The mass consumption and accelerated discard of human-made products is posing an acute disposal problem at a global scale, and the ocean is the sink for much of our waste. In MALUCA Lab, we generate science-based knowledge to underpin the decision making in the face of the environmental and social challenges posed by the accumulation of litter. Where and when litter accumulations appear?. Which products are the most harmful?. How marine life and ecosystems are affected?. How effective are the actions being taken to combat marine litter?.
