I can give an example. My parents live in the UK, and their house was built in 1985. A couple of years ago the copper phone line had to be replaced as it had degraded somebow. The operator had to dig up and reinstall their driveway, brick pathway and garden. Now the operator is installing fibre to replace copper phone lines, so again they need to dig it up.

One days work for one house. Multiply that across an entire nation, and work out how much diesel is burned for that. Where they live you can't get cable (not very common in the UK), but if it was available I guess there would have been another digging day in the 90s.
