Peregrine falcon couple hatches a family atop University of Michigan Hospitals

That is just so cool. Showing my age here but I remember as a kid that the pesticide DDT (which we were solemnly told was safe enough to sprinkle over your breakfast cereal) was in wide use. And as a result the larger birds esp. raptors had problems with their eggs not hatching and so forth. And now few decades later after DDT's use was banned comes this! Cool. Nature can repair itself quite nicely if we but let it.
