Which statement is true regarding macroplastics?

Macroplastics refer to plastic debris that is larger than 5mm in size. These materials can originate from various sources such as packaging, bottles, and other larger plastic items. One of the significant concerns regarding macroplastics is their potential harm to marine life. Macroplastics can entangle sea animals, leading to injury or death, and when ingested, they can cause internal harm or even starvation. Additionally, macroplastics can break down into smaller particles (microplastics) under certain environmental conditions, leading to further complications for marine ecosystems.

The other statements do not accurately describe the characteristics of macroplastics. They are not biodegradable, as plastics are designed to resist decomposition, and while macroplastics are larger than 5mm, they are not defined as smaller. Regarding pharmaceutical use, while plastics in general can be utilized in products within that industry, macroplastics specifically are not generally associated with pharmaceuticals in a meaningful way.
