Rats gnaw on roots, put trees on Kolkata stretch at risk
An army of rats that has dug burrows under the pavements of Harish Mukherjee Road is believed to have weakened the roots of the giant deodar tree — 65ft tall — that collapsed on a passing car, injuring two passengers, last week. The rodents have gnawed into the roots of several other trees along the road that have been left wobbly, according to the civic authorities and locals.
