The Earth is facing the biggest mass extinction since the dinosaurs were wiped out. Throughout evolution 99 percent of all species which ever existed have disappeared. However the rates of extinction are now 10,000 times the natural rate. Coming to the rescue are men like Dr Thomas Hildebrandt and his team. This programme follows the pioneers of hands-on animal reproduction as they use cutting-edge science to preserve our planet's fauna for future generations.
