Episode 3

As figures reveal that 2,000 dogs are being stolen in the UK each year, Keeley Donovan speaks to pet detective Colin Butcher to discover what can be done to keep them safe. Paul Martin is in London at the Lordship Rec. He meets Clasford Stirling to hear how the Rec has blossomed and is creating an exciting blueprint for others to follow. The north Devon village of Croyde - like so many other coastal villages all over the UK - is determined to crack down on plastics, and a shocking discovery in a cove graphically illustrates why villagers are enlisting the help of holidaymakers as they descend on the beach in their thousands. Margherita Taylor reports on Croyde campaigners doing their bit to go plastic-free. On the Sussex Downs, Jules Hudson finds out how light pollution is wrecking prospects of romance for glow-worms. He is with scientist Craig Perl on a night-time safari, hoping to spot one of them glowing as they should.
