Could you imagine your life without your iPod, mobile phone or computer games? What would dad say if he had to do without his morning espressos? Or what would mum do if she had to give up her washing machine? In the reality show Yotta the lives of three families are turned upside down as they compete with each other to make the world a better place. Led by their twelve or eleven-year-old team captains, the families search for the best solutions to save the most.
