Rewilding To Save Our World
We need to accelerate the migration of people to urban areas, surrounded by a circle of farms, and then leave the rest to the wild animals:
The World Needs Wolves - Mary Ellen Hannibal via NYTimes.com
Around the planet, large predators are becoming extinct at faster rates than other species. And losing top predators has an outsize effect on the rate of loss of many other species below them on the food chain as well as on the plant life that is so important to the balance of our ecosystems.
So what can be done? For one thing, we have begun to realize that parks like Yellowstone are not the most effective means of conservation. Putting a boundary around an expanse of wilderness is an intuitive idea not borne out by the science. Many top predators must travel enormous distances to find mates and keep populations from becoming inbred. No national park is big enough for wolves, for example. Instead, conservation must be done on a continental scale. We can still erect our human boundaries — around cities and towns, mines and oil fields — but in order to sustain a healthy ecosystem, we need to build in connections so that top predators can move from one wild place to another.
Many biologists have warned that we are approaching another mass extinction. The wolf is still endangered and should be protected in its own right. But we should also recognize that bringing all the planet’s threatened and endangered species back to healthy numbers — as well as mitigating the effects of climate change — means keeping top predators around.
Or, put differently, take ourselves out of the role of top predator.
