Screenshot: The Year Earth Changed Earth Day takes on a whole new resonance in 2021, as the world continues to battle the ongoing Covid-19 pandemic. The theme for this year’s Earth Day (April 22), is Restore the Earth, and it will be put into action through three days worth of digital events starting on April 20, including focusing on climate change, environmental justice, and emerging green technologies. Keeping these issues in mind, Apple TV+ is debuting a brand new original documentary narrated by erstwhile Emmy-winning historian, broadcaster, and orator Sir David Attenborough, called The Year Earth Changed. The documentary will premiere globally on April 16 to herald the world’s largest annual environmental movement.
