What type of jobs affect the environment?

Nearly all, directly or indirectly. Directly includes farmers, fishermen, miners, oil workers, chemical workers, builders. Less directly factory workers, pilots, train and vehicle drivers, soldiers. Indirectly anyone who works in a heated or air conditioned office, drives to work, eats a beef sandwich for lunch, uses any machine at work So that leaves window cleaners, traffic wardens, lollipop ladies and gardeners.
