Nat Geo Mapmaker InformationPopulation Density-This map shows population density around the world. Population density describes the number of individuals occupying an area in relation to the size of that area.CO2 Emissions- This map layer shows carbon dioxide emissions for each country, averaged over the years 2006-2010. The data is displayed per capita, meaning per person, in metric tons. Gross Domestic Product- This map layer shows the GDP (gross domestic product) of countries for 2012 in current US dollars. GDP is one way to measure the size of a country’s economy. GDP is a measure of the total value of all goods and services produced in a country during a specific time period.Gross National Income per Capita- This map layer shows the GNI (gross national income) per capita. GNI is an economic measure of the total value of goods and services a country produces, divided by the number of people in the country. Unlike GDP, GNI includes goods and services earned by a country’s citizens abroad. Human Footprint- This map shows the global human footprint. “Human footprint” is a phrase used to describe the environmental impact humans have had on Earth’s surface. Human progress and development have permanently altered ecosystems around the world. Few areas have not been affected by human activity.Questions: Answer using complete sentences.How does GDP differ from GNI? ________________________________________________________________________________________________________________________________________________________________________What is the relationship between “human footprint” and an “ecological footprint”?________________________________________________________________________________________________________________________________________________________________________Directions: Go to the mapmaker website.

This is evident India and China. Australia and Russia have low populations and a minimal footprint. The USA is an exception. It has large human footprint, but a smaller population. Generally, each person requires some basic resources to survive. Therefore, the greater # of people, the more resources needed.Also, the higher the GNI, the larger the CO2 emissions. Developed nations tend to have higher GNI (hence, more money) and consume more fossil fuels and release more CO2 into the atmosphere. More developed nations enjoy a higher standard of living which consumes more energy. ................
