A hallmark of the Endangered Species Act is the requirement that decisions be made solely on the basis of scientific data. Congress is supposed to rely on that data.
This act was brought to bear in 1973 under a Republican President with a very important mission: to protect species at risk of extinction and to promote the conservation of ecosystems and habitats necessary for the survival of those species.
For a species to be considered recovered, science must show that it has returned to suitable habitats with durable populations that can persist safely and endurably into the foreseeable future. That is the law. Today, wolves have returned to only 10 percent of their historic range and do not meet the Endangered Species Act requirements for delisting. That is the law.
Gray wolves once numbered in the millions across North America, from forests and plains to deserts and mountains. But wolves, with insatiable, rapacious cruelty, were hunted, trapped, and poisoned--and other actions to kill and eradicate them--to near extinction by the mid-20th century in all of the lower 48 States.
There is this growing sympathy and empathy in the American public for a species that has endured such cruelty and ruthlessness at human hands over the centuries--a species that is the forbear of the dogs we love and cherish in our lives.
As apex predators, gray wolves, we now know, play a vital role in keeping the entire natural ecosystem in America healthy. When wolves were brought back to places like Yellowstone National Park, it transformed the park. More birds, beavers, and fish returned.
Research from Wisconsin, my colleague's home State, reveals the overwhelming net benefits of healthy, wild wolf packs to our landscapes.
My colleague cites that there are problems in Wisconsin. There are so many Wisconsinites that speak out, especially the scientists, and some of those scientists are actually economists. Wisconsin economists proved that wolves are protecting human safety. One of the big ways they protect human safety--and they enumerated this--is by reducing vehicle collisions with the deer population, with deer. Other independent research in Wisconsin suggests that chronic wasting disease is suppressed where wolf packs hunt. And there are so many other benefits.
But it is not just his State that this would affect; it would be so many other States.
Look, we have a crisis in our country. We are living through a biodiversity crash. Some people call it the sixth mass extinction. This mass extinction is unique because it is being driven not by natural disasters but primarily by human activity and decision making. Current extinction rates are estimated to be hundreds to thousands of times higher than the normal background rate.
We need to do better for what wildlife remains in our Nation, including the gray wolf. We need to stand up for the role of science in influencing our decisions, for expertise influencing the outcomes, and not harmful legislation like this. That is why I will not allow it to move forward, Mr. President.
