Lesson 6: Food Choices and Climate Change


Students will review concepts of the energy pyramid focusing on the loss of usable energy as it moves through food chains from producers to consumers. These ideas will then be used to explain pricing variations relative to vegetables and meats. Because more land is required to support a pound of animal vs. a pound of plants and there are limits to land that can be used for agriculture, the importance of food choice will be explored. As a concluding activity, students will calculate the distance that food ingredients for a standard lunch. In this way, students will also account for the added fossil fuels used in agriculture to provide cities with food.
