Photographer Joel Sartore on De-Extinction CBS Sunday Morning. Joel Sartore is one of my favorite photographers. Most of his work is produced for National Geographic but now and again he shows up on another favorite of mine, CBS Sunday Morning. This past Sunday’s show highlighted the ongoing issue of species going extinct. I had never realized that the passenger pigeons were numbered in the BILLIONS before they went extinct in the early 1900’s. Billions! I thought the near total elimination of 65 million American Bison was a huge number. Take a few moments to watch Joel’s segment below. He highlights a project scientists are working on called de-extinction. They’re actually working on recreating a passenger pigeon. Kind of Jurassic Park-like science and extremely interesting. Any thoughts on all of this? Should we be messing with nature to the point of rebuilding an extinct species. Joel has some great thoughts on this. Let us know what you think in the comments below. I’m not sure how I feel.
