A growing global population, means we are facing a considerable housing shortage and it has been estimated that by 2025, as many as 1.6 billion individuals will face crowded substandard housing. But, the need to build more homes comes at a cost as in countries like the U.K., half of the population's carbon emissions come just from the buildings we inhabit.

If you've followed environmental stories over the years, you'll know this tune. Scientists have long been singing off the same songbook when it comes to fossil fuels, deforestation and pollution. But drum not often banged is the dwindling supply of phosphorus. It's is an essential element for all life. It makes up our DNA and all organisms need it for energy. It cannot be replaced, there is no synthetic substitute. In other words, without phosphorus, there is no life. This week on the Naked Scientists, we investigate whether we're running out of phosphorus for fertiliser and what we can do about it by getting ourselves knee deep in human sewage... Plus in the news, we'll learning how to hide a secret message with a fizzy drink, we'll be getting up close and personal with the cuddle chemical oxytocin and why Monday's Mercury transit was so exciting!
