Water is an invaluable resource; we absolutely cannot live without it. Did you know that you can survive about a month without food, but only 5 to 7 days without water? That is because about 60 percent of the human body is made up of water: the brain is composed of 70 percent water; blood is 82 percent water; and the lungs are nearly 90 percent water! In order to stay healthy, human beings should drink about 8 cups of water per day.
Well, we already know that our bodies use a lot of water, but have you ever stopped to think about all of the different ways you use water in your life every day? We use water all of the time in our homes, at school, and even while we play. In fact, the average single-family home uses 262 L of water each day. Why do we use so much? Toilets use the most water, while washing machines and showers contribute significantly.
Where does all of this water come from? How does it make its way into our homes? Is it always safe? How can we practice Conservation so that we are not wasting water? In exploring this section you will find answers to all of these questions, and many more.
Water Around the World
- Did you know that around 70-75% of the earth is covered in water?
- In Canada, there is more water underground than on the surface. In fact, around the globe much more fresh water is stored under the ground in aquifers than on the earth's surface. Glaciers store about 75% of the entire world's freshwater.
- With approximately 8% of its territory covered by lakes, Canada has more lakes than any other country in the world.
- About 2 million tons of waste is dumped every day into rivers, lakes and streams. One liter of wastewater pollutes about 8L of freshwater; and one drop of oil can render up to 25 L of water unfit for drinking.
- Even though water covers nearly 3/4 of the earth's surface, most of the world's people must walk at least 3 hours to fetch water. There are over 1-Billion people in the world that lack access to safe drinking water, 2.4-billion that lack access to adequate systems for sanitizing the water.
- The overall amount of water on our planet has remained the same for two billion years.
