Chris Packham tackles wildlife crime, vertical farming, live animal transport, Stepney city farm

Wildlife presenter Chris Packham starts a new venture - a non-profit company to bring prosecutions against wildlife crime. We ask him what sort of cases the group will bring.
We visit Europe’s biggest vertical farm in Lincolnshire, which has 5,000 square meters of growing space arranged in racks rising to the height of 11m, and producing up to 420 tonnes of leafy greens per year.
The British Veterinary Association is calling for a complete review of how live animals are transported, within the UK and abroad. We hear from BVA president, Simon Doherty.
Our reporter Howard Shannon has been to Stepney City Farm in East London, which benefited from a compulsory land purchase linked to the construction of Crossrail.

Presented by Anna Hill and produced by Beatrice Fenton.
