Abstract
We study how information and the salience of the link between biodiversity and zoonotic diseases affects attitudes and behaviour towards biodiversity conservation. Specifically, we investigate the effect of different information provisions on monetary donations for biodiversity conservation as well as on policy views regarding international nature conservation goals.
