[color=red][size=10.5pt][b]1.[/b][/size] [/color][size=10.5pt][b][color=red]Ok,another ancient Greek philosophy we need to discuss is Aristotle. Aristotle's ethical theory[/color].[/b][/size] [color=lime][size=10.5pt][b](gist purpose question)[/b][/size][/color] [size=10.5pt]What Arictotle's ethical theory is all about is this: he is trying to show you how to be happy and what true happiness is.[/size] [size=10.5pt][/size]Q ^5wD"mEn&s
[size=10.5pt]Now why is he interests in human happiness? It's not just because it's something that all people want or aim for. It's more than that. But to get there we need to first make a very important distinction. Let me introduce a technical terms. Extrinsic value and intrinsic value.[/size] [size=10.5pt][/size]
Du6x ^~&vp
[size=10.5pt]To understand of Aristotle's interested in happiness, you need to understand this distinction. Some things we aim for and value. Not for themselves but for what they bring about. In addition to themselves. If I value to something as a means to something else, then it has what we will call extrinsic value. Other things we desire and hold to the valuable for themselves belong. If we value to something not as a means to something else but for is only sake , let us say that it has intrinsic value.[/size] [size=10.5pt][/size]Amw
l a-|x Go
[size=10.5pt]Exercise, there may be some people value to exercise by itself but i don not. I value exercise because if I exercise I tend to stay healthier than I would if I didn't So I desire to engage in exercise and [/size][size=10.5pt][b]I [/b][/size][color=red][size=10.5pt][b]2[/b][/size] [size=10.5pt][b]value exercise extrinsically[/b][/size][/color] [size=10.5pt],[/size] [size=10.5pt][font=宋体][color=lime][b]（filled out looks)[/b][/color][/font] [/size][size=10.5pt]not for its own sake but as a mean to something beyond it.it brings me good health.[/size] [size=10.5pt][/size]
MwT nx%D/X#w
N
[size=10.5pt][b]Health[/b][/size] [size=10.5pt],why do I value good health? Well,here it gets a little more complicated for me. um,health is important for me because I can not do other things I want to do. Play music ,teach philosophy if i am ill. So health is important to me ---has value to me as a mean to a productive life. But health is also important to me because i just kind of like to be healthy it feels good. It's pleasant to be healthy unplesant not to be.so to some degree I value [/size] [color=red][size=10.5pt][b]health both for itself and as a means to something else. Productivity, it's got extrinsic and intrinsic value for me. [/b][/size][/color][color=lime][size=10.5pt][b](filled out looks)[/b][/size] [size=10.5pt][/size]p7V!^^7c)o
[/color][size=10.5pt]Then there's some things that are just valued for themselves. I am a musician, not a professional musician i just [/size][color=red][size=10.5pt][b]play a musical instrument for fun. Why do I value playing music?[/b][/size] [size=10.5pt]Well, like most amateur musicians ,[/size] [size=10.5pt][b] I only play because well I just enjoy it, it's something that's an end in itself.[/b][/size][/color] [size=10.5pt][b][color=lime](filled out looks[/color])[/b][/size] [size=10.5pt][/size]

[color=red][size=10.5pt]5[/size] [size=10.5pt]Now something else I value is teaching. Well it brings a modest income but I could make more money if i do other things. I'd do it even they didn't pay me,i just enjoy teaching.[/size]
(M"RBph6B7F't;d ?i2N
[/color][color=lime][size=10.5pt][b](understanding the function of what is said question)[/b][/size][/color] [size=10.5pt]In that sense it's an end to itself. But teaching is not something that is always[/size] [color=red][size=10.5pt][b]intrinsic value for all people[/b][/size] [/color][size=10.5pt][b][color=red](what type of value it has for her?[/color] [color=lime]Filled out looks )[/color][/b][/size] [size=10.5pt][b].[/b][/size] [size=10.5pt]And that 's true generally. Most things that are enjoyed in and of themselves vary from person to person. Some people value teaching intrinsically,but others don't. [/size][size=10.5pt][/size]
}"Vq%K
J
[size=10.5pt]So how does all this relate to human happiness? Well Aristotle's asks: is there something that all human brings value,,,and value only intrinsically for its own sake and only for its own sake? If you could find such a thing that would be the universal final good or truly the ultimate purpose to go for all human brings.Aristotle thought the answer was yes. What is it?happiness,[/size] [color=red][size=10.5pt]3[/size] [size=10.5pt][b]everyone will agree he argues ,that happiness is the ultimate end to be value for itself and only for itself.[/b][/size][/color] [color=lime][size=10.5pt][b](detail question)[/b][/size]
e'z{N+OcnK W
[/color][size=10.5pt]So what others purpose is there in being happy. What does it yield?the attainment of happiness becomes to be highest or ultimate for Aristotle.[/size] [size=10.5pt][/size]S d
Q2V B&z9p ^i*| V
[size=10.5pt]The next questions that Aristotle raise is what is happiness.we all want it ,we all desire it.we all seek it.it's the goal we have in life.but what is it?how do we find it?here he notes with some frustration,people disagree.[/size] [size=10.5pt][/size]
v$Bf;ri4hi
[size=10.5pt]But he does give us a couple of criteria or features, to keep in mind as we look for the true human happiness is. True human happiness should be as he puts it complete .complete in that it's all we require.well true human happiness if you had that,what else you need?nothing.[/size] [size=10.5pt][/size]
Ui0B0t4X R1F:L
[size=10.5pt]and second ture happiness is something should be something that i can obtain on my own.i should not have to rely on others people for it.many people value fame,and seek fame ,fame for them becomes the goal[/size] [color=red][size=10.5pt][b].[/b][/size] [size=10.5pt][b]4[/b][/size] [/color][size=10.5pt][b][color=red]but accourding to arictotle this won't work either. Because fame depends altogether too much on other people.i can not get it on my own[/color][color=lime],（detail question)[/color][/b][/size] [size=10.5pt]without help from other people.[/size] [size=10.5pt][/size]6x8?tT ^ge(u.Up
[size=10.5pt]in the end ,Arictotle said that the true happiness is the exercise of reason. A life of intellectual contemplation,..of thinking . So let's see how he comes to that?[/size] [size=10.5pt][/size]

[size=10.5pt][size=10.5pt]Listen to part of a lecture in an astronomy class. You will not need to remember the numbers the professor mentions.[/size] [size=10.5pt][/size]:` SP.zrhOQ

[size=10.5pt]Ok let's get going. Today I am going to talk about how the asteroid belt was discovered. And ...I am going to star from some numbers on the board. Here they are; we will start with zero, then 3,,,6,,12,,uh,tell me what I am doing.[/size] [size=10.5pt][/size]
DB{iW} hwJ
[size=10.5pt]Multiplying by two?[/size] [size=10.5pt][/size]? Ub s4L"F
[size=10.5pt]Right I am doubling the numbers ,so 2 times 12 is 24, and the next one I am going to write after 24 would be 48, 48,then next 96,we will stop here for now. Now I will write another row of numbers under that. Tell me what I am doing.[/size] [size=10.5pt][/size]
+Gv-NH P
E
[size=10.5pt]4,7 10 how am I geting the second row? Adding 4 to the numbers in the first row. I am adding 4 to each number in the first row to give you a secend row. [/size][size=10.5pt][/size]_/n M-V cRO'{a
[size=10.5pt]So the last two will be 52, and 100. And now tell me what I am doing?[/size] [size=10.5pt][/size]'I$t;p n(\;E
[size=10.5pt]Putting in a decimal?[/size] [size=10.5pt][/size]:tVd(T7LP a8@
[size=10.5pt]I divided all those numbers by ten by putting in a decimal point.[/size] [size=10.5pt][/size]
tr:vS _
[size=10.5pt]Now I am going to write the names of the plates under the numbers. Mercury Venus Earth Mars[/size] [size=10.5pt][/size]1I Et |

[size=10.5pt]So what did the numbers mean? Do you remenber from the reading?[/size] [size=10.5pt][/size]
f t s(M1VL f;L
Z
[size=10.5pt]Is it the distance of the planet from the sun?[/size] [size=10.5pt][/size]
D9Nu u'Wm
[size=10.5pt]Right in astronomical units. Not perfect but tantalizingly close. The value for mars is off by six or seven percent so it's,,,but it's within 10 percent of the average distance to mars from the sun. But I can not have to skip te one after mars for now. Then jupiter's right there at 5 point something and then saturn is about 10 astronomical units from the sun. [/size][size=10.5pt]Well this pattern is known as bode's low.[/size] [size=10.5pt][/size])k`| }:T
[color=red][size=10.5pt]4[/size] [size=10.5pt]Um it isn's a scientific law, not in the sense of predicting gravitation mathematically or something.(understanding the function of waht is said replay)[/size][/color] #G,{\+u[ eKt
[color=red][size=10.5pt]1[/size] [size=10.5pt]But it's attemping a pattern in the spacing in the planets. (detail question)[/size][/color] [size=10.5pt]And it was noticed by bode hundrends of years ago. [/size][color=red][size=10.5pt]6[/size] [/color][size=10.5pt][color=red]Well you can imagine that there was some interest in why the 2point8 spot in the pattern was skipped. [/color]And um,,,but there's saything obvious there in the early telescopes. [/size][size=10.5pt]Then what happend the late 1700s? They discovery of...[/size] [size=10.5pt][/size]
a/[ ?t'^3W-k
[size=10.5pt]Another planet?[/size] [size=10.5pt][/size]

[size=10.5pt]The next planet out , uranus, after saturn.[/size] [size=10.5pt][/size])r,cY?'w:H
[size=10.5pt]And look[color=red][/color][/size][color=red][b][size=10.5pt]5[/size] [/b][/color][size=10.5pt][color=red][b],uranus face in the next spot in the pattern prety nicely[/b][/color].[/size] [size=10.5pt] Um not perfectly but close.[/size] [size=10.5pt][/size] Wn2~ sG
[color=red][size=10.5pt]6[/size] [/color][size=10.5pt][color=red]And so then people get realy excited about the validity of this and finding the missing object[/color]
6SDvtic^ `W9t
[size=10.5pt][color=red][b](making inferences question)[/b][/color][/size] [size=10.5pt]between mars and jupiter[/size] [size=10.5pt][b].[color=red]5 [/color][/b][/size][color=red][size=10.5pt]And telescopes ,remenber , were getting better. (detail question)So people went to work on finding objects would be at that missing distance of the sun.and then in 1801,the object ceres was discovered.[/size][/color] [size=10.5pt][/size]
R)O(KKZL,@ C
[size=10.5pt]And ceres was not in a right place. The missing spot. But it was way to faint to be a planet. It looks like a litter star. Um and because of it star like appearance, um it was called an asteriod.[/size] [size=10.5pt][/size]q @p u;v bI
[size=10.5pt]Ok? Aster is greek for star as in astronomy. And so ceres was the first and is the largest of what became many objects discovered at that the same distance. Now just one thing but all the objects found at that distance form the asteroid belt[/size] [color=red][size=10.5pt][b].2[/b][/size] [size=10.5pt]So the asteroid belt is the most famous success of this bode's law. That's how the asteroid belt was discovered.(gist purpose question) [/size][size=10.5pt][/size][/color]7c(ZV] Ia

[size=10.5pt]Hi everyone. Good to see you all today. Actually I expected the population to be a lot lower today. It typically runs between 50 and 60 percent on the day the research paper is due. Um, I was hoping to have your exams back today but the situation was that I went away for the weekend and I was supposed to get in yesterday at five,[/size] [size=10.5pt][b][color=red]2and I expected to fully complete all the exams by midnight or so, which is the time that I usually go to bed,but my flight was delayed, and I ended up not getting in until one o'clock in the morning. Any way I will do my best to have them finished by the next time we meet.(understanding the function of waht is said replay question)[/color][/b][/size] [size=10.5pt][/size]Q

[size=10.5pt]Ok, and the last class we start talking about useful of plant fibers. In particular,we talk about cotton fibers, which we say were very useful not only in the textile industry but also in the chemical industry, and in the production of many products, such as plastics, paper, explosives and so on. [/size][size=10.5pt][b][color=red]1Today we continue talking about the useful fibers and we'll begin with a fiber that's commonly known as "manila hemp" (gist content questions)[/color][/b][/size] [size=10.5pt][/size]
\0o {"yA9R8b0?
[size=10.5pt]Now,for some strange reason many people believe that manila hemp is a hemp plant.[/size] [size=10.5pt][b][color=red]3But manila hemp is not really hemp. It's actually a member of a banana family.[/color] [/b][/size][size=10.5pt]It even bears a little banana shaped fruits. [/size][size=10.5pt][b][color=red]3The manila part of the name makes sense because manila hemp is produce chiefly in the Philippine islands. Of course the capital city of the Philippines is manila(making inferences questions).[/color][/b][/size] [size=10.5pt][/size]!k e ss5Z H+~
[size=10.5pt]Now as fibers go, manila fibers are very long. They can easily be several feet in length and they're also very strong very flexible. They have one more characteristics that's very important. And that is that they are exceptionally resistant to salt water. And this combination of characteristics --long, strong, flexible, resistant to salt water makes manila hemp a great material for ropes, especially for ropes that are gonna be used on ocean-going ships. In fact, by the 1490's even though the steal cables were available, most ships in united states navy were not moored with steel cables, they were moored with manila hemp ropes.[/size] [size=10.5pt][/size]? F? X,z&l%^G
[size=10.5pt]Now why was that? [/size][size=10.5pt][b][color=red]5Well the main reason was that the steel cables ships degree were very very quickly contact with salt water.(detail questions)[/color] [/b][/size][size=10.5pt]If you've ever been to can francisco[/size] [size=10.5pt][b],[color=red]4 you know that the golden gate bridge is red. And it's red because of the zinc paint that goes on those stainless steel cables[/color]. [/b][/size][size=10.5pt]That , if they start at one end of the bridge and they work to the other end, by the time they finish, it's already time to go back start painting the beginning of the bridge again. [/size][size=10.5pt][b][color=red]Because the bridge was built with steel cables, and the steel cables cannot take the salt air unless they're treated repeatedly with a zinc-based paint.[/color][/b][/size] [size=10.5pt][/size]
'SXQRBm1v
[size=10.5pt]On the other hand, plant products like malina hemp, you can drag through the ocean for weeks on end. If you want to tie your anchor to it and drop it right into the ocean, that's no problem. [/size][size=10.5pt][b][color=red]Because plant fibers can stand up one month even years. And right contact with salt water.(understaning organization questions)[/color] [/b][/size][size=10.5pt]Ok so how do you take plant fibers that individually you could break with your hands and turn them into a rope that' s strong enough to moor a ship weighs thousands of tons? What you do is you extract these long fibers from the manila hemp plant, and then you [/size][size=10.5pt][b][color=red]6take several of these fibers the new group that into a bundle[/color][/b][/size] [size=10.5pt],because by grouping the fibers you greatly increase their breaking strength--that bundle of fiber is much stronger than any of the individual fibers that compose it. And then you [/size][size=10.5pt][b][color=red]take that bundle of fibers and you twist it a little bit(detail questions)[/color][/b][/size] [size=10.5pt], because by twisting it you increase its breaking strength even more, and you take the several of the little bundles and you group and twist them in a bigger bundles, which you then group and twist into even bigger bundles, and so on, until eventually, you end up with a very very strong rope.[/size] [size=10.5pt][/size]2t.Cy6L9Rd;ZJ!G0QZf n n

[size=10.5pt]Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a great ocean of anguish, reaching to the very verge of despair. [/size] [size=10.5pt][/size])NPm6XpsC8C)P J
[size=10.5pt][/size]"Q oX-P yg%jKu
[size=10.5pt]I have sought love, first, because it brings ecstasy - ecstasy so great that I would often have sacrificed all the rest of life for a few hours of this joy. I have sought it, next, because it relieves loneliness--that terrible loneliness in which one shivering consciousness looks over the rim of the world into the cold unfathomable lifeless abyss. I have sought it finally, because in the union of love I have seen, in a mystic miniature, the prefiguring vision of the heaven that saints and poets have imagined. This is what I sought, and though it might seem too good for human life, this is what--at last--I have found. [/size] [size=10.5pt][/size]

[size=10.5pt][/size] P k+Z@ }Do
[size=10.5pt]With equal passion I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. And I have tried to apprehend the Pythagorean power by which number holds sway above the flux. A little of this, but not much, I have achieved. [/size] [size=10.5pt][/size];E$X!j z4{

[size=10.5pt]Love and knowledge, so far as they were possible, led upward toward the heavens. But always pity brought me back to earth. Echoes of cries of pain reverberate in my heart. Children in famine, victims tortured by oppressors, helpless old people a burden to their sons, and the whole world of loneliness, poverty, and pain make a mockery of what human life should be. I long to alleviate this evil, but I cannot, and I too suffer. [/size] [size=10.5pt][/size]

[size=10.5pt]Sometimes I have thought it would be an excellent rule to live each day as if we should die tomorrow. Such an attitude would emphasize sharply the values of life. We should live each day with a gentleness, a vigor, and a keenness of appreciation which are often lost when time stretches before us in the constant panorama of more days and months and years to come. There are those, of course, who would adopt the Epicurean motto of "Eat, drink, and be merry," but most people would be chastened by the certainty of impending death.[/size] [size=10.5pt][/size]
x[S6I [8\
[size=10.5pt][font=宋体] In stories the doomed hero is usually saved at the last minute by some stroke of fortune, but almost always his sense of values is changed. he becomes more appreciative of the meaning of life and its permanent spiritual values. It hasoften been noted that those who live, or have lived, in the shadow of death bring a mellow sweetness to everything they do.[/font] [/size][size=10.5pt][/size]
$l[k |6i7d*k R
[size=10.5pt][font=宋体] Most of us, however, take life for granted. We know that one day we must die, but usually we picture that day as far in the future. When we are in buoyant health, death is all but unimaginable. We seldom think of it. The days stretch out in an endless vista. So we go about our petty tasks, hardly aware of our listless attitude toward life.[/font] [/size][size=10.5pt][/size]
z)` @7l-S NW!ca
[size=10.5pt][font=宋体] The same lethargy, I am afraid, characterizes the use of all our faculties and senses. Only the deaf appreciate hearing, only the blind realize the manifold blessings that lie in sight. Particularly does this observation apply to those who have lost sight and hearing in adult life. But those who have never suffered impairment of sight or hearing seldom make the fullest use of these blessed faculties. Their eyes and ears take in all sights and sounds hazily, without concentration and with little appreciation. It is the same old story of not being grateful for what we have until we lose it, of not being conscious of health until we are ill.[/font] [/size][size=10.5pt][/size]
%_gd0o7l0d
[size=10.5pt][font=宋体] I have often thought it would be a blessing if each human being were stricken blind and deaf for a few days at some time during his early adult life. Darkness would make him more appreciative of sight; silence would tech him the joys of sound.[/font] [/size][size=10.5pt][/size]? u~Wx
[size=10.5pt][font=宋体] Now and them I have tested my seeing friends to discover what they see. Recently I was visited by a very good friends who had just returned from a long walk in the woods, and I asked her what she had observed…"Nothing in particular, "she replied. I might have been incredulous had I not been accustomed to such reposes, for long ago I became convinced that the seeing see little.[/font] [/size][size=10.5pt][/size]4^jF!y z8[s\:k
[size=10.5pt][font=宋体] How was it possible, I asked myself, to walk for an hour through the woods and see nothing worthy of note? I who cannot see find hundreds of things to interest me through mere touch. I feel the delicate symmetry of a leaf. I pass my hands lovingly about the smooth skin of a silver birch, or the rough, shaggy bark of a pine. In the spring I touch the branches of trees hopefully in search of a bud the first sign of awakening Nature after her winter's sleep. I feel the delightful, velvety texture of a flower, and discover its remarkable convolutions; and something of the miracle of Nature is revealed to me. Occasionally, if I am very fortunate, I place my hand gently on a small tree and feel the happy quiver of a bird in full song. I am delighted to have the cool waters of a brook rush thought my open finger. To me a lush carpet of pine needles or spongy grass is more welcome than the most luxurious Persian rug. To me the page ant of seasons is a thrilling and unending drama, the action of which streams through my finger tips.[/font] [/size][size=10.5pt][/size]
7W+I ?!a0~!yB
[size=10.5pt][font=宋体] At times my heart cries out with longing to see all these things. If I can get so much pleasure from mere touch, how much more beauty must be revealed by sight. Yet, those who have eyes apparently see little. the panorama of color and action which fills the world is taken for granted. It is human, perhaps, to appreciate little that which we have and to long for that which we have not, but it is a great pity that in the world of light the gift of sight is used only as a mere conveniences rather than as a means of adding fullness to life.[/font] [/size][size=10.5pt][/size]#S/Ri,q m[)m!n.x:F/O
[size=10.5pt][font=宋体] If I were the president of a university I should establish a compulsory course in "How to Use Your Eyes". The professor would try to show his pupils how they could add joy to their lives by really seeing what passes unnoticed before them. He would try to awake their dormant and sluggish faculties.[/font] [/size][size=10.5pt][/size]p+Rd*D}TY
[size=10.5pt][font=宋体] Perhaps I can best illustrate by imagining what I should most like to see if I were given the use of my eyes, say, for just three days. And while I am imagining, suppose you, too, set your mind to work on the problem of how you would use your own eyes if you had only three more days to see. If with the on-coming darkness of the third night you knew that the sun would never rise for you again, how would you spend those three precious intervening days? What would you most want to let your gaze rest upon?[/font] [/size][size=10.5pt][/size]
N IQJzx1G7f
[size=10.5pt][font=宋体] I, naturally, should want most to see the things which have become dear to me through my years of darkness. You, too, would want to let your eyes rest on the things that have become dear to you so that you could take the memory of them with you into the night that loomed before you.[/font] [/size][size=10.5pt][/size]6R

[size=10.5pt]Listen to part of a talk in an environment science class.[/size][size=10.5pt][/size]4m

[size=10.5pt]So I want to discuss a few other terms here. Actually, some um, some ideas about how we manage our resources.[color=red][b] Let't talk about what that, what that's means. [/b][/color]If we take a resource like water,well,maybe we should get a litter bit more specific back up from the more general case- and talk about underground water in particular.[/size][size=10.5pt][/size]

[size=10.5pt]So hydrogeologists have tried to figure out -how much water can you take out from underground sources? This has been an important question. Let me ask you guys; how much water based on what you know so far, could you take out of say, an aquifer...under the city, uh,,as much as would get re-charge?[/size][size=10.5pt][/size]h eVU(z:k.E/x(c
[size=10.5pt]Ok,so we wouldnt take any more than naturally comes into it. The implication is that, well if you only take as much out as comes in, you're not gonna deplete the amount of water that's stored in there,right?[/size][size=10.5pt][/size]

[size=10.5pt][color=red][b]Wrong,but that's principle. That is the idearbehind how we manage our water resource supplies. It's called safe yield. Basically what does this methods says is that you can pump as much water out the system as the normally re-charge.[/b][/color] As naturally follow back in. So this principle of safe yield is basic on balancing what we take out with what get re-charge. But what is does worth is knows how much water naturally come out the system. In a natural system, a certain amount of the recharge comes in and a certain amount of water naturally flows out through springs streams and lakes. And over the long term the amount that's stored in the aquifer doesn't really change much. It's balanced .. Now humans come in ...and start taking water out of the system. How have we changed the equation?[/size][size=10.5pt][/size]

[size=10.5pt]It's not balanced anymore?[/size][size=10.5pt][/size] K!k.~3V mG'^5u
[size=10.5pt]Right, we take water out but water also naturally flows out. And the recharge rate doesn't change so the result is we have reduced the amount of water that happens, that can affect surface water. How? Well, in underground systems there are natural discharge points--places where the water flows out of the underground systems, out to lakes and streams. [color=red][b]Well, a drop in the water level can mean those discharge points will eventually dry up. That means water's not getting to lakes and streams that depend on it[/b][/color]. So we have ended up reducing th surface water supply, too.[/size][size=10.5pt][/size]?!^I vv Al
[size=10.5pt]You know ,in the state of Arizona we're managing some major water supplies with this principled safe yield, under a method that will eventually dry up the natural discharge points of those aquifer systems. Now why is this an issue?well, aren't some of you going to want to live in this state for a while? Want your kids to grow up here, and your kids' kids?you might be concerned with ,,,does general definition of sustainable is will there be enough to meet the needs of the present without compromising the ability of the future to have the availability...to have the same resources?[/size][size=10.5pt][/size]Z~ U {4iT&d8GQD
[size=10.5pt]Now i hope you see that these two ideas are incompatible sustainability and safe yield. Because what sustainability means is that it's sustainable for all systems dependent on the water for the people that use it and for uh, for supplying water to the dependent lakes and streams. [color=red][b]So I am gonna repeat this so if we're using a safe yield method,if we are only balancing what we take out with what gets recharged but don;t forget waters also flowing tour naturally then the amount stored underground is gonna gradually get reduced and that's gonna lead to another problem. [/b][/color]These discharge points where the water flows out to the lakes and streams they are gonna dry up. Ok/[/size][size=10.5pt][/size]
