- Which of the following approaches would be the most effective way to reduce greenhouse carbon dioxide? Increase waste deposition into the deep ocean Plant more environmentally-suitable plants Increase use of fuel sources that do not produce carbon dioxide as a by-product Decrease livestock agriculture.Scientists at the Global Footprint Network calculate the energycomponent of our ecological footprint by estimating the amountof ecologically productive land and sea required to absorb thecarbon released from fossil fuel combustion. This translates into4.9 ha of the average American’s 7.2-ha ecological footprint.Another way to think about our footprint, however, is to estimatehow much land would be needed to grow biomass with anenergy content equal to that of the fossil fuel we burn.Assume that you are an average American who burns about6.3 metric tons of oil-equivalent in fossil fuels each year andthat average terrestrial net primary productivity (p. 32) can beexpressedas 0.0037 metric tons/ha/year. Calculate how manyhectares of land it would take to supply our fuel use by presentdayphotosynthetic production. Compare the energy component of your ecological footprintcalculated in this way with the 4.9 ha calculated usingthe method of the Global Footprint Network. Explainwhy results from…A family travels from New York City to Costa Rica three times a year for a vacation. The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2. Calculate the mass of carbon, in kilograms, that is emitted by the family as a result of their round-trip flights to Costa Rica each year. 3. Calculate the number of acres of forest that must be…
- The carbon footprint is the amount of GHG produced from an activity or a product. What would be the carbon footprint of a power plant producing electricity from coal. Calculate the GHG emission of CO2 per kWh of electricity produced. Assume the energy efficiency of the power plant as 38% and the heating value of coal as 4500 Kcal/Kg. Assume coal is 50% carbon. The answer you will get is also known as the emission factor for a coal power plant.Explain why this carbon cycle diagram does not have a b arrow that shows carbon atoms going from co2 molecules in the air directly to the giraffe. explaon why there is no arrow that shows carbon atoms going from the soil to the tree 4 sentences max for each answerThere is a manufacturing plant that emits 10 tonnes of carbon annually. If this manufacturer were to reduce their annual carbon emissions by 1 tonne it would cost (marginal cost) them $5 dollars, by 2 tonnes it would cost them $10, by 3 tonnes it would cost them $15 and 4 tonnes would cost them $20. If there is a carbon tax of $10 per tonne of carbon, how much would the manufacturer likely reduce their carbon emissions by? a. 1 tonne b. 2 tonnes c. 3 tonnes d. 4 tonnes

- estimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 KgBackground: One of the main drivers of climate change is the emissions of carbon dioxide gas into the atmosphere from the burning of fossil fuels. This has altered the global carbon cycle. using the link below to watch https://youtu.be/xk11DVaAjEA PROMPT: 1) What role does photosynthesis paly in the global carbon cycle? 2) What are fossil fuels and how are they altering the global carbon cycle? 3. Learn about carbon sequestration. Briefly explain what it is and how it can help to mitigate the impacts of climate change. Post a link an example of where/how this is being implemented.Calculate respiration and gross primary productivity for Lake Hugo?
