Asian transport projects may thwart efforts to save world's tigers

WWF report states that infrastructure boom could lead to animals' habitat being carved up, undoing years of progress

Thousands of kilometres of railways and roads planned across Asia risk dismantling progress made to save the world's last tigers, conservationists have warned.

The WWF said an infrastructure boom in coming years will lead to the construction of 11,000km of new transport projects, carving up the big cat's habitats and stopping them from travelling across the huge ranges they need.
