America remembers

Twenty years on from the September 11th attacks, a series of events will be held in New York, Pennsylvania, and Washington DC to commemorate the event.

Also, the Indian government has rolled out tools for online education to help students cope with the COVID-19 pandemic, but with mixed results.

Plus, we discuss a new way to save energy and help the planet's environment, and it involves music.

Joining Julian Worricker to discuss these and other issues are Bahar Dutt, an Indian conservation biologist, author and environmental journalist based in Delhi, and Mark Landler, an American journalist and London bureau chief for the New York Times newspaper.
