To protect the orcas in Puget Sound, we would need to increase the number of salmon and reduce the level of toxins they carry. And reduce the level of sea noise from boats.

Over time, the more humans we make, the less room there will be for other species to survive on Earth. I imagine Norma Sanchez's great grandchild asking per parents, "Why did you have me, knowing what disasters were likely to be waiting for me before I got to be 40?"
