Enhancing marine citizenship as a strategy to promote the reduction of single-use plastics consumption in different cultures
AI summary Read the abstract
Researchers studied single-use plastic (SUP) consumption behaviors and the concept of 'marine citizenship' — personal responsibility for ocean health — across different national cultures to evaluate whether promoting marine citizenship can reduce SUP use and drive adoption of sustainable alternatives. The study examined how cultural context shapes the effectiveness of marine citizenship-based intervention strategies for reducing plastic pollution at the consumer level.
Single-use plastics (SUP) coming from the land represent a large fraction of marine plastic debris that threatens the ocean biota today and are one of the main causes of microplastic pollution. Consumer behavior is essential to stop the use and improper disposal of SUP, replacing plastic with alternative eco-friendly products. For the evident plastic pollution of beaches and seas, marine citizenship, interpreted as the personal responsibility that individuals take for the oceans, could help to reduce SUP use and change to sustainable alternatives. Here we studied SUP consumption behaviors in Spain ( n = 585) and Mexico ( n = 337) using a multivariate multiple regression approach. Different policies and social norms in the two countries were reflected in reduced SUP use in Mexico compared to Spain and more recycling in Spain than in Mexico. The main reasons for the use of SUP were the lack of alternatives and forgetting reusable goods in the two countries. Feeling responsible for the ocean predicted the intention to use eco-friendly alternatives, while sea frequentation predicted recycling. Gender, age, and education influenced significantly the willingness to use eco-friendly alternatives. From the results of this study, campaigns promoting awareness through increased ocean literacy and marine citizenship—even in regions far from the sea—could promote reductions in SUP consumption, enhancing the use of sustainable alternatives. Those campaigns could be tailored by country, taking into account local policies and habits, gender, age, and educational levels.

Sea of plastic: representations of the sea and pro-environmental attitudes and behaviors regarding marine plastic pollution in Peru and Chile
AI summary Read the abstract
Researchers explored pro-environmental attitudes and behaviors regarding marine plastic pollution through 44 semi-structured interviews with Peruvian and Chilean citizens, examining how sea-related representations shape environmental engagement. The study found that positive connections to the sea were associated with stronger motivation to reduce plastic pollution.
The significance of global identity in shaping individual behaviour and policy support: Focus on plastic purchasing and consumption
AI summary Read the abstract
A survey of 2,400 Japanese adults found that people who felt a stronger sense of belonging to a global community were more likely to recognize plastic pollution's harms, feel responsible, and reduce plastic purchases. This sense of global identity also predicted support for plastic-related government policies.
On the way to reduce marine microplastics pollution. Research landscape of psychosocial drivers
AI summary Read the abstract
A review of psychosocial drivers of marine plastic pollution found that factors including consumer convenience preferences, low perceived personal responsibility, and weak norm activation explain why behavioral change around plastic use is slow, and that interventions combining social norms messaging with structural changes show the most promise.
Human Perceptions and Behaviour Determine Aquatic Plastic Pollution
AI summary Read the abstract
Researchers examined how human behavior and decision-making at every stage of the plastic lifecycle — from production and consumption to disposal — ultimately drives aquatic plastic pollution, arguing that lasting solutions require behavioral change across all sectors rather than purely technological fixes.
