The Passive Voice
We use the passive when the action itself matters more than who or what does it — very common in reports about problems, like the one in this chapter.
RULE
Form: be + past participle (the tense of be changes, the past participle never does)
The 'doer' of the action can be added with by — often left out completely when it's unknown, obvious, or unimportant
TIP
In this chapter, the habitat is the focus, not the people clearing it — that's exactly when English prefers the passive.
EXAMPLES
  • Active: 'People are clearing the forests.'→ Passive: 'The forests are being cleared.'
  • Active: 'They are reducing the koala's habitat.'→ Passive: 'The koala's habitat is being reduced.'
  • Active: 'People have done an enormous amount of damage.'→ Passive: 'An enormous amount of damage has been done.'
  • Active: 'National legislation does not protect the habitat adequately.'→ Passive: 'The habitat is not adequately protected by national legislation.'
