Choose five nations (including the United States) from the enormous database by clicking the corresponding boxes. For "select variables", choose these three: 1. Under "Water Resources" choose "Total Renewable Water Resources" and within that choose only "Total Renewable Water Resources per Capita. 2. Choose "Water Use" and then "Pressure on Water Resources" . Within that subset choose only"SDG 6.4.2 Water Stress". "SDG" means the Sustainable Development Goal. This value is the percentage of total available water that is used by a nation. 3. Under "Water Use" choose "Water Withdrawal by Sector", and within that choose only "Total Water Withdrawal per Capita". Nation Resources per Capita Withdrawal per Capita % Water Stress: withdrawal vs. resources) Step 2. Based…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.
