Many families use a lot of thing or do a lot of things like traveling, food, shopping, and buying homes in this century, then all of these things cause carbon dioxide levels to rise. When I calculated the carbon footprint the highest area of carbon was travel because of how much gas my family uses and the miles per gallon and per year my family uses gas. In the food area was the lowest area because the average household in Durham, North Carolina 27713 with 5 people and similar income. When I total up all my household’s total carbon footprint for a year I have 56.8 tons of carbon dioxide each year, and this is not much better than the average household in Durham. If you would want to lower your carbon footprint you would need to lower your gas averages per year or month and use less of these items then you would make your number go down.
