Mongabay's adventurous Middle East-based staff writer John Cannon just traveled the length of the Pan Borneo Highway and shares what he discovered on the journey about biodiversity, development, and the natural future of this, the world's 3rd largest island.

It took him 3 weeks to travel the route proposed to connect the rainforest-rich Malaysian states of Sabah and Sarawak as well as the Indonesian part of the island of Borneo--to make commerce and travel easier in a region that is notoriously difficult to navigate--and also to encourage tourists to see the states’ cultural treasures and rich wildlife, from elephants to crocodiles, gibbons and clouded leopards.

But scientists warn that the highway is likely to harm the very wildlife it seeks to highlight, by dividing populations and degrading their habitats.

Here's where you can find John's six-part series and his “top 5 revelations from traveling the Pan Borneo Highway" at Mongabay.com.
