When visiting the Navajo Nation, it's not hard to notice the large number of dogs roaming the rural region. There’s currently an estimated 250,000 stray animals. But, that could be changing. Today on the news, a report on a pop-up animal clinic on the reservation. Plus, a new study finds that low-producing oil and gas wells make up about half of the methane emitted from all well sites in the US. And, a report on plans to monitor oil and gas wells using airships.
