I'll take a stab at that, and I'll ask Pierre if he has anything to add from a research scientist's perspective.
I'll just come back to a point that I made a moment ago: when we think about some of the trends around climate change and the warming of the ocean and the changes in the ocean, we're really thinking of longer time frames.
When we're right up against a change, it's difficult to adapt. The longer we have and the earlier we start, the easier it is for us to detect changes over time. We rely on our monitoring programs to do that. I spoke to the monitoring that we're doing on all three oceans on ocean acidification, which comes to your point.
It's not to suggest that that change and the absence of copepods in this example will happen tomorrow, next year, or even in five years. That was an example that was meant to directly link the challenge with ocean acidification to something that's very tangible: a food source for a very important species for western Canada.
