1 . Walking along any beach in the world, you will find plastic of some kind on the shoreline, offering a reminder of the throwaway culture of the present day world. Now, a study has sounded a fresh warning on the damage caused to the marine (海洋的) ecosystem due to plastics, which eventually has an effect on human health due to the seafood we eat

In a paper titled “A Growing Plastic Smog”, researchers called on governments around the world to take firm action to handle the “plastic pollution” of the world's oceans.

The plastics break down over time into minute particles(微小颗粒) that cannot be seen by eyes, but find their way into the ocean ecosystem and into the seafood humans consume. “Microplastics are a problem because they are mistaken for food and eaten by small marine animals.” Charlene Trestrail said. “Once eaten, microplastics can damage an animal’s intestines(肠), and give out potentially harmful chemicals inside animals.”

Charlene Trestrail, a researcher at the University of Technology Sydney, said “the study shows just how big the problem is and that much of the blame was placed on the plastics industry for failing to recycle or design for recyclability.”

Paul Harvey, an environmental scientist, said “Globally, we have reached a point where we can no longer ignore the plastic pollution pandemic(流行病) that is infecting our oceans. This research shows us that beach cleanups and citizen science projects that focus on the environmental problems of plastics have little impact on solving the problem.”

Marcus Eriksen, lead author of the study, said that the findings were a “stark warning that we must act now at a global scale”. “Cleanup is useless if we continue to produce plastic at the current/rate, and we have heard about recycling for too long, while the plastic industry refuses any commitments to buy recycled material or design for recyclability. It is time for policymakers, governments and businesses to wake up and take the issue seriously.”
