The Fake Trade

Channel 4, 8pm

The worldwide counterfeit trade is worth an estimated $500 billion a year. It's one thing buying a cheap knock-off handbag or an iffy watch, but now there is fake medication for breast cancer on the market and condoms with microscopic holes that are sold in Africa. Fakes are said to be responsible for 8 per cent of China's booming economy. The foreign multinationals are reluctant to kick up a fuss because they rely on cheap Chinese labour in the first place. People smugglers now use illegal immigrants to make and sell fakes to pay for their passage. This two-part series does not provide a focused narrative, but it does give a clear picture of the scale of the problem.

Panorama

BBC One, 8.30pm

Television is good at pointing the camera at problems and making tut-tutting noises, but rarely does it offer practical solutions. Not so tonight. Panorama looks at the nastier forms of antisocial behaviour and asks how victims should respond. Do you confront the perpetrators? Do you move house? Do you turn your neighbourhood into a war zone and your home into a fortress? Do you work through all the official agencies or have a quiet word with the local Tony Soprano? It turns out there is an effective solution. It can never be a panacea as long as poverty and inequality exist, but apparently it does work - and many desperate people who watch this programme may have reason to thank Panorama.

Life in Cold Blood

BBC One, 9pm

The last in this series is also the most magical. David Attenborough focuses on the biggest reptiles alive today - crocodiles, turtles and tortoises. There are wonderful shots of giant Galapagos tortoises, which can weigh up to a quarter of a tonne and live to be 150. More incredible still is the sight of a male turtle trying to mate while six other jealous males bite its fins and try to prevent the amorous pair from surfacing for air. But the most miraculous sight of all is a mother crocodile looking after its babies; first carrying them down to a nursery pool in its mouth and later leading them, Moses-like, across the land to the safety of deep water. Watch this, and you will never feel the same way about crocodiles again.

Stephen Hawking: Master of the Universe

Channel 4, 9pm

In A Brief History of Time, Professor Stephen Hawking said we would soon have a simple and elegant set of laws to explain everything in our Universe. “My life's work,” he says, “has been to unify the theories of the very large and the very small. Only then can we ask the more challenging questions: ‘Why are we here?' and ‘Where did we come from?'” Unfortunately, gravity kept getting in the way. You can't have a theory of everything without first explaining how gravity arose and why it appears to be so weak. The first programme in this accessible two-parter on Hawking's life and work explains the gravity problem. It could be that the Universe is made up of 11 dimensions and we are like fish swimming around in a tank, oblivious to the other dimensions.
