What is the predominant color in North America?

Complete these three tasks.
Scientists with the Wildlife Conservation Society and Columbia University’s Human Footprint Project mapped degrees of human influence over every square kilometer of Earth’s surface (1 square kilometer = .39 square mile). Four factors were evaluated: population, travel routes, land use, and lights. While humans affect Earth in many ways, these four have the most immediate impact on wildlife and wild lands.
#1) Explore the National Geographic Human Footprint Map
Click on this link: National Geographic Human Footprint Map
You will be taken to this map:
Notice that it already has five layers: Human footprint, Population density, global time zones, land cover, and political boundaries.Green signifies areas least impacted by humans. Each layer tab has a slider bar so that you can make it appear on the map (less transparency) or disappear (greater transparency). Zoom out so you can see the whole globe and play around with the transparencies of the various map layers ( you can even add layers, if you are interested).
Play special attention to the relationship between the human footprint and population density. Try zooming into LA.
#2) Post a substantive discussion of what you saw and what you learned (100 words min). Use these questions as a prompt.
What level of impact does it signify?Do you notice any patterns of human impact, such as greater human impact near urban areas?What color is Los Angeles on the map? How great is the human impact?
What areas are less impacted by human activity? Why do you think these areas are less affected- think about areas of less impact and geographic factors such as climate or physical landscape. Will areas with lower degrees of human impact remain this way? Which factors are likely to change over time? (Each factor could increase, decrease, or remain unchanged over time.)
In which areas is the degree of human impact greater? What connections can you make between areas of greater impact and geographic factors such as climate or physical landscape? Compare the Human Footprint map to the Populations Density map- Do you notice any similarities or differences? What does this data suggest to you?
How might anthropologists contribute to our understanding of these issues and/or solutions to these problems?
#3) Reply to ONE peer with a substantive comment (75 word min).
