Pacific garbage zone, also known as "garbage island". In the Pacific Ocean, the North Pacific circulation system is a relatively stationary area, mainly in the subtropical high zone, where the surroundings of the water flow are brought in, resulting in the accumulation of floating objects and their crushed objects, which are like floating Shaped "waste is called the Pacific garbage belt (block), the Eastern garbage block or the Pacific garbage vortex.
In the long run, many of the drift is biodegradable, and now the circulation system adds a lot of plastic and marine waste. Compared to the biodegradable, plastic class due to light and broken into small pieces, the fragments are still polymer, even broken and then small, still difficult to break down. Some plastic due to light fragmentation, the formation of another pollution, because the floating waste and zooplankton similar to low-level heterotrophic organisms into the food chain after intake. In 2001, for example, a large amount of plastic waste had gone beyond the number of plankton (the main animal in the area), which eventually entered the stomach of seabirds and marine animals.
Over the years, Charles Moore, a marine scientist researcher, has been studying the floating plastic of the North Pacific Circulation System. He mentioned in the article, using salvage with a rectangular opening of 0.9x0.15 square meters. The distribution of plastic material per square kilometer of about 3.34 million, the average weight of about 5.1 kilograms per square kilometer. Trawl depth of about 10 meters found less than half of the actual waste, because the trawl is blocked by diatoms and plankton.
Other information shows that floating garbage blocks are about twice as big as Texas. Researcher Dr. Marcus Eriksen believes that the Pacific garbage block is actually a two-cycle refuse block. Dr. Eriksen said the circulation system was 500 nautical miles outside California, spanning the North Pacific to the coast of Japan.
So plastic recycling such as polystyrene recycling is very necessary to protect our environment. And then we can reuse it to do some other products.
