Ocean plastics pollution has become global environmental problem. Over 860 metric tons of plastic waste enter ocean every year, plastic is lightweight, convenient, strong and cheap, so it has been dramatically produced and thrown away. Single-use plastic products are more likely to end up in our sea, such as straws, food wrappers. Many marine animals like seabirds or sea turtles die from plastic pollution by eating them. Many plastic in ocean are beaking into small particles, called "microplastics", now researchers estimating 2.3 million tonnes floating in the sea worldwide, it damages marine ecosystem, enters humans food chains causeing disastrous consequences for health. Although people become more aware of hazards from microplastics, but presence of plastic in the ocean is continually increasing, the plastic pollution is still main causes of marie species extinction, health problems, and destruction of ecosystems. Research states by 2050, plastic will likely outweigh all fish in the sea. In the last ten years, we have produced more plastics than in the previous century. Plastic takes between 500 - 1000 years to degrade. Microplastics are even unable to fully degrade and exit forever. Today, plastics are being produced at its highest, there are only about 10% can be recycled, the rest is either incinerated or ends up in our sea or our environment. In marine debris, 80% are plastic waste, so improvement plans to save plastic pollution are impelled by internatinal organization one after another recent years. Our governemnt also impelled coastal cleanup program in 2019, the purpose is to let 1,988 kiometers coastline to be managed by volunteers organizaton and individuals to reduce ocean plastic waste.
