David M. Lodge's essay “'It's the Water, Stupid!'” asserts that the world needs to find a
win-win-win situation and a balance in the use of water resources for environmental, public health, and commerce problems in order to ensure the safety of human beings and halt dramatic changes to aquatic species and their environments. Lodge develops his point with environmental and public health statistics as well as numerous references that show the relationship between the necessity of water resources to live and our environmental problems. Lodge discusses the world problems of water resources and the needed better management of them in order to spread awareness about the topic as it is an overlooked, global problem. Lodge's essay is written in BioScience which is read by the well educated, but his essay seems to be targeted at a wider audience considering the weight of the issue and the easy readability of the piece.
Lodge is a professor of biological sciences and director of the Center for Aquatic Conservation at the University of Notre Dame. His research focuses on conversational biology and aquatic invasive species. Lodge also administrates a number of committees and organizations that concentrate on invasive species including the direction of the NSF-funded ISIS (Integrated Systems for Invasive Species) project (“David M. Lodge”). This article appeared in the January issue of BioScience, which is a heavily edited and peer reviewed journal of research and essays on biology. Despite some of the complexity of the articles in BioScience, Lodge's thesis is significant to humanity so the article was written for a larger audience. Lodge covers three important topics relative to his thesis that are broad enough for anyone to understand,...

...his knowledge, he executes his ideas on paper very well with examples and devices, but his writing seemed to stutter at moments with writing style inconsistencies. Nonetheless, his essay is basic enough and intuitive that it is understandable by wide range of people. His sources on the subject are narrow and only supportive of his thesis, but common sense generally agrees that harming ourselves and/or the environment is not a good thing, even though we can't see it sometimes because we are blinded by greed. I found his piece insightful and interesting, but can also take from his writing style and ability because he has written a strong essay.

“How can you buy or sell the sky-the warmth of the land? The idea is strange to us. Yet we do not own the freshness of air or the sparkle of the water. How can you buy them from us? We will decide in our time” (Chief Seattle: 1855). In the Documentary “Flow – for the love of water” it visualizes the global crisis we face on Mother’s Earth as it pertains to the diminishing of fresh water. The Documentary portrays along with the help of experts that this global crises is affecting each and every one of us in today’s society including animals. The film shows us that water is constantly being wasted, polluted, and privatized by big co operations. Prime examples of these greedy companies were mentioned in the film such as Nestle, Thames, Suez, Vivendi, Coca Cola and Pepsi.

David Foster Wallace, in his commencement speech, "This is Water," argues that a liberal arts education is not about accumulating knowledge but about developing the ability to consciously choose what to think about and how to interpret experiences. Wallace expresses his thoughts through humor, personal stories, and philosophical ideas to convince graduates of the importance of this skill. While his unconventional approach might raise eyebrows initially, his use of relatable situations and genuine concern for his audience strengthens his argument. One of Wallace's most effective techniques is his use of relatable anecdotes. He starts by deconstructing the typical commencement speech, immediately establishing a connection with the audience by acknowledging the

Some families in Afghanistan need water more than anything so they have to send their own kids early in the morning in the cold to get water but they can't because they are too weak . The video “The Plight of Afghanistan’s Child Water Carriers” by Zarif Nazar and the text “The Plight of Afghanistan’s Child Water Carriers” by Sayead Jan Sabwoon both discuss an issue surrounding children who live in Afghanistan. These Children cannot go to school because they have to help their families survive and get water that the family needs.

Freshwater in the world makes up only a small portion of 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. Many of these in later years shall need to be addressed as tension rises:
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, 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. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.

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.
In many parts of the world the unfavourable results of man’s long-term - often unreasonable - activities, have now been discovered. This concerns both the direct use of water resources and also the surface transformations that have taken place in many river catchments. To a large extent this has been due to a drastic increase in global water withdrawal since the 1950s. In turn, this increase was caused by the scientific and technological revolution which permitted the intense development in production capabilities in all spheres of the world economy. Compared with previous decades, annual water withdrawal during 19.51-60 increased fourfold. This occurred because of the dramatic expansion in irrigated areas, the growth in industrial and heat and power engineering water consumption, and the intensive construction of reservoirs in all continents. All over the world during the last 25-30 years there has been a massive anthropogenic change in the hydrological cycle of rivers and lakes, affecting their water quality, their potential as water resources and the global water budget. The extent of water resources, their spatial and temporal distribution, are determined not only by natural climate variations as previously, but now also by man’s economic activities. In many parts of the world water resources have become so depleted and much contaminated that they are already unable to meet the ever increasing demands made on them. This has become the main factor impeding economic development and population
