The Natural Resources Defense Council (NRDC) has released a map of natural regions around the United States that highlight how the country has evolved over time.

It’s a map that looks a lot like the one we see in the National Geographic series.

The NRDC also released its own map of the world.

It looks a little different, but it’s still pretty accurate.

The map below shows how natural regions have evolved since 1800.

It was made by comparing population density of each natural region, which is a measure of how many people live in each region.

The Natural Resources Deficit Tracker The Natural Resource Deficit Trackers database lists the US federal government’s spending on natural resource development, research and development, and infrastructure.

The report was based on the latest figures from the US Geological Survey (USGS).
