How do we survive the “shrinking” of our planet?
Imagine a world of too many people. How can we deal with this? Can we minimize its effects? How do we take care of the future? The late Carl Sagan played an important role trying to make us understand that our planet is an insignificant Pale Blue Dot, (book) lost in a corner of the Milky Way Galaxy. The awareness, created by his book with the same title, led me to think on the Earth 's land surface which is 149,000,000 km². Well, this number is not going to increase, I thought. As time goes by, more and more people are stepping into our planet which will reach about 11 billion by the year 2100. Although the planet might be able to support this number, what might happen if it is surpassed? Overpopulation is a problem that must be addressed. But, wait! There are people who are convinced that such thing will never happen. Our ingenuity, they say, it is more than able to take care of that situation. Those were the principles and questions that made me embark on this research venture, trying to appeal to a larger discussion, among ecologists/environmentalists, about the pros and cons of what seems to be travelling towards reaching the point of no return.
How many people is too many? The human population has been growing continuously since the end of the Black Death, around the year 1400. The most significant increase has been in the last 50 years, due to advances in medicine which prolong life expectancy. Humans took 150,000
Consider that Earth’s population is projected to rise to 10 billion by the year 2050. The current
No matter how many people do claim overpopulation is not a relevant issue, it very much is because of the simple fact that starvation and pollution are very real and existing issues that are ultimately offset by overpopulation. In an article titled “Overpopulation Is Not the Problem,” author Erle C. Ellis uses the analogy “Like bacteria in a petri dish, our exploding numbers are reaching the limits of a finite planet, with dire consequences,” to argue that overpopulation is not a problem by stating the opposing claim. “We are nothing like bacteria in a petri dish,” Mr. Ellis solemnly asserts, “...these claims demonstrate a profound misunderstanding of the ecology of human systems. The conditions that sustain humanity are not natural and never have been. Since prehistory, human populations have used technologies and engineered ecosystems to sustain
A global population of this size will have a significant impact on the world around us and many factors could impact the human
According to Meder & Windelspecht (2014) the human population was approximately five billion people in the 1650’s, and by the 1850’s is doubled again. Now today we are estimated to have approximately seven billion people
Seven Billion. This number may not be that large when we are applying it to a population of bacteria. But when it comes to people on Earth, the number becomes a little more daunting. In a world full of poverty and environmental destruction, people start to wonder, how many people is too many? This question may seem only newly relevant as we have become more aware of climate change and human effects on the health of our planet, but the truth is this question has been raised for hundreds of years. In fact, in 1789 Thomas Malthus rose awareness of the issues of population growth when he anonymously published his essay. In Thomas Malthus’ An Essay on the Principle of Population, the author discusses why and how a population needs to be checked. Malthus brings up great points for his era but fails to predict one of the main reasons why a population needs to be checked.
Some results of human overpopulation are more serious than others, since some can eventually be fixed. One thing that can not be replaced from overpopulation is if species go extinct. Species are going extinct 1,000 to 10,000 faster than usual. Out of all the 63,837 species worldwide 19,817 are threatened to go extinct. If what is happening continues scientists say that within a few decades half of all plant and animal species on Earth
Stephen Emmott, the author of Ten Billion, states in his book, “that if population levels continue to rise, our grandchildren will see the Earth plunged into an unprecedented environment crisis.” There are many threats to our biosphere, that are directly related to human population increases. Over the past last two decades, the human
According to Southwick, scientists estimate that the optimum global population is no more than 2 billion people. They believe that somewhere between 1 and 2 billion people could be supported in relative prosperity. (161) Compare this with the current gl0bal human population of 6.5 Billion. Clearly, a problem is at hand. Some pessimistic although perhaps realistic scientists even view the current human population growth as a carcinogenic or cancer-like growth with the potential of destroying the global ecosystem. (Southwick161)
When I was in my Biological Evolution class, professor Dr. Matthew Terry started talking about how many people can the Earth support. He said the Earth population has grown dramatically over the past 15 years and it would continue to grow exponentially. For example, when I was born Earth population was about 3 billion people now we have 7 billion people. It got me thinking about why is our population growing significantly and how is this going to affect our habitat. Earth is now overpopulated and there 's have to be some measures. Would it be ethical if we try to control how many babies you can have or try to limit our population? How has technology influenced our population growth? What would be the consequences if the Earth reaches its final capacity? How this is going to affect our environment and other species. These are just some of the burden questions I have about this topic.

There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? The earth can easily support the number of people projected, but only if the right precautions are taken today. Population changes
The world population will increase another 3 billion to 9 billion in 2044 (Figure 1), with the imbalance growing between population numbers and vital life sustaining resources, humans must actively conserve cropland, freshwater, energy, and biological resources.
Over the course of history, many scientist experts have raised the fright and panic about population numbers that only increase every year. According to the Living Planet Report, “the Living Planet Index (LPI), which measures more than 10,000 representative populations of mammals, birds, reptiles, amphibians and fish, has declined by 52 per cent since 1970.” Population sizes of different species in the world has dropped by at least half. Some of these species are the living things that establishes the fabric of the ecosystems which sustain life on Earth. “In the following two centuries, the population increased at an annual growth rate of 6 per 1,000, reaching 2.5 billion by 1950. In the following five decades, it has more than doubled, at a growth rate of 18 per 1,000 to reach more than 6 billion in 2000. The world population will reach 8 billion to 10 billion by the year 2030” (Robbins, 130). Today, we are using and taking so much from our ecosystems and natural processes, we are actually exposing and exploiting our own very existence on Earth. Nature preservation and sustainable ecological development complement each other. They are just as much about protecting the future of humanity – our well-being, economy, food security, and social stability.
Overpopulation is progressively destroying our planet by exhausting our natural resources which leads to a higher cost of living and an increase in our carbon footprint. A person’s carbon footprint can be measured by the total amount of greenhouse gasses a person creates. This is calculated by the C02 (carbon dioxide) and CH4 (methane) created directly and indirectly by means of transportation, energy usage, and resource consumption. We may not see the full effects of overpopulation in our lifetime, but our children will. At the rate that we are growing and the lifestyles we are living, the human race as of right now requires 1.7 planets to sustain life due to overpopulation and resource depletion.
“A crowded society is a restrictive society; an overcrowded society becomes an authoritarian, repressive and murderous society” (Abbey).As resources continue to diminish due to high consumption, what awaits in the future is far from harmonious. It is only until now that government advertisers have found interest in raising consciousness about the issue of overpopulation, but is it too late for the inevitable events that are to come? With the rise of technology that question has become difficult to answer as new advancements continue to do the unexpected and merely the impossible. For instance topics that are now in discussion include cloning of living organisms, colonization in other planets, and creation of virtual worlds. Overpopulation
