Chaman's response to the trees in the capital being infected with cancer: With this air pollution, there is no solution other than cutting down the diseased trees.

The head of the Tehran City Council:

When trees become diseased, especially as they age, there is nothing that can be done. Unfortunately, this volume of smoke and polluted air destroys the trees along the streets.

The municipality has a duty to maintain the trees, but when they become diseased, and especially as they age, nothing can be done. Unfortunately, this level of smoke and polluted air kills the street trees, and the fact that some trees have managed to survive in these conditions is very positive. / ILNA
