As the differences between men and women in Table 4 shows, the latter have a substantial and significantly higher tap water consciousness ( p < .001), a difference that primarily relates to the affectional dimension ( p < .05). As expected, significant differences were also found in the educational background of respondents. Respondents with a low education show a significantly lower overall TWA ( p < .05). This lower awareness score, however, can solely be explained by a significant lower cognitive tap water consciousness ( p < .001), and does not relate to the affective nor to the behaviour dimension. By contrast, citizens with a high education show a significantly higher overall TWA. This difference relates most strongly to a significantly higher cognitive TWA ( p < .001) and to a lesser extent to a significantly higher affectional TWA. Strikingly, the differences between the different age groups are negligible. Additional TWA scores for demographic variables are presented in S3 Appendix .
From a modern segmentation perspective, and an analysis on the possible differences on the basis of the four earlier introduced customer perspectives on drinking water as presented in Table 1 , we find that the respondents with the ‘aware & committed’ perspective show a significantly higher overall TWA ( p < .001). On the contrary, respondents with the ‘down to earth & confident’ perspective show a significantly lower overall tap water consciousness ( p < .001). Indeed, and in support of the work of Brouwer et al. [ 25 ], this study shows that respondents with the ‘aware & committed’ perspective highly value sustainable behaviour, including, for instance, water-saving efforts, whereas respondents with the ‘down to earth & confident’ perspective are characterized by great confidence in the responsibility of drinking water utilities, along with the desire not to be bothered about drinking water. When zooming in further on the results depicted in Table 4 , it can be observed that not only the total awareness scores reach this significance, but also all three separate awareness dimensions. Indeed, respondents with the ‘aware & committed’ perspective show a significantly higher cognitive ( p < .05), affective ( p < .001), and behavioural awareness ( p < .01). By contrast, respondents with the ‘down to earth & confident’ perspective only show a highly significantly lower affectional awareness ( t = -11.961, p < .001). Interestingly, respondents with the ‘down to earth & confident’ perspective do not show a lower cognitive TWA. On the contrary, although respondents with the ‘aware & committed’ perspective show the highest score, respondents with the ‘down to earth & confident’ perspective show a slightly higher cognitive tap water consciousness. This is a telling result, for it suggests that respondents with the ‘down to earth & confident’ perspective show a relative low behavioural TWA. Not because they have less water knowledge, inquiry or understanding than respondents with the other perspectives, but simply because they care less. A partly opposite result can be seen in respondents with the ’quality & health concerned’ perspective, characterised by their focus on personal preferences and needs, especially regarding their own health. These customers show a lower cognitive tap water consciousness. However, at the same time they show a higher affectional tap water consciousness.
Table 5 depicts the scores of Dutch drinking water customers for the nine different awareness components of our three-by-three dimensioned TWA assessment framework, organised around the principles head (cognition), heart (affection), and hands (behaviour), and the substantive themes water quality, water quantity and system. As explained, the scores along the layout of the dimensions shows that the average scores are highest for behavioural and affective TWA, and relatively low for cognitive TWA. As shown in S3 Appendix , from a thematic point of view, we find that people’s water quality awareness is, with an average score of 48.2%, relatively low, followed by water quantity with an average score of 54.7%. People’s water system awareness, relating to awareness of tap water in its broader context, scores relatively best with an average score of 57.9%.

Looking at the individual awareness components as detailed in Tables Tables5 5 and and6, 6 , we find a rather wide variation in maximum awareness scores, ranging from 34.2% for component (II) water consumption knowledge to 70.7% for component (VIII) curtailment & efficiency behaviour. Indeed, based on the survey answers on the questions about the water use of a conventional shower head and the societal average daily water consumption, it appears that customers generally have “cognitive gaps” in their understanding of water consumption knowledge. For one illustration, on the open question of estimating the average daily water consumption of one person in the Netherlands, only 5% was able to give the correct answer of 120 litres (with a margin of ten litres). Most citizens, however, estimate this consumption below 50 litres (51%), between 91–110 litres (10%), or between 131–150 litres per day (6%). On the other end, we also find a group of respondents (16%) estimating that this average daily consumption of water is more than 191 litres a day. We found that respondents with a high level of education have a higher tap water consumption knowledge. Water consumption knowledge is the only water awareness component without a significant correlation with one of the four water customer perspectives.

1 The average curtailment and efficiency behaviour score of respondents with ‘aware & committed’ perspective is higher, though not significant, as compared to respondents with the ‘egalitarian & solidary’ perspective. This can be explained by the difference in STD. With an average of 5.656, the former segment has a STD of 0.35521, whereas the latter segment has a STD of 0.35047.
The component with the highest awareness scores relates to (VIII) curtailment & efficiency behaviour , assessed by asking people about their daily tooth brushing water-use pattern, their water-saving appliances installed in-house and in theory, but as explained above disregarded, the volume record on their latest water bill. The high score can mainly be explained by the tap water use while tooth brushing. 76.4% of the respondents state to always close the tap while brushing their teeth and another 15.8% almost always does so. Moreover, people also stated to have (several) water saving appliances installed in their homes. 54.6% has a water saving showerhead and 59.4% has a water saving washing machine. Women show significant and substantial higher levels of curtailment & efficiency behaviour than men ( p < .001).
A third awareness component worth singling out is component (IV) water quality perception . Not because this component has resulted necessary in deviant scores but because, next to quality perception and the question on the frequency of thinking about the quality of water, it assessed to what extent respondents perceive clean tap water as something that can be taken for granted. A small majority of 50.6% of the respondents ’fully agrees’ and a further 37.4% ’agrees’ with the statement that clean tap water is something obvious. The percentage of respondents that instead do not regard clean tap water as something obvious, but instead for instance as rather special, is very small. Only 4.9% does not agree with the former statement; 0.8% does not agree at all. Overall, we find that again women score higher on water quality perception than men do. Also respondents with a high education have an overall slightly higher water quality perception. Again the differences are bigger when looking at the different customer perspectives. Respondents with the ‘aware & committed’ perspective show a significantly higher water quality perception ( p < .001). On the other end, customers classified according to the ‘down to earth & confident’ ( p < .001) and to a lesser extent also the ‘quality & health concerned’ perspective, have a significantly lower water quality perception. The reason why these two groups score low on this aspect, however, differs per perspective. Respondents with the ‘down to earth & confident’ perspective score especially low because they overwhelmingly consider it self-evident that clean water runs out of the tap. Respondents with the ‘quality & health concerned’ perspective, on the other hand, score particularly low because they—unjustly—relatively often have the idea that the quality of their tap is uncertain.
Overall it is remarkable that women score higher than men on all components, albeit not always significantly. The individual scores for the head (cognitive), heart (affective), and hands (behavioural) dimension are presented in Tables Tables5 5 and and6. 6 . Fig 1 illustrates these different scores into a TWA profile. The strongest difference between women and men relates to the tap water source protection (IX) scores (84.5% versus 49.2%, t = 20.161, p < .001), in our framework assessed by asking respondents about their medicine and chemical products disposal behaviour.
Next to the gender difference, the biggest differences relate to the different perspectives. Indeed, respondents with the ‘aware & committed’ perspective have a significantly higher TWA ( p < .001). This finding is reflected in Table 6 , depicting that this segment shows a higher water quality comprehension (I) and water quality perception (IV). Furthermore, the results of this study show that respondents with the ‘aware & committed’ perspective care significantly more for water, and depict a higher caring for water (V) and sense of responsibility (VI) score, and have significantly higher levels of quality-driven behaviour (VII). The segment with relative the lowest TWA are respondents with the ‘down to earth & confident’ perspective. Table 6 shows that this particularly relates to a lower affectional scores. Indeed, we find that these customers not only have a significantly lower water quality perception (VI), but also care significantly less for water (v), and feel a significantly lower sense of responsibility (for all three, p < .001). As indicated in the above, this result is not related to a lower cognitive score, if only because this very segments shows a significantly higher water system understanding (III; p < .001).
As already noted, a partly opposite result can be seen in respondents with the ’quality & health concerned’ perspective. These customers show a lower water system understanding (III). At the same time, they tend to care more for water (V), and alike have a higher sense of responsibility (VI). The solely affectional component where respondents with the ’quality & health concerned’ perspective show a lower score is tap water quality perception (IV). This finding can, however, be fully explained by the elemental position of the profile itself, in which care for and concern about the quality of water in relation to their health are central [ 25 ]. Finally, we find that respondents with the ‘egalitarian & solidary’ perspective have a significant higher score on two components of the behavioural dimension, i.e. curtailment & efficiency behaviour (VIII) and tap water source protection (IX). In addition, they also show significantly more care for water, but this relates more to the very low score of respondents with the ‘down to earth & confident’ perspective than to a remarkably high score for ‘egalitarian & solidary’ customers.
Looking at the differences between respondents with different educational backgrounds, depicted in Table 6 , especially the behavioural component is noteworthy. Here we find that respondents with a low level education have significantly lower levels of quality-driven behaviour ( p < .01) but substantially higher levels of tap water source protection (IX; p < .001). Interestingly, we find the reversed patterns when looking at respondents with a high education. Indeed, they show significantly higher levels of quality-driven behaviour (VII; p < .001) and significantly lower levels of tap water source protection (IX; p < .001). This contradiction is also observed in other studies [ 47 , 66 ].
This study shows that a complex and multifaceted concept such as TWA, which seems to have become a catch-all term, can be well conceptualised and operationalised into a practicable empirically-based assessment framework. Consistent with the organizing principle of head, heart, and hands, this three-by-three dimensioned assessment framework distinguishes between cognitive, affective and behavioural awareness of tap water. In addition to this threefold conceptualisation, a second distinction was made based on the substantive characteristics of tap water: water quality, water quantity and water system.
In addressing the research aim to conceptualise, operationalise and assess TWA, this study has presented a TWA framework consisting of three dimensions; nine components; and 24 questions, which subsequently has been empirically tested in a large-scale survey in the Netherlands. Overall, this assessment has demonstrated that, as previously observed by the OECD [ 12 ], TWA in the Netherlands shows ample room for improvement. This is especially the case for the cognitive dimension of TWA, relating to one’s water quality comprehension, consumption knowledge, and system understanding. The scores for both affective and behavioural tap water awareness are slightly higher, with the components ’tap water source protection’ and ’curtailment & efficiency behaviour’ as positive outliers.
The tap water assessment analysis becomes even more interesting when we break down the scores for the different dimensions and components to different types of customers. It is striking that women score higher than men on most aspects of TWA, whereas other socio-demographic variables were not or hardly distinctive. The former observation is in coherence with previous studies demonstrating that women consume less tap water as compared to men [ 69 , 70 ] as well as with studies suggesting that, on average, women in the Netherlands make more sustainable behavioural choices [ 71 ]. Segmentation based on the drinking water customer perspectives show, as previously reported by, for instance, Brouwer et al. [ 38 ] and Koop et al. [ 72 ], clear differences all along the line. Customers with the ‘aware & committed’ perspective have significantly higher, and customers holding a ‘down to earth & confident’ perspective significantly lower TWA scores.
The combined insight into the different customer perspectives and the proposed assessment framework may facilitate both the effective implementation and evaluation of future TWA raising campaigns. After all, for policymakers it is important to acknowledge that TWA consists of more than caring for water alone, and that e.g. the tap water knowledge people may have not always aligns with their conservation efforts or quality protecting behaviour. Moreover, it is important to appreciate that techniques that may work well for customers with, for instance, the ’aware & committed’ perspective may generate an entirely different effect on customers holding a ‘quality & health concerned’ perspective.
Beyond this study’s primary objective, the rich survey results provide ample opportunity to explore underlying patterns and key factors that characterise Dutch TWA. As such, both a Principle Component Analysis (PCA) and a multiple regression analysis have been conducted. The PCA has identified two main components explaining 21.2% of the variance (see S4 Appendix ). Component 1 represents a pattern where respondents think relatively often about the quality (question IV.3), origin (question VI.1) and own consumption of drinking water (question V.3), experience tap water services as special (question V.2), have water-saving household devices (question VIII.2), want to save water (question V.1) and dispose leftover medicines, paint and pesticides in an environmentally friendly manner (question IX.1 and IX.2). This coherence in the affection and behaviour related to the substantive elements water quantity and system suggest ‘a level of personal responsibility to preserve clean and sufficient drinking water’. Interestingly, the perception and behaviour of water quantity and systemic responsibilities seem therefore intertwined irrespective of people’s knowledge about the topic. Component 2 consisting of knowledgeability of the responsibilities of drinking water utilities (high score question III.3), perception that drinking water is safe (high score question IV.1), and low consumption of bottled water (high score question IV.2) may represent ‘a trust in water services’. Plotting these two key components shows a clear distinction between head, heart and hands dimensions ( Fig 2 ).
Overall we can observe that the level of personal responsibility for preserving clean and sufficient drinking water is positively related to heart and to a lesser extent with hands. Interestingly, the level of knowledge is only positively related with the trust in water services. The more people know about drinking water, the higher their trust in these services. However, knowledge has no positive or negative impact on the level of personal responsibility people experience to preserve clean and sufficient drinking water. From this observation, it may be reasoned that campaigns that only focus on enhancing people’s knowledge may improve people’s trust in water services, but generate little or no impact on the level of personal responsibility to help preserve this service by for instance reducing their water use or by more environmentally-considered disposal of their leftover medicines, paint or pesticides.
A multiple regression analysis was applied with the aim of exploring which questions are most predictive for the overall score. As a result, the following questions turned out to be the most predictive for the overall TWA score: questions on (i) the disposal of leftover medicines (question IX.1); (ii) the consumption of bottled water (question VII.2); (iii) the knowledge that there is no chlorinate in the Dutch drinking water (question I.2); (iv) the knowledge that quality requirements are more stringent for tap water than for bottled water (question I.3), and (v) the knowledge on the origin of tap water (question III.1). A key observation of these most predictive questions is that the quality requirements and measures taken to produce drinking water are relatively unknown, also in relation to bottled water (low scores on questions I.3, I.2), whilst the related behaviour of drinking bottled water at home still occurs regularly (question VII.2). This misconception on bottled water seems to be particularly telling in understanding someone’s tap water awareness. Further details of the multiple regression analysis are provided in S4 Appendix .
Future research is needed to determine which strategies can best be used to increase the TWA of different types of customers. These strategies may combine several TWA dimensions. For example, the roll-out of digital water meters in combination with frequent user feedback in terms of both litres and costs may appeal to both the cognitive and the behavioural dimension [ 72 , 73 ]. For both the affective and cognitive TWA dimension, the implementation of citizen science projects in the field of tap water could cause customers to experience that the self-evidence of constant clean tap water may, in fact, be rather special [ 74 ]. Finally, the use of smart behavioural techniques such as the use of emotional shortcuts and nudging [ 47 ] may form promising strategies, appealing both the affective and behavioural dimension of awareness. In addition, it is interesting to work towards a comparable—and eventually integrated assessment framework—for also surface and groundwater. Additional challenges that need to be addressed in the future relate to the fact that the current study and the framework is not without limitations. First, while the gap between intentional and actual behaviour is acknowledged, the present study builds on self-reported behaviour. Second, relatively many respondents did not report their actual water consumption by checking the volume record on their latest water bill, impeding an analysis of actual consumption patterns in relation behavioural intentions, i.e. the so-called “intention-behaviour gap” [ 24 , 75 ]. Third, the context in which this research was conducted—that is, a small and wealthy country marked by its high quality of tap water and publicly owned utilities—might have influenced our results. After all, Koop et al. [ 76 ] suggest that local contextual factors, such as the different risks, probabilities and impacts, past experiences, existing institutions and policies may considerably impact people’s water awareness. Future studies could constructively build on the current research by (a) assessing actual behaviour, (b) with consent of respondents, coupling survey results to actual user data provided by utilities, and (c) applying the assessment framework in other contexts and cultures.

In this lesson today, I will discuss how exactly you can write short essays on the important topic ‘Water.’ There will be three sets of essays in this following session, each within different word limits.
Every living being on the earth needs some basic things for its survival. It includes food, water, shelter, and money as well for humans. Water is by far the principal need of living beings. About two-third part of the earth is covered with water.
Water is available in several forms on earth. Some amount is frozen in glaciers, while the larger amount of water is salty. Fresh water on earth is very little. We need water for every purpose. Drinking, cooking, bathing, washing are the basic needs, while water is also used by bigger industries to run their machines. Water is an important source of electricity. So, being the most valuable resource water must never be wasted.
Water is the most significant resource among everything that humans and animals can receive. Water helps a living being to live for longer days, even when food is scarce. It is one of the most beautiful gifts of nature. Water has enormous benefits and is the life of the earth. Its medicinal properties cure several ailments in our bodies. Without it, we cannot imagine living a second on earth. The world will be a huge desert if the water on earth is destroyed.
Our earth is unique in its creation. About two-third part of it is covered with water, while the rest of it is land. If we take a deeper study, then a major part of the water is either frozen as glaciers or is present in the oceans as saltwater. The reserve of fresh water on earth is a limited amount. It can exhaust at any moment. Hence we must spend water wisely. We need water for drinking, bathing, washing clothes and utensils, cooking, cultivating, etc.
Big industries require lots of water to run their machines. Today due to the scarcity of coal, hydroelectricity is the new way of generating electrical power. This process requires huge amounts of water. In several ways, water is our saviour. It is the beauty of nature as a wonderful waterfall or a stream, and also the help to a thirsty person.
Water is the basic strength behind all life forces on earth. It is the necessity of every life and is the biggest shelter for us to survive. If there is no water suddenly on earth, then it will only be a lifeless planet filled with dust and stone.
The green earth will become a long stretch of a desert without this component. Water forms about two-thirds of the earth, while only one-third is given for the land. Yet how much greater the amount of water on earth be, the availability of fresh water on earth is the minimum.
A large amount of water is left unused. It is either frozen as glaciers or is present as salty ocean water. This water cannot be applied for regular usage. So we must understand the wise utilization of water. It is a scanty but most important resource. So only its proper utilization can make it sufficient.
Water is the source of all activities in our lives. From the olden days, human beings have always tried to live near water bodies. Because those places are fertile for cultivation. A vast desert-like Egypt also survives because of the river Nile. The Ganges in India is not only a water body but one of the most sacred rivers in the world. The most important use of water is in agriculture.
Every plant needs it to grow. If crops do not receive adequate water, then they will be stunted. We use water for drinking, cooking, bathing, washing. A living body needs lots of water intake. Insufficient water intake can result in lots of ailments. Water is beneficial for this medical property. Besides these, all industries need water for producing electricity and running the turbines. Water is the potential of civilization. A civilization operates because of the availability of water
But at present, we are observing the pollution of water bodies. It is dangerous for all living beings to survive if all water sources are contaminated. Polluted water is a threat to the earth. Households, industries, insufficient cleanliness, lack of awareness, all are enough to increase pollution in several degrees. With increased consumption of water, it is being equally polluted. Thus many aquatic plants and animals, humans, other land animals are regularly dying after intaking the dirty water.
This is harming our ecosystem. So we must preserve freshwater. It is important and is available in little amount. Clean water can exhaust at any moment. It is our duty even to preserve the rainwater and use it. Every drop of water means life. A correct utility of it is the best way.
So, that was all about writing short essays on Water. In this session above, I have adopted a simplistic approach to writing all these essays for a better understanding of all kinds of students. You can let me know your queries by commenting down below. If you want to read more such lessons on various important topics regarding English composition, keep browsing our website. Thank you.

NEW YORK (AP) — A U.S. government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children.
The report, based on an analysis of previously published research, marks the first time a federal agency has determined — “with moderate confidence” — that there is a link between higher levels of fluoride exposure and lower IQ in kids. While the report was not designed to evaluate the health effects of fluoride in drinking water alone, it is a striking acknowledgment of a potential neurological risk from high levels of fluoride.
Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear , according to the U.S. Centers for Disease Control and Prevention. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.
“I think this (report) is crucial in our understanding” of this risk, said Ashley Malin, a University of Florida researcher who has studied the effect of higher fluoride levels in pregnant women on their children. She called it the most rigorously conducted report of its kind.
The long-awaited report released Wednesday comes from the National Toxicology Program, part of the Department of Health and Human Services. It summarizes a review of studies, conducted in Canada, China, India, Iran, Pakistan, and Mexico, that concludes that drinking water containing more than 1.5 milligrams of fluoride per liter is consistently associated with lower IQs in kids.
The report did not try to quantify exactly how many IQ points might be lost at different levels of fluoride exposure. But some of the studies reviewed in the report suggested IQ was 2 to 5 points lower in children who’d had higher exposures.
Since 2015, federal health officials have recommended a fluoridation level of 0.7 milligrams per liter of water, and for five decades before the recommended upper range was 1.2. The World Health Organization has set a safe limit for fluoride in drinking water of 1.5.
The report said that about 0.6% of the U.S. population — about 1.9 million people — are on water systems with naturally occurring fluoride levels of 1.5 milligrams or higher.
“The findings from this report raise the questions about how these people can be protected and what makes the most sense,” Malin said.
The 324-page report did not reach a conclusion about the risks of lower levels of fluoride, saying more study is needed. It also did not answer what high levels of fluoride might do to adults.
The American Dental Association, which champions water fluoridation, had been critical of earlier versions of the new analysis and Malin’s research. Asked for comment, a spokeswoman late Wednesday afternoon emailed that the organization’s experts were still reviewing the report.
Fluoride is a mineral that exists naturally in water and soil. About 80 years ago, scientists discovered that people whose water supplies naturally had more fluoride also had fewer cavities, triggering a push to get more Americans to use fluoride for better dental health.
In 1945, Grand Rapids, Michigan became the first U.S. city to start adding fluoride to tap water. In 1950, federal officials endorsed water fluoridation to prevent tooth decay, and continued to promote it even after fluoride toothpaste brands hit the market several years later. Though fluoride can come from a number of sources, drinking water is the main source for Americans, researchers say.
Officials lowered their recommendation for drinking water fluoride levels in 2015 to address a tooth condition called fluorosis, that can cause splotches on teeth and was becoming more common in U.S. kids.
Separately, the Environmental Protection Agency has maintained a longstanding requirement that water systems cannot have more than 4 milligrams of fluoride per liter. That standard is designed to prevent skeletal fluorosis, a potentially crippling disorder which causes weaker bones, stiffness and pain.
But more and more studies have increasingly pointed to a different problem, suggesting a link between higher levels of fluoride and brain development. Researchers wondered about the impact on developing fetuses and very young children who might ingest water with baby formula. Studies in animals showed fluoride could impact neurochemistry cell function in brain regions responsible for learning, memory, executive function and behavior.
In 2006, the National Research Council, a private nonprofit organization in Washington, D.C., said limited evidence from China pointed to neurological effects in people exposed to high levels of fluoride. It called for more research into the effect of fluoride on intelligence.
After more research continued to raise questions, the National Toxicology Program in 2016 started working on a review of the available studies that could provide guidance on whether new fluoride-limiting measures were needed.
There were earlier drafts but the final document has repeatedly been held up. At one point, a committee of experts said available research did not support an earlier draft’s conclusions.
“Since fluoride is such an important topic to the public and to public health officials, it was imperative that we made every effort to get the science right,” said Rick Woychik, director of the National Toxicology Program, in a statement.
Malin said it makes sense for pregnant women to lower their fluoride intake, not only from water but also from certain types of tea. It might also make sense to have policy discussions about whether to require fluoride-content on beverage labels, she said.

Re “ Pipe the Great Lakes to California? We Might Have To ,” by Jay Famiglietti (Opinion guest essay, “What to Eat on a Burning Planet” series, Aug. 9):
Professor Famiglietti’s essay about tapping the Great Lakes’ water supply drowns an important call for better national water planning under the specter of water diversion on a massive scale. Here’s why the idea is a nonstarter — and a dangerous distraction.
First, a better governance framework prevents it. The U.S.-Canadian Great Lakes Compact rules out diversion outside the Great Lakes basin with few exceptions.
Second, even if technically possible to move Great Lakes water west, the costs in terms of dollars and energy are unbearable. Hundreds of power plants would be required just to lift water over the Continental Divide and wouldn’t make a dent in the drought.
Third, a combination of engineering and poor governance got us into the Western water crisis, turning California into the nation’s breadbasket at great cost to ecosystems and economies. We can’t just engineer our way out of it.
People and industry will move, as they always have, where the climate is favorable and water and other resources are abundant. This migration is already underway, according to recent San Francisco Fed research and the choice by several high-profile industries to locate in areas of greater resilience.
As a water industry leader, I agree with Dr. Famiglietti on a single point: Smarter national water planning and policy are necessary and urgent, both for regions facing water scarcity and those, like the Great Lakes, coming under increased pressure because of our freshwater abundance. Today. Before it’s too late.
