Can't sleep? You're not alone. A recent report highlights how much sleep we'll lose each year as temperatures continue to rise. Climate change is also drying up water supplies — from North America to East Africa to Europe. We travel the Rhine in Germany where low water levels are killing fish and halting trade. And in Mexico, residents rely on water deliveries due to drought and mismanagement.

This week on Living Planet, we explore a topic that's perfectly natural and something we do every day. Whether you use a squat toilet, a pit latrine or a water closet, humans need to go. But the ways we do so are often not very efficient, useful or good for the environment. So we're taking a look at the history of human excrement and some creative solutions to dispose of and repurpose our waste.

As the climate heats up, we hear about the dry future predicted for one of Scotland's best known exports. We travel to East Africa, where Somalians — desperate for climate aid — are taking the salt out of seawater to solve worrisome water shortages. We also ask how — indeed, if — clean Bitcoin could fix the currency's carbon footprint, and learn how to zap the methane out of cow dung.
