How water fits into sustainabilityWater SupplyWater is slowly becoming the next global environmental problem, as it is one of the most pressing resource issues of this century. According to the University of Arizona's College of Agriculture and Life Sciences, there has been a six-fold increase in water use, which is almost triple the increase in population, since 1900. This means that even in proportion with the increasing population, water usage has risen. The world population is currently around six billion, and the United Nations predicts that it will be nine billion by 2050. Water consumption will only continue to increase as agricultural, industrial, and domestic demands also increase. The World Bank reports that 80 countries have water shortages and that 40 percent of the world does not have access to clean water. Amidst this water shortage, pollution, industrial farming, and raw sewage dumps are making matters worse by ruining water quality.Climate ChangeAccording to the University of Arizona, climate change also contributes to this water problem: "With higher temperatures and more rapid melting of winter snowpacks, less water supplies will be available to farms and cities during summer months when demand is high." Climate change is bringing hotter and drier summers, in addition to more development on wetland sites, which will deplete water stores that rely on underground and reservoir water [Goldsmith]. Water conservation is a must if we want to stand a chance against increasing population and needs and climate change.Back to Top Tap water vs. bottled waterWhy is bottled water bad for the environment?The process of making bottled water has a great cost. According to the Earth Policy Institute, $100 billion is spent on bottled water annually, but this money could be spent on water treatment and sanitation systems, in addition to other projects geared towards conserving and making the best use of our water supply. Beyond monetary costs, producing and packaging and shipping bottled water also hurt the environment.Packaging bottled water is not resource-effective, nor is it environmentally friendly. Most bottled water uses polyethylene terephthalate - PET plastic. PET plastic is "derived from crude oil," and making these plastic water bottles "requires more than 17 million barrels of oil annually, enough to fuel more than 1 million U.S. cars for a year" [Arnold and Larsen].Transporting bottled water also burns large amounts of fossil fuels, whereas tap water is energy-efficient. According to the Earth Policy Institute, "nearly a quarter of all bottled water crosses national borders to reach consumers, transported by boat, train, and truck." The energy that it takes for bottled water to travel from one nation to another adds to the resources that each bottle of water spends, and these resources can be allocated elsewhere. Moreover, although PET plastic is recyclable, consumers purchase and drink bottled water but do not recycle the bottles. According to the Container Recycling Institute, 86% of plastic water bottles used in the United States become garbage or litter. The US alone sends 2 million tons of PET plastic from bottled water to landfills each year [Reynolds]. Once it reaches the landfill, this plastic creates "toxic byproducts such as chlorine gas and ash containing heavy metals," and a bottle can take up to 1,000 years to biodegrade [Arnold and Larsen]. In 2005, according to Worldwatch, the recycling rate for PET was only 23.1% in the US, compared to 80% in Switzerland. This recycling rate can and should be 100%. Bottled water is also contributing to water shortages because the rapid growth in the bottled water industry is resulting in concentrated water extraction. Communities with bottling plants, such as Texas and the Great Lakes region, are experiencing water shortage [Arnold and Larsen]. The ecosystems in these areas are damaged, and people like farmers and fishers are negatively impacted by the consequent water shortage. Back to Top
The difference between tap and bottled waterMany people believe that bottled water is cleaner, safer, and healthier than tap water. However, this is not necessarily true. In fact, tap water is probably the cleaner, safer, and healthier choice. Tap water is regulated by the Environmental Protection Agency (EPA), and bottled water is regulated by the US Food and Drug Administration (FDA). According to the New York Times, tap water is more strictly monitored and regulated, and in 2004, tap water in New York City was tested 430,600 times. Furthermore, bottled water is much more expensive, as it can be 240 to 10,000 times more costly than tap water [Reynolds]. Also, in developed countries, bottled water is regulated with lower standards than tap water. Below is a table outlining the differences between the two:3 reasons why tap water is better:
