McCauley: “It is that transition from harvest to habitat degradation that has us so concerned. We think this is a really transitional event in ocean wildlife health. When we talk about degrading health in the oceans, it’s usually about harvest. But we ran this environmental history of what we’ve done to wildlife on land, in parallel to this review of what we are doing to wildlife in the oceans. On land what we did was we started first by simply hunting wildlife. And then we switched over to wanting the same resources and wanting the same space that these wildlife were using. This transition was most pronounced during the Industrial Revolution, when our cities were growing and we needed resources for everything that was coming out the other end of these fabrication lines. When we look at how extinction of terrestrial wildlife changes over time, you see a pretty distinct signature that things pick up right there, when we switched over to damaging wildlife habitat. It just makes intuitive sense – if you hunt individuals intensely that’s going to have negative impacts, but if you go through and actually ravage the homes of these animals, it’s going to be a lot harder to recover and the impacts are going to be more profound.
