According to the UN, it is predicted that the human population could reach ten billion people by the year 2050. For broadcaster and naturalist Chris Packham, who has dedicated his life to championing the natural world, the subject of our growing population and the impact it is having on our planet is one of the most vital – and often overlooked – topics of discussion in an era of increasing environmental awareness. Chris is worried that a world of ten billion may simply be too many people for the earth to sustain, given the impact 7.7 billion humans are already having. Travelling around the globe in search of answers to difficult and sometimes controversial questions, Chris investigates why our population is growing so rapidly, what impact it is having on the natural world, and whether there is anything that can be done. Chris travels to Brazil to discover a megacity on the verge of running out of water and an industry expanding to feed our growing numbers – with dire consequences for biodiversity. In Nigeria, a country set to become the third most populous nation on earth by 2050, overtaking the United States, Chris visits an extraordinary community surviving against the odds and a school that might hold the answer to a future fall in the birth rate. Back home in Britain, Chris interviews Sir David Attenborough – like Chris, he is a patron of the charity Population Matters. Chris also examines the role of falling birth rates around the world, the impact of an aging population, and meets a couple who are struggling to get pregnant through IVF. With interviews from several population experts, Chris's focus ultimately turns to the impact our levels of consumption are already having, and asks whether the world can rebalance to accommodate the needs of over two billion more people.

Explores the revolutionary life of one of the 18th century's most consequential and compelling personalities, whose work and words unlocked the mystery of electricity and helped create the United States. Franklin's 84 years (1706-1790) spanned an epoch of momentous change in science, technology, literature, politics, and government — fields he himself advanced through a lifelong commitment to societal and self-improvement. Chapter 1: Join or Die (1706-1774) Leaving behind his Boston childhood, Benjamin Franklin reinvents himself in Philadelphia where he builds a printing empire and a new life with his wife, Deborah. Turning to science, Franklin's lightning rod and experiments in electricity earn him worldwide fame. After entering politics, he spends years in London trying to keep Britain and America together as his own family starts to come apart. Chapter 2: An American (1775-1790) Benjamin Franklin leaves London and returns to wartime Philadelphia where he joins Congress and helps Thomas Jefferson craft the Declaration of Independence. In Paris, he wins French support for the American Revolution then negotiates a peace treaty with Britain. He spends his last years in the new United States, working on the Constitution and unsuccessfully promoting the abolition of slavery.

Against all odds, African-American chemist Percy Julian became one of the great scientists of the 20th century. The grandson of Alabama slaves, Percy Julian met with every possible barrier in a deeply segregated America. He was a man of genius, devotion, and determination. As a black man he was also an outsider, fighting to make a place for himself in a profession and country divided by bigotry—a man who would eventually find freedom in the laboratory. By the time of his death, Julian had risen to the highest levels of scientific and personal achievement, overcoming countless obstacles to become a world-class scientist, a self-made millionaire, and a civil-rights pioneer.
