Today, during question period, the issue of the ozone layer was raised. We know that in the far north, they use mostly diesel fuel. With development, that use will increase even more. You referred to alternatives, to wind energy in particular. The fact remains that the use of diesel will increase as well as the risk of pollution and problems related to the ozone layer. A thinner ozone layer means that workers may suffer the consequences, such as skin cancer among others. That means that there will be social costs and health costs involved. We are talking about workers who are going to have to agree to work under such conditions.
Given this new problem, are you doing research and development to position yourselves and find solutions? What is the situation currently?
