A person's ecological footprint is the total amount of land required to offset a person's carbon emissions. The table below shows ecological footprint data for five different students. Each value is a measure of the number of hectares per land required. Table 1.

The footprint for each individual is based on simple calculations to determine approximate resource use. The footprint uses a top-down approach to provide a complete picture of resource use for comparison between individuals. (C The footprint uses global hectares, rather than hectares, to determine the approximate proportion of Earth's surface needed to support the activities of an individual. D The footprint is a static analysis and does not include all environmental impacts of an individual.

If the ecological footprint per person of a country or theworld is larger than its biological capacity per person toreplenish its renewable resources and absorb the resulting waste products and pollution, the country or theworld is said to have an ecological deficit. If the reverse istrue, the country or the world has an ecological credit orreserve. See Figure 1.11 for a map of the world’s ecologicaldebtor and creditor countries. Use the data to the right tocalculate the ecological deficit or credit for the countrieslisted. (As an example, this value has been calculated andfilled in for the world.)1. Which three countries have the largest ecologicaldeficits? For each of these countries, why do youthink it has a deficit?2. Rank the countries with ecological credits in orderfrom highest to lowest credit. For each country, whydo you think it has an ecological credit?3. Rank all of the countries in order from the largest tothe smallest per capita ecological footprint.
Our air pollution blows into someone else's territory; therefore, it is uneconomical to install pollution controls, because they will bring no direct economic benefit to those who have to pay for them. 1. Are you for economics or the environment and why? Answer the discussion questions thoughtfully, using information from the articles. https://blogs.wsj.com/chinarealtime/2013/01/30/chinas-air-pollution-problem-whose-responsibility/ https://www.nationalgeographic.com/environment/global-warming/pollution/

1. Let's take a brief look at ecological footprints on the national level. This is important, because each nation has different environmental policies and cultures. Do a comparison of your home country with others around the world using the instructions below. Use this Footprint of Nations website: (http://data.footprintnetwork.org/#/) Use the interactive map showing average ecological footprints for various countries. I recommend you choose the map option showing Ecological Deficit/Reserve. Once you have selected a country, a graph will appear showing the ecological footprint and biocapacity/ natural resource capacity of your selection. What you are determining is how much natural resource capital a nation has vs. how much it is using. List those values in the chart for the most recent year given. Be careful here: Because this is international information (metric system), the units of measure are in hectares, not acres! You can use either measurement but if you use acres you will…
What is the range of values for percentage of emissions from transport of food to retailers (delivery)? Weber and Mathews found that 83% of food’s total emissions came from its production process on the farm or feedlot. What do these numbers tell you about how you might best reduce your own footprint with regard to food?
What do you think is the most important environmental health issue for the world, and why? What is a public health intervention that could help address this issue? (Name and explain.) Minneapolis Minnesota Add the sources as well
A fishprint provides a measure of a country’s fish harvestin terms of area. The unit of area used in fishprint analysisis the global hectare (gha), a unit weighted to reflect therelative ecological productivity of the area fished. Whencompared with the fishing area’s sustainable biocapacity (itsability to provide a stable supply of fish year after year,expressed in terms of yield per area), its fishprint indicateswhether the country’s annual fishing harvest is sustainable. The fishprint and biocapacity are calculated using thefollowing formulas:Fishprint in (gha) = metric tons of fish harvestedper year/productivity in metric tons per hectare ×weighting factorBiocapacity in (gha) = sustained yield of fish in metrictons per year/productivity in metric tons per hectare ×weighting factorThe following graph shows the earth’s total fishprint andbiocapacity between 1950 and 2000. Study it and answerthe following questions: If biologists determine that this country’s sustainedyield of fish is…
