The formula for calculating people’s environmental footprint

Read the text to answer question.

     The formula for calculating people’s environmental footprint is simple, but widely misunderstood: Impact = Population x Affluence x Technology (I = PAT). The global rate of consumption growth, before the pandemic, was 3% a year. Population growth is 1%. Some people assume this means that the rise in population bears one-third of the responsibility for increased consumption. But population growth is overwhelmingly concentrated among the world’s poorest people, who have scarcely any A or T to multiply their P.

     Yet it is widely used as a blanket explanation of environment breakdown. Panic about population growth enables the people most responsible for the impacts of rising consumption (the affluent) to blame those who are least responsible.
