FILE - In this Wednesday, Sept. 24, 2014, file photo, a technician releases mosquitoes that are infected with a dengue-blocking bacteria called "Wolbachia" in the Tubiacanga neighborhood of Rio de Janeiro, Brazil. The nonprofit World Mosquito Program infected mosquitoes with that bacteria, called Wolbachia, and released them in communities in Indonesia, Vietnam, Brazil and Australia that agreed to be test sites. Researchers say dengue cases fell dramatically, compared to nearby communities where regular mosquitoes did the biting. (AP Photo/Silvia Izquierdo, File)

FILE - This undated file photo provided by the U.S. Geological Survey shows a side view of a recently emerged adult female western glacier stonefly from below Grinnell Glacier in Glacier National Park, Mont. The continued existence of two species of insects is in doubt because climate change is melting away the glaciers and year-round snowfields they depend on, U.S. wildlife officials said Wednesday, Nov. 20, 2019. The western glacier stonefly and the meltwater lednian stonefly found in the northern Rocky Mountains will be protected as threatened species under the federal Endangered Species Act. U.S. Fish and Wildlife Service officials said. (Joe Giersch/U.S. Geological Survey via AP, File)

According to a study released on Thursday, Sept. 19, 2019, North America’s skies are lonelier and quieter as nearly 3 billion fewer wild birds soar in the air than in 1970. Some of the most common and recognizable birds are taking the biggest hits, even though they are not near disappearing yet. The population of eastern meadowlarks has shriveled by more than three-quarters with the western meadowlark nearly as hard hit. (AP Photo/David Zalubowski, File)
