Skip to 0 minutes and 12 secondsHi. My name is Dr. Dan Bebber. And over the next four weeks, my colleagues and I will guide you through some of the huge challenges we face in feeding the growing population healthily and sustainably. Sharing a meal with friends and family is one of the greatest pleasures life can offer. But it's become increasingly clear that the way we produce, process, trade, and consume our food is having serious consequences for our health, society, and environment. The list of dangers we face is long. Globally, some 700 million people remain undernourished, while more than 2 billion of us are overweight and suffering from avoidable health problems. And though many people cannot afford a healthy diet, globally around 1/4 of food is thrown away.

Skip to 0 minutes and 59 secondsFarmers fight continuous battles against virulent pests and diseases of crops and livestock, and face the growing threat of climate change in the form of extreme weather and poor harvests. Intensive agriculture has polluted rivers and oceans, emptied aquifers, eroded and reduced soil fertility, destroyed ecosystems, and reduced biodiversity. Overfishing has brought many species of fish to the brink of extinction. Meanwhile, the global population continues to expand, the consumption of unhealthy and resource-intensive foods grows, and the threat from climate change rises. People around the world are eating increasingly similar diets. And some argue we risk losing the cultural identities that societies have built around food.

Skip to 1 minute and 45 secondsWe rely on international trade for much of our food, which makes us vulnerable to shifts in government policies and shocks to the economy. Experts agree that the food system, the interconnected processes that lead from a planted seed to a meal on the table, requires a revolution to avoid disaster in the near future. But all is not lost. Researchers, policymakers, businesses, communities, producers, and consumers around the world are working on ways to make our food system healthier, and fairer, and more sustainable. You will hear from Exeter University experts on the current state of the food system and the ways we can make it better. To find out more about the contributors, see the biographies which follow this film.

Skip to 2 minutes and 28 secondsYou will have the chance to analyze the issues and debate the possible solutions with fellow students. In the first week we'll consider the effects of changing diets on health, and making the switch to a healthier diet. In week two we'll learn about how production of agricultural crops, livestock, and fish is affecting the environment. In week three we'll tackle three major threats to food production-- climate change, the loss of soils, and destructive pests. In week four we'll investigate the economics and politics of the food system, and the roles of farmers, agri businesses, and governments. I hope you enjoy the course. Help us to rethink food systems for the 21st century.
