water= H2O

Water is in 3 states: Liquid, solid, Vapor

71% of the earths surface

When born we are made up of 75% of water

We need water to survive.

      Water is one of the biggest resources we need to survive. We can only live 8-14 days without water. It depends on the individual and how you use the water that is in your body. Urine, tears,.. etc. Water makes up the majority of a human body,(55-75%) and the majority of the earth (71%). So since water is every where how come some people still struggle to get the water they need to survive. People all over the world still can’t get clean water and have to walk miles to even get water for there families.

   How else do we use water other then to survive?

   We use water everyday in the U.S. We take showers, we swim, we water our lawns, but how much of this water is being used to help and clean us and how much is being waisted and is being used to excessive amounts. For example when people brush their teeth and leave the water running the amount of water that goes down the sink before you rinse off your tooth brush is being waisted and going down your drain for no reason. According to Suite101.com they state that a single person uses 1,189 gallons of water a day. But how much of that actually went to good use? IF you had a leaky faucet at home and it only dripped 5 times a minute it would waste 7,200 drips a day which equals 1 liter in a day, 173 gallons per year, which is the equivalent to  3 baths in a year. But lets say you had a faucet that leaked 60 times a minute you would waist 86,400 drips a day, 5 gallons a day, and 2,082 gallons a year. This is like waisting 41 baths a year! This is according to the USGS website.

How much of our earths water is suitable for mankind?

Our earth is made up of  71% of water and 97% of this water is salt water. 2% of the usable water is in Ice caps. Leaving only less then 1% of this water as fresh usable water. Good thing that’s alot of water! or is it?  A lot of people in this world and especially in the U.S. we take water for granite. But what if it runs out? Will we melt the Ice caps. Find a way to get the salt out of the water.
