This week we talk to Dr Matthew Currell about how manufacturing in China has led to unprecedented water pollution throughout thw entire country. This is now causing widespread health effects including a phenomenon known as cancer villages - which are small communities in China close to polluting factories where cancer rates are far above the national average. You can read more about the water pollution crisis in Dr Currell's publications; The Global Drain: Why China's Water Pollution Problems Should Matter to the Rest of the World and about the problems China faces in combating this issue in Deep challenges for China's war on water pollution. And if you want to learn more about what corporations are doing to clean up their manufacturing practises in China, you can find reports through the Institute of Public & Environmental Affairs.

Also this week one for the chocolate lovers. Everyone knows we need bees to pollinate our favourite fruit and vegetable plants. But did you know chocolate is actually pollinated by sandflies, or midges? We talk to Samantha Forbes about her research which looks at ways to increase midgie populations and in turn increase chocolate yield in northern Australia. 

And Manisha delivers her second tip on how to keep those new years resolutions strong using science. This time using the if-then planning technique to change your habits and kick some goals.
