Why does it matter?
The impact of microplastics reach far and wide. In the ocean, they damage the biological carbon pump, a natural process where marine organisms like phytoplankton absorb carbon and carry it to the deep sea. On land, they disrupt soil structure, damage microbial life, and reduce plant growth, all of which reduce carbon storage and worsen climate change.
Microplastics are also accelerating biodiversity loss. Marine animals ingest these particles, mistaking them for food, leading to injury, poisoning, and death. Animals often mistake microplastics for food, introducing toxic chemicals into ecosystems, weakening species resilience and disrupting ecological balance. This widespread harm to wildlife, often caused by preventable human activity, raises serious ethical concerns and reflects a disregard for animal welfare, ecosystem health, and the rights of future generations to a liveable planet.
Consequently, microplastics also pose health risks to humans. According to WWF, we’re consuming about a credit card’s worth of plastic each week, raising concerns about long term exposure. Alarmingly, microplastics have been found in 99% of tested seafood, and even in human brain tissue.
