Macroplastics in the Surface Ocean is a metric that quantifies the estimated amount of larger-scale plastic debris (greater than 5mm in size) present in the world’s ocean surfaces. This data is critical as it provides a snapshot of the extent of ocean pollution due to plastics, which has significant implications for marine ecosystems, biodiversity, and human health. It aids in understanding the severity of the plastic pollution issue over time and assists in planning and evaluating the effectiveness of plastic waste management and pollution control strategies.Macroplastics can cause physical harm to animals, especially marine life. Sea creatures such as turtles, dolphins, and birds can become entangled in larger pieces of plastic waste, leading to injury or death. Larger marine animals may mistakenly eat macroplastics, mistaking them for food. This can cause blockages in their digestive tracts, leading to starvation and death.
