This paragraph is taken from an English coursebook, from a lesson called "Dangerous Jobs". The entire article is called "Smoke jumper".
I am parachuted into areas where there are forest fires. Once I am there, I have to cut trees down and clear plants to stop the fire spreading. It is risky, because fire and smoke can kill you, but we wear special protective clothes to stop the heat and smoke from affecting us. If we do our job well, we have the satisfaction of saving people’s lives and protecting forests.- "English for Starters - Students' Book" by Julia Starr Keddle & Martyn Hobbs
Why did the author choose to use the passive voice "I am parachuted" instead of the active voice "I parachute" in this context?
