If I may, I will answer in English.
In the two areas you mentioned—natural resources and energy, and the environment—vis-à-vis also commercialization, there are a number of issues and challenges in Canada that need to be addressed and that can make significant progress through research in the next five to ten years.
Water is one area. Water is very important to us environmentally, the water and energy nexus. For instance, in Alberta with the oil sands, technology has improved significantly in the last 15 to 20 years such that, at the current cost of a barrel of oil, it is profitable to upgrade the tar sands. But there are challenges. There are technology challenges, and there are environmental challenges. So it really spans both areas, energy and the environment.
The consumption of water in the process used to upgrade oil sands is not sustainable. We're using far too much water, so we need to develop some new technology that either reduces the consumption of water or a totally different technology that doesn't use water at all. A lot of important research needs to be done in that area, and from an environmental perspective, the byproducts in the upgrading of oil are mountains of solids, sulphur-containing solids and others, that are damaging to the environment. That issue has to be addressed. So that's just one.That's the water issue, and as well, there is the oil sands issue.
There are areas in Canada that, for the future, could yield new benefit. One is research in the Arctic, the north, both from an environmental point of view and from an energy perspective. That too is important. There is sensor technology for environmental applications, not only discovery of new places to farm—more advanced GPS technology—or security-based work to protect our environment, but other applications as well.
