Carbon is essential for both the creation of new life and the sustenance thereof. The carbon dioxide emission factors in this article are expressed in terms of the energy content of coal as pounds of carbon dioxide per million Btu. This is slightly lower than the range of values for arterial blood gases derived from p. 907, Taylor, C., C. Lillis, and P. LeMone, 1989: Fundamentals of Nursing. Industry and power stations are responsible for 50% of the burning of fossil fuels (coal, oil and natural gas) which releases carbon dioxide (CO2) into the atmosphere. Airplanes would be responsible for 2% of the world's emitted carbon dioxide. Top Tips for Reducing your Carbon Footprint 1. them greatly. Acknowledgments. Carbon is an element present in Carbon Dioxide (CO2), which exists molecularly as one part carbon and two parts oxygen. Figure 1b Close-up of GAWS tower. The Lone Star State’s 653.8 million metric tons of carbon dioxide produced in 2016 was more than 80 percent higher than was generated in California, the second-largest producer. Food’s Carbon Footprint: Eat vegetarian. This site unfortunately does not quote a source. = 0.9 kilograms of carbon dioxide for each day per human. The molecular weight for moist air is about 28, which means that the air we inhale contains about, 3.8 x 44 divided by 28 x 10000 = or 0.0006 grams carbon dioxide per gram of air. 1356 pp. Shrink That Footprint’s chart shows that a meat lover has the highest carbon footprint at 3.3 tons of greenhouse gas emissions.A vegan diet has the lowest carbon footprint at just 1.5 tons CO2e (Carbon Dioxide … Our human wouldn’t eat all sugar. 0.038 carbon dioxide molecules per 100 air molecules, or
But the South's facilities this year alone will pump out about 1.2 billion tons of carbon dioxide -- 43 percent of the nation's total emissions of about 2.8 billion tons. Isn’t it exciting that we came up with roughly the same answer! But our human would release carbon in other forms (feces, dried skin, shed hair, etc.) The region has a total of 1,624 power plants, less than 20 percent of the nation's total of 9,190 plants. This tree (I’m assuming this is a big one) is said to take up 21.8 kilograms of carbon dioxide a year. = 11.52 kilograms per day “processed” by breathing, To find out how much carbon dioxide is put into the atmosphere, we compare the amount of carbon dioxide (0.038% by volume) inhaled to the amount (4.6-5.9% by volume exhaled, Reference 3. He/she would eat some fat as well, which has 9 kiloCalories per gram. And, just for fun, I’ll use my respiration rate. And google gave this blog writing (2008!!). But I hear stories from scientists who are measuring carbon dioxide uptake about how they avoid contaminating their measurements. Molecular weight of carbon dioxide (2 x 16 + 12 = 44), This means that:
1. p. 151, Berkow, , R., et al., 1997: The Merck Manuel for Medical Information: Home Edition. I will estimate this in two ways. The Lone Star State has 335 power plants, 81 "red alert" plants, and total CO2 emissions of 290 million tons for this year alone. Similarly, the fractional amount of carbon dioxide exhaled, by mass is, assuming 5% by volume: So the net fractional change in carbon dioxide for each breath is. And our human was exchanging a typical amount of air. So – we are part of the carbon cycle, too! In a … Livestock farming produces from 20% to 50% of all man-made greenhouse gas emissions.. When I measured my respiration, I was sitting, so I’m thinking this is for an average adult at rest. In 2014 there were more than 100,000 flights per day. How does that compare to some other things? Assuming all this carbon is released as part of carbon dioxide, our human releases 733 grams of carbon dioxide (200 grams x 44/12). Finally, if you wanted a more accurate number, how would you change the calculations? Comparison to carbon dioxide uptake by plants. This blog was inspired by activities at the 2008 GLOBE Learning Expedition (GLE) in South Africa. The Argonne National Laboratory “Ask a Scientist” (http://www.newton.dep.anl.gov/askasci/zoo00/zoo00065.htm) lists 5.3 per cent by volume for “alveolar air” in response to a question about how much CO2 is exhaled.
