Lester Brown talks about topics discussed in his book, Full Planet, Empty Plates. The main topic discussed is how food supply is changing (decreasing), and how we can fix this problem. Mainly, climate change was to blame, as temperature increases decrease crop yields. This climate change is caused by carbon emissions, which have substantially increased as of late. In order to help fix this we need to stabilize the climate situation, get the brakes on population growth, and raise water productivity. If these goals are not met or even attempted, people will no longer be able to afford to eat everyday. This is already a problem now in developing countries. Many people in these countries are having to plan what are called “foodless days” because the price of food (mainly grain, which has doubled in price over the past five years) has increased substantially. The problem of food supply may not seem like a big issue to Americans, however it is us who eat 1600 pounds of food per person per year. When it is taken into account that 500 gallons of water are used to produce the food that Americans eat every day, this problem seems more relevant to those of us who don’t have to go without food. To fix this problem will be hard, but this podcast will help discover why it is important and how to go about it.
