From the beginning of time, the earth has provided its inhabitants with everything needed to sustain life at its most basic level. For instance, the ratio of land to fresh water as well as Earth’s natural cycles provided enough resources for animals to survive. Unfortunately, as the human population grew, the previously abundant natural resources started to become limited. In fact, engineers have recently been tasked with discovering new methods of harnessing energy, harvesting food, and collecting fresh water because the population is quickly depleting traditional techniques. Not only is the sheer number of people on Earth using up all of its natural resources, but humans’ modern desires are furthering the destruction of Earth. In developed …show more content…
This tendency of developed countries to exceed the minimum standard of living combined with the increasing population is steadily depleting nature’s offerings. The nitrogen cycle, the carbon cycle, and the water cycle have been disrupted as a result of human activity which is destroying the cycle of life.
The nitrogen cycle is the natural process through which nitrogen travels “from the nonliving, such as the atmosphere, soil or water, to the living, whether plants or animals” (Brown University). Unfortunately, humans are disrupting this cycle by changing the amount of nitrogen found in the biosphere. The main factor affecting the nitrogen cycle is pollution, specifically fossil fuel combustion. When fossil fuels such as coal are burned, nitric oxides are released into the air. Subsequently, the oxides combine with other elements to form smog and acid rain. Scientists are confident that the use of fossil fuels are the main contributor to the change in the nitrogen cycle because it was found that the greatest change in nitrogen isotope ratios occurred following a rapid increase in fossil fuel emissions.

Humans often take the water cycle for granted and assume that fresh water will always be available for drinking, cooking, farming, etc. Unfortunately, the ways in which society uses water is contributing to the reduction in fresh water available for human use. First of all, the use of hydroelectric power, though a clean source of energy, is negatively affecting the ecosystems in which the plant is stationed. The waterway must be dammed in order to maximize the potential energy of the water, but this often affects the function of the waterway upstream and downstream. For example, the build-up of water above the dam may create a lake where silt can build up while a lack of water below the dam eliminates habitats. Moreover, plants and aquatic animals that previously inhabited the waterway “may find themselves with too much or too little water, and migrating fish cannot get through the dams” (Humans and the water cycle). Not only does hydroelectricity disrupt the water cycle, but irrigation does as well. “Irrigation is the artificial watering of land that does not get enough water through rainfall” (Humans and the water cycle). Most countries that use irrigation have dry land or they require more water to grow more plants for their increasing population. The issue with irrigation is that it removes relatively clean water from its natural source and essentially pollutes it. The fertilizer in
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
Water is the foundational basis of life on Earth. Ecosystems, society and humans are completely dependent on it, and as the world population continues to grow, there will be more mouths to feed, and those people will need water to continue their daily lives. However, shortages and poor management leads to the destruction of natural habitats and human suffering. Desertification of land in China is ever-increasing, turning green, lush land into desert. However, this is due mainly in part, because of human activity, and global warming (Wang, Yang, Dong, & Zhang, 2009). The United States could experience a crisis similarly to China’s, but for now they have averted such a catastrophe, because of heavy regulation of water. Though there are water shortages in many parts of the world, it is unwise to export water from the Great Lakes to those regions. Two major reasons why diverting the Great Lakes is a terrible idea, one: it allows for waters wars to start on the basis of who is allowed to access it and for commodification purposes. Two, diverting water on such large scales could have cataclysmic effects on the local residents as well as the environment.
The carbon cycle describes the movement of carbon as it is recycled and reused throughout the biosphere. Due to water, land and air pollution that humans cause, organisms in the ecosystem are harmed, thus decreasing the amount of carbon that is released into the atmosphere. If less carbon is released, photosynthesis in plants would be disrupted too because they need carbon dioxide, chlorophyll, water and sunli...
Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural ...
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.
We often hear the saying that water is the source of life so how can mankind waste this precious source that God has given us. A fine example was mentioned in the film about India’s new green agricultural system where 30 times more water is been use than the actual amount required. It is really hard to see how these farmers are spitefully wasting water when it is really needed in the neighboring communities. This goes to show that people only do things to benefit themselves not considering the needs of other people. Not only is water being wasted in developing countries but there is also water wastage in developed countries we often take our water sources for granted here in the US such as not turning off the pipes when brushing our teeth or washing our hands and the list goes on. Water conservation is the key to saving our planet because soon it will become extinct to us human beings.
Living thing need air to breath. Air unseen and untouchable. Air are consist of nitrogen, oxygen, carbon dioxide and other gaseous. Nitrogen is an important element for the living organisms to live and to form the complex organic molecules such as proteins and amino acids. However, most of the living organisms such as plants can only use the nitrogen which already in compound form because the pure nitrogen is inactive and the strong triple bond between its atoms are difficult to break. In order to produce nitrogen that is in compound form, it has to undergo a process known as nitrogen cycle. There are five important processes to create the nitrogen cycle which are nitrogen fixation, nitrification, assimilation, ammonification and denitrification
The earth’s population is ever increasing; it is only a matter of time before there are not enough resources to support life on the planet and the population begins to die off due to lack of food, water, and other resources. With our current population increase rates the population will double within the next century. “Indeed, the world population did double in thirty-seven years from 1950 to 1987.'; (Ehrlich, 1990) The problem with overpopulation is that even if we all reduce our impact on the environment, when the population doubles, so will the total impact on the earth will be doubled.
It includes the water found in lakes, reservoirs, and groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today.
Water is on of the most precious natural resources that exist on our planet. “It is delivered from the atmosphere in the form of rain, snow, hail, fog, and condensation and returns to the atmosphere by evaporation and transpiration” (Hannigan 1969). Although many of us love activities that have to do with water, we disregard it and pollute out rivers, lakes and oceans. Slowly but surely we are going to harm out planet till no return. Protecting and conserving nature will secure a better future. 71% of earth is covered with oceans. Sounds like a lot right? Imagine ...
The abundance of natural resources used to be generally assumed, but in recent years, questions are beginning to be raised, including the availability of fuel and other minerals. Decreasing supplies of natural resources and increasing world population growth has added pressure to the world's search for energy. Humans have harmed nature by overusing, wasting, and abusing its supply of natural resources.
People don’t appreciated the many advantages that comes with having clean potable water to use, taking it for granted. A lot of clean useful water is wasted by humans all the time that people don’t care about saving water because they have easy access to it. Clean and safe drinkable water resources are getting scarce as the population grows. The world is facing many problems, but the most important needed to survive, is water. Water is getting low in many countries, therefore habitants are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages; meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands. Water shortage affects the agricultural sector, so as a consequence the price for production
The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
Freshwater in the world makes up only a small portion of the water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only 1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes.
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.
