Worries and hopes: climate, the UN, space, AI, and is the world getting better?, sentence 3

There are real stories of fixing things together: countries agreed in 1987 to ban the chemicals eating the ozone layer, and it is slowly healing; solar power became about ten times cheaper in ten years; vaccines for COVID-19 were ready within a year.

Who acts: real stories, countries, chemicals, world, solar power, vaccines · What happens: be, fix, agree, ban, eat, heal · To what, where: 1987, chemicals, ozone layer

This is a sentence of the lesson «Worries and hopes: climate, the UN, space, AI, and is the world getting better?» of the history course of Mova's primary school.
