Science writer Heidi Ledford travels to the Hague, centre of political power in the Netherlands and home to the Party for the Animals. She’s shown around the House of Representatives by Marianne Thieme, leader of the party, who describes the resistance to her work, and the terrible impact of factory farming on climate change. She is passionate to represent the voiceless in society: “Once you have them covered, everyone is protected.”

Along with exploring ways in which laws protect animals collectively, Heidi turns to the work of animal rights lawyers who are seeking ways for animals to be considered persons, at which point they stop being ‘things’. She considers Happy, the 48-year-old Asian elephant who lives alone in the Bronx Zoo, who is at the centre of an important case of legal personhood. The hard work has been in the hands of Steven Wise, a non-human animal rights lawyer, who has been working for the recognition of animals as persons for 30 years. Wise draws attention to the fact that many animals meet the criteria of personhood, and must be awarded certain rights and protections or the rest of law becomes a nonsense.
