 I look at how humans affect coastal ecosystems, so if you think about Finding Nemo in that movie where they say all drains lead to the ocean, that really is the case. So when you think about what we're doing on land and how that potentially runs into the ocean, we want to make sure that what we're doing isn't affecting these coastal ecosystems. In estuaries, which is where the freshwater meets the saltwater, is really the last line of defense between what we're doing on land and what's happening in the ocean. I'm looking at a couple different stressors in New Zealand, and the first is nutrient pollution, so how runoff of nitrogen and phosphorus, which are key components in a lot of fertilizers, are impacting these systems, but then nutrient pollution isn't occurring by itself. So there are other things happening simultaneously. So we also have sediment pollution because our land practices are changing, which means that we may be getting more sediment coming from the land or soil. But I think it would be really great to kind of see if there's any what's deemed synergistic impacts or additive effects. So instead of just adding each of these effects as one and saying that this is the overall impact, if we put them together and they're worse than we anticipate, that would be important for planning for the future.
