Generally, we don't have all the science we need. That's why we advocate for the precautionary approach and also a commitment to adaptive management and learning around the issues that we are either concerned about or that conservation measures are being applied to. There hasn't been an ability to invest in the kinds of science we need, and we're seeing changes faster than we anticipated. Therefore, new kinds of science are required. For some of it, many years are needed to get relevant trend data.
