Keep Our Water Clean: Clean Water Act The Clean Water Act has made advances to our society that have helped our environment to flourish with life. The objective of the Act when it was enacted in 1972 was to restore and maintain the chemical‚ physical‚ and biological integrity of the Nation’s water. This objective was accompanied by other statutory goals to eliminate the discharge of pollutants into waters used by boats by 1985 and to attain waters deemed "fishable or swimmable" by 1983. So far

In Rudyard Kipling’s fiction story‚ "Rikki-tikki-tavi"‚ the theme of survival is demonstrated through Rikki’s actions during his many conflicts within the story. For example‚ Nag and Nagaina discuss that they should kill the family to raise their young Cobras‚safely(28)‚Rikki-Tikki kills Nag in the bathroom to protect his family(29)‚ Rikki-Tikki kills Nagaina to save Teddy (33). Rudyard first introduces the idea survival in the scene where Nag and Nagaina discuss that they should kill the family

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water?

The importance of nature in our lives In old days we lived very closely with nature in one form or another. This was necessary‚ as we did not live in the sophisticated way we do at the moment‚ but by listening and feeling our connection with nature. By no longer doing so we have mislaid a lot of the ancient knowledge that we once had at our fingertips It was possible in the recent past to stand and look up at the skies‚ and see where the stars were and the story that they had to tell us!

Water has importance inside cells and externally. This may be because it has interesting chemical and physical properties; it can be found naturally in all three of its states. However its molecules are bonded together by hydrogen bonds‚ this raises its melting and boiling points‚ i.e. its boiling point would be -120¢ªC rather than 100¢ªC. Also because it contains slightly negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. <br> <br>Water has been called
