The construction of modern interstates and other highways have been wonderful for helping people travel to places they would otherwise not be able to see. But these highways have been deadly for millions of wild animals whose ancestors have been traveling their own paths for countless generations. Now many people have been investing in bridges and tunnels for wildlife to be able to safely cross even the busiest of thoroughfares. This is a small step for humans to recognize the needs of the others with whom we share the planet.
