​​This image of an emaciated polar bear on a barren Arctic tundra sparked a global conversation about the climate crisis. But the photographer who took it says we need more than one catalytic moment to fuel collective action to save the planet.
emaciated [iˈmeɪ.si.eɪ.tɪd]- very thin and weak, usually because of illness or extreme hunger:

barren [ˈbær.ən] - unable to produce plants or fruit:

catalytic - causing things to happen or increasing the speed at which things happen.
