Fauci: 'We've got to do something' about the coronavirus numbers

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, sees COVID-19 as a formidable, global foe. But he tells The World's host Marco Werman he's cautiously optimistic there will be more than one safe and effective vaccine available. Also, could pulling CO2 directly out of the air be an effective way to fight climate change? Plus, in Brazil, wildfires in the Amazon are threatening a region already hit hard by the novel coronavirus. And, the next Women's World Cup will be hosted by Australia and New Zealand. The 2019 soccer FIFA World Cup was a smashing success, with well over a billion viewers. Expectations are high for 2023.
