Our planet earth has always had the same amount of water. The water we use today was also there for the dinosaurs to drink. And through the water cycle, water can be found everywhere. It is always moving and changing states as a liquid, solid or gas.
Water can be found in streams, rivers and lakes. It’s in the air and underground. It is the glaciers, rain and snow. And it’s in our food, plants and bodies.
Earth, also known as the blue planet, has a lot of water – about 71 per cent of our planet is covered in water. But how much of it is drinkable fresh water? First look at the oceans – that’s a lot of water. In fact 97 per cent of all water is salt water – water we can’t drink without desalinating or removing the salt. That leaves three per cent remaining as fresh water. About two per cent of all fresh water on our planet can be found underground as groundwater. Water is always travelling, even if it has to take the slow route, underground through rocks and dirt.
Locally Waterloo Region is part of the Grand River watershed managed by the Grand River Conservation Authority. But what is a watershed? Is it a shed made out of water? Nope. A watershed is an area of land that drains into the same body of water. Think of it like a tree branch. In Waterloo Region groundwater seeps into small waterways such as Schneider’s Creek, Laurel Creek and Mill Creek that drain into the larger Grand River. The Grand River and many other watersheds drain into Lake Erie and eventually into the Atlantic Ocean.
Have you ever watched the National Film Board movie “Paddle to the Sea”? The movie reminds me of a watershed. It is about a child who carves out a man in a canoe and sets it on a frozen stream waiting for the spring thaw. The movie follows the canoe as it travels from the stream to larger waterways and finally to the ocean.
The water cycle and the fact we all live in a watershed are reminders we all share the same water and we all live downstream from someone else. And why we all have a role to play when it comes to protecting water.
What do you think are the biggest issues for water? What steps should our community take to protect water? Do you have tips to share that can help others be water protectors?
