27 The Problem Is Real

28 Carbon in Living Trees Years Since Abandonment Indoor Alternative: Grow plants in pots, dry them in an oven, weigh them and divide by 2. This yields the carbon that came from the atmosphere. Multiply by 44/12 and you have the total mass of CO 2 that was taken from the atmosphere.

29 On average a US citizen produces roughly 20 tons! of CO 2 The CO 2 that comes from your tailpipe weighs 3 times as much as the gasoline you put in. The global average per capita production of CO 2 is only 4 tons. Personal carbon accounting. How much greenhouse gas is produced by your family’s car, by heating your house, by the electricity your family uses, by your school, etc.? How much do people in other cultures produce? To prevent dangerous global warming, global production of CO 2 must stabilize through 2050, and this means that US consumption must drop as other societies industrialize.
