대기오염은 수명을 3년 단축시킨다 | BBC 뉴스 리뷰

Air pollution causes the average human life to be three years shorter than it could be, say scientists. Neil and Catherine look at the vocabulary in the news around this story.

The story:

Lung disease, cancer, heart problems and stroke have all been linked to air pollution(대기오염) – particularly man-made emissions(배출) from fossil fuels. Now an international group of researchers has used a new method to model the impact on our health. The team believes pollution led to around 8.8 million premature(너무 이른) deaths in 2015. That represents an average shortening of life expectancy of nearly three years across the global population.

Vocabulary:

​

life expectancy : 기대수명
lifespan : how long someone or something lives 수명

• The elephant’s lifespan is longer in the wild than in zoos. • The lifespan of smartphone batteries is getting better.

​

shorten : make shorter 짧게 하다, 단축하다, 짧아지다

• Smoking shortens lives. • Please shorten my trousers. They are too long.

​

deadlier: more likely to cause death than something else 부사 deadly(치명적인, 치사의)의 비교급

• The plague was deadlier than coronavirus. • Machine guns made WW1 deadlier than previous wars.
