Roads vs. the Environment: Where the 'Conflict Zones' Are
"Road Map" shows where economic benefits from roads are as high as the danger they pose to the environment.
About 15 million miles of paved roads are likely to be put down by 2050. That's a lot—it's about 600 times the earth's circumference.
Most of the current road construction is happening in developing countries. But even in developed countries, there are some places where where adding more roads could really help economically. On the flip side, road construction in some of these regions could mean the death of natural biodiversity.
