Many old trees being cut down

Newly cut tree stumps, Harrow Road (Sudbury)

Similar scenes noted all around Harrow and Brent. Has there been any justification given? The near one in this picture looks like it was healthy, fairly straight and not causing upheaval. The further one appeared to be hollow. Could it be that those responsible are taking every opportunity to reduce their workload by reducing the number of large, old trees?
