How can we protect our water?
In Science we ask questions to help us figure out what the problem is.
In the Minds On section, you considered the ways living things use and depend on water.
Water is important in people’s lives! We need it to drink, wash, cook, and grow food. We need not just any kind of water. We need fresh, clean water.
Seawater is salty, so we cannot drink it or grow plants with it.
What we need is freshwater! Freshwater is found in lakes, rivers, streams, or underground. Freshwater is the water people can drink and use every day.
Since freshwater is only 3% of the water in the world, it’s important to protect it.
How can we protect water?
One way we can protect water is with activism! Activism is when people work to make change. Activists are people and organizations that are working to make important changes.
In this learning activity, we will learn about young activists that are working to understand more about water and protect water in their community and beyond.
Ontario connection
This learning activity highlights people, places, or innovations that relate directly to the province of Ontario. Enjoy the exploration!
Sometimes water can come from smaller lakes, rivers, underground wells, or ponds. In Ontario, many people get their drinking water from the Great Lakes, the largest source of fresh water in the world.
Time to learn! We can learn things from different places and people.
Tyler and Alex Mifflin are also known as the Water Brothers. They travel the world to learn about the problems that people are facing with water.
The brothers have created a TV show known as the Water Brothers. In their TV show, they share their experiences and conversations with local people and experts.
They explore the ways that water connects people. Their TV show also helps the brothers share their learning with Canadians. The Water Brothers can help Canadians understand the problems and the actions we need to take to protect water.
The following clip is an example of how the Water Brothers are working to help others learn about the water challenges that people experience.
In the clip, the Water Brothers visit the Athabasca glacier in Alberta. The water from this glacier spreads across Canada. Climate change is causing the glacier to melt a lot faster than it normally would.
As you explore, consider the following questions:
- What are the Water Brothers trying to do?
- What are they doing to achieve it?

Autumn is Anishinaabe and comes from Wikwemikong First Nation on Manitoulin Island. Manitoulin Island is the largest island on fresh water in the world.

Many Indigenous communities have teachings about the important relationship between women and water. Some Nations, like Autumn’s, believe that women have a responsibility to protect water. It is important that water is cared for by people so we have clean water in the future.
Autumn was part of a ceremony in a village that did not have access to clean water. She learned about how important clean water is.
As Autumn learned more, she decided to share her experiences with people around the world. For example, in 2016, she met Canadian Prime Minister Justin Trudeau. In 2019, she spoke to hundreds of international guests at the United Nations.
Autumn takes every opportunity to be a water activist to keep water protected for the future. In the following video, Autumn is at a water summit in Ottawa, Ontario.
