Thank you. I am going to keep going, if you don't mind, because I still have some time left.
Let's come back to natural resources. I really appreciated what my colleague, Mr. Cullen, was saying earlier about natural resources, and about oil in particular. Clearly, there is research to be done on sustainable development.
Currently, we are being subjected to something else. You are somewhat familiar with the situation. Inevitably, with a change of government, everything that was done before is no good, and everything that is being done now is going to be better. I am sure you are finding this situation every bit as difficult as we are.
However, a lot of proposals have been made for a switch to ethanol. Have you done any studies specifically on ethanol, not just environmentally, but also in terms of sustainable development?
