Sources of Ocean Plastic
Ocean plastic pollution is caused largely by land-based sources. One major contributor is littering and improper disposal of everyday plastic items like bottles and cans, which are easily carried into water bodies. Another significant cause is urban runoff which occurs when rainwater flows over streets, collecting plastic waste and debris, and drains directly into rivers and oceans. Lastly, open landfills near coastlines can leak plastic into the sea due to wind or overflow. Tackling these sources is key to preventing plastic from ever reaching the ocean.
Impact on Marine Life
Plastic pollution severely impacts marine life. Sea turtles, fish, and seabirds often ingest plastic, mistaking it for food, causing starvation and death. Others become trapped in debris, leading to injury or drowning. Habitats like coral reefs and mangroves are destroyed. Microplastics enter the food chain, threatening entire ecosystems and even human health.
The Great Pacific Garbage Patch
The patch is a huge gathering of marine debris, primarily plastic, located in the North Pacific Ocean. It's not a solid landmass but a soup of trash with a high concentration of plastic particles, including microplastics and larger items like fishing nets. We all know “what goes around comes around”, hence this microplastic now is found in the human body through the food cycle. It’s almost three times as big as France. The GPGP is accumulating at an alarming rate.
Community Action
Looking to make a difference in your community? Gather your loved ones—or head out solo—for a cleanup at your local beach. Every piece of trash you pick up helps protect marine life and keeps our oceans healthy. A quick online search for activities in your area is all it takes to create a big splash of support!
