Max Pearson presents a collection of this week’s Witness History episodes from the BBC World Service.

We’re going wild for animals this week. We find out how the Ibadan Zoo became one of Nigeria’s biggest tourist attractions during the 1970s. Our guest Harriet Ritvo, professor of history at MIT, looks back across the centuries to reveal the fascination that humans have always had for animals. And more on the environmental campaigner who became known as Lady Tarzan for her fight against illegal logging in the forests of India.

Plus, we hear from a journalist tortured in Iran's notorious Evin Prison in the wake of the 2009 protests against the Islamic regime. Also, why hundreds of thousands of Moroccans were ordered into the Spanish Sahara by their king. And finally, more on the Bolivian president who went on hunger strike to try to save his country.
