Tackling the plastic problem: A review on perceptions, behaviors, and interventions.

Area of Science:

• Environmental Science
• Social Science
• Human Behavior Studies

Background:

• Excessive plastic production and consumption pose significant environmental and human health risks.
• Technical solutions alone are insufficient to address the global plastic challenge.
• Understanding human behavior is critical for effective plastic reduction strategies.

Purpose of the Study:

• To review existing social-scientific literature on plastic consumption behavior.
• To identify factors influencing plastic usage and awareness.
• To explore potential intervention strategies for reducing plastic consumption.

Main Methods:

• A comprehensive literature review of 187 social-scientific studies.
• Analysis of research on risk awareness, consumer preferences, and behavioral predictors.
• Examination of political and psychological intervention strategies.

Main Results:

• Despite awareness of plastic's problems, people continue to use it extensively.
• Habits, social norms, and situational factors are key predictors of plastic consumption.
• Political and psychological interventions show potential but often have uncertain long-term effects.

Conclusions:

• Behavior-based solutions are essential for reducing plastic consumption.
• Future research should integrate interdisciplinary approaches and consider cultural variations.
• Interventions need to address the complex interplay of individual behavior and societal factors.
