Â鶹¹ÙÍøÊ×Ò³Èë¿Ú

Max Pearson presents a collection of this week’s Witness History episodes from the Â鶹¹ÙÍøÊ×Ò³Èë¿Ú World Service.

We hear about Cyberia - the first commercial internet café which opened in London in 1994. Director of the Oxford Internet Institute at the University of Oxford, Professor Vicki Nash, talks us through other notable landmarks in the internet’s history. Plus how the Covid N95 mask was invented by a scientist from Taiwan in 1992.

Also how Brazilian theologian Leonardo Boff was punished for his writing on liberation theology. Staying with Brazil, we hear how poor rural workers occupied land owned by the rich, resulting in violent clashes in 1980.

And the world's first global seed vault, buried deep inside a mountain on an Arctic island.
