Simon Reeve presents a travel documentary as embarks on a journey along the Tropic of Capricorn, the line of latitude which cuts through Southern Africa, Australia and South America.

In the four-part BBC2 series Tropic of Capricorn, broadcast in 2008, Simon followed the southern border of the tropics region around the world.

While filming Tropic of Capricorn, Simon traveled through Namibia, Botswana, South Africa, Mozambique, Madagascar, Western Australia, the Northern Territory, Queensland, Chile, Argentina, Paraguay and Brazil.

The journey took him to stunning areas of the world, but it was also a chance for spontaneous discoveries about the changing global environment, poverty, globalisation, AIDS, the rise of the Chinese economy and the suffering of Africa.
