ from.
Earth was previously rich in valuable resources and environmental and economic variability. However, hedonistic values of consumption and self-progression in society in the twenty first century have led to the very real possibility of a global collapse. Through education about sustainable means of living, it is possible to prevent the oncoming breakdown of the planet. However, the question remains – how long can this be prevented?
To begin with, the rise of technology has allowed people an easier way of transportation, but everything comes with a cost, such as greenhouse gases. Cars, power plants, factories, oil sands, clear-cut, to name a few, has all played a factor in the increase of climate change. This can cause the extinction of species. Animals without homes, migration patterns scattered and algae blooms
As time passes, our population continues to increase and multiply; yet, on the other hand, our planet’s resources continue to decrease and deplete. As our population flourishes, human beings also increase their demands and clamor for the Earth’s natural products, yet are unable to sacrifice their surplus of the said resources. Garret Hardin’s work highlighted the reality that humans fail to remember that the Earth is finite and its resources are limited. Hardin’s article revealed that people are unable to fathom that we indeed have a moral obligation to our community and our natural habitat — that we are not our planet’s conquerors but its protectors. We fail to acknowledge and accept that we only have one Earth and that we must protect and treasure it at all costs. Despite all our attempts at annihilating the planet, the Earth will still be unrelenting — it will still continue to be present and powerful. Human beings must recognize that we need this planet more than it needs us and if we persist on being egocentric and covetous, in the end it is us who will
All of these are consequences of one question deep at the heart of the quest for sustainable human existence; the question of the maximum capacity supportable by the planet Earth. As is true of a good deal of the puzzles plaguing our time, little consensus is to be found surrounding this topic.
Resistance arises from mutations that are not under the control of humans, but the evolution of bacteria has been sped along by the overexposure of antibiotics to both people and animals. The number of antibiotic-resistant strains of bacteria in an area is closely related to the frequency that antibiotics that are prescribed (Todar, 2012). Patients often unnecessarily demand antibiotics to treat common colds or simple illnesses that are not caused by bacteria. Instead, these infections are caused by viruses which, unlike bacteria, are unaffected by antibiotics. Incorrect diagnosis can also lead patients to using unnecessary antibiotics, which can sometimes be even more dangerous than otherwise left untreated. Besides the fact that antibiotics kill off beneficial bacteria in the intestines, misuse of antibiotics provides an opportunity ...
In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
Hardin argues how the world only has so many resources and opportunities for agriculture to be expended. Therefore, with enough increase in population, these resources will become extinct. Thus, humans will run out of food and eventually starve to death. As Hardin declares, “a finite world can only support a finite population” (Hardin 98).
Exposure to antimicrobials fundamentally alters microbial ecosystems of humans, animals and the environment, which may lead to the development of antimicrobial resistance.
Although more people are aware of the impacts we have on our environment, there are still people that choose to ignore scientific evidence, or do not fully understand the consequences. Further education and research are critical components in an effort to become more sustainable. Fortunately, younger generations are learning about the need to address environmental issues so that changes can be made to ensure our way of life is sustainable.
“We are consuming the Earth’s natural resources beyond its sustainable capacity of renewal” said by Herman Daly, Beyond Growth, Boston 1996, 61[1] .
One of the major effects of the huge population increase has been the depletion of natural resources and the destruction of ecosystems. In the 1960's, theorist Paul Ehrlich predicted that, given the skyrocketing figures of human population, the amount of food produced would not grow at a fast enough rate for human survival (Professor Carr Everbach, personal communication). He predicted mass starvation and death by the year 2000 as the result of uncontrolled population growth. Clearly, this did not occur. Ehrlich did not foresee the advancements ma...
...dearly-held, unconscious collective assumptions may impede our chances for survival. Or, as Poliakoff, et. al., noted, “fundamental changes in technology are adopted… only when they provide real advantage” (810). Are human beings inherently selfish, or are they capable of rising above that? Will we use this power we have developed to help ourselves, or to attempt to help the world? “Why can’t we achieve a better balance between people, resources, and the environment? … The complete answers to these questions lie deeply within the complex realms of science, philosophy, religion, economics, and politics.” (170). The answers may be complicated. The truth is, industrialization has changed our relationship to the environment. It has enabled us to hurt it far more than any other species, but it has also given us the ability to help. The power of choice now lies with us.
Though several people see large rapidly growing populations in developing regions as the primary culprit in environmental decline, we need to focus on the costly environmental outcomes of overconsumption among the gradually increasing populations of the developed nations. These differing emphases naturally point to fundamentally different solutions: slow population increase in less-developed nations or change destructive consumption and production patterns in the more-developed nations. This debate, however, assumes a one-step answer to the complex problems created by population pressures on the environment. Both population size and consumption ...
Humans have become a threat to our own way of life by consuming more resources than needed, blind to the consequences that we may face in the future. As of 2016 the world population is at 7.4 billion and it is estimated to be at 11.2 billion by the year 2100. However 10 billion is the maximum population that can be sustained in terms of food security, only one of the many factors to global sustainability. Due to the fact that human consumption exceeds the amount of resources available, the United Nations “recognizes that eradicating poverty is the greatest global challenge” in A/RES/70/1. Sustainable development is not only required to fulfill the necessities of the present but to guarantee the capability for future generations to satisfy theirs.
Sustainability Revolution: Earth, the planet we call home, is a complex system made of interdependent parts and pieces of life that are constantly changing. Earth’s planetary system has maintained a balance of dynamic equilibrium—it has been sustainable— since its beginnings about 4.5 billion years ago. This balance, however, has been progressively disrupted by us—humans— especially during the last few decades. Mother Nature has provided us with natural resources and the habitat for all species to sustain life on our planet. Since the industrial revolution, we have maintained a belief that these resources are infinite, and that economic growth and our attempts to improve our standards of living can continue forever. All forms of human economic
The reduction of the Earth's resources has been closely linked to the rise in human population. For many thousands of years people lived in relative harmony with their surroundings. Population sizes were small, and life-supporting tools were simple. Most of the energy needed for work was provided by the worker and animals. Since about 1650, however, the human population has increased dramatically. The problems of overcrowding multiply as an ever-increasing number of people are added to the world's population each year.
