Brief Summary   This study is a prospective cross-sectional study being conducted to understand the relationship between climate change perceptions, existential nihilism, and pro-environmental behaviour among young adults. It is hypothesised that higher climate change perceptions and lower existential nihilism will correlate to higher pro-environmental behaviour. The outcome variables will be assessed by administering validated scales, which include the Clmate Change Perceptions Scale, Existential Nihilism Scale, and Pro-Environmental Behavior Scale. The scales will be sent out to the participants through Google Forms.
