I think any industrial activity has some impact. I'll talk in very general terms. Air emissions have an impact on the environment. It's one that the industry is addressing quite well, and in fact, emissions are decreasing overall, especially in our coastal environments, due to international and North American regulations. So that's a positive story.
Recently we're hearing more about acoustic disturbance. That is the impact on marine mammals of underwater noise that vessels produce. Certainly it's a very prominent issue in western Canada at the moment and one that government and industry and a lot of conservation organizations are putting a lot of effort into to try to find solutions. The Port of Prince Rupert and the Port of Vancouver are both leading significant environmental programs to support understanding the issue better, doing the research, and then helping to find ways to mitigate underwater noise. That's probably the largest at the moment.
Noise and light have some impact, especially in the kinds of markets that we serve in your constituency, shipping agrifood. Sometimes vessels need to anchor, and they anchor occasionally in the vicinity of communities. That's one we're very aware of. We're working closely with Transport Canada, indigenous and coastal communities to try to reduce that impact.
