  • Everything we do involves water. To produce the food, to grow the crops, to raise the cattle

  • that are the basis of our food production, we need water. All our industrial processes

  • require water - whether it’s mineral extraction, whether it's generation of energy, or manufacturing

  • of goods, it all requires water. In addition water is the basis of the life support system

  • of our Earth.

  • Although we are known as a water planet, a very minor part of that water is actually

  • available for humans to live on. We need to ensure that we have a safe and reliable supply

  • for humans.

  • Why do we have to care, as Canadians, about water? We have the Great Lakes basin, which

  • is home to one of the largest freshwater resources in the world, and yet a very minor part of

  • that is actually being recycled. So basically, as we draw water from that, it’s like having

  • money in the bank. We are taking the money out, and were not putting it back. And

  • so we need to focus on protecting that water stock, as well as focusing on what we are

  • doing as we transform that water coming in and leaving.

  • Water has no boundaries. It can go from the terrestrial to the aquatic system. It goes

  • downstream across different jurisdictions. So we have water that the United States, for

  • example, depends on a great deal. In fact some of the work that I have done has shown

  • that many of the Americans are looking to the water supplies of Canada that might sustain

  • them into the future. Water is an international issue, not just a local one.

  • In many areas of the world, development is limited by the availability of clean water.

  • If we can increase the availability of clean water, we automatically will generate

  • economic prosperityso there is a direct link between water availability and prosperity.

  • Green technologies often are essentially mimicking what nature is already doing. So by better

  • understanding at a fundamental level how a natural process works actually can lead to

  • the development of new green technologies. The research we are doing is essential to

  • provide the knowledge base and the facts that are necessary to inform public debate about

  • water issues and also the knowledge is needed to develop sound policies in terms of water.

  • Where we are taking this, is starting to work very closely with policy makers. So we are

  • taking the science that we're learning from the lab and the field, and being able to come

  • up with tools that governments can then use to protect those water resources on the landscape.

  • Innovation in water directly implies innovation in the economy. It creates jobs, it leads

  • to economic prosperity, and it also increases our well-being as humans. It’s an important

  • part of our lives.
