Sai cosa sono veramente i coralli? Sebbene coprano una minuscola porzione degli oceani, le barriere coralline ospitano più del 25% delle specie marine, il bleaching (lo sbiancamento dei coralli) e la loro scomparsa rappresentano quindi uno dei principali pericoli per la biodiversità. Ma come avviene questo fenomeno? E come possiamo fermarlo? Ce lo spiega Lara in questo video.
