While “Great Pacific Garbage Patch” is a term often used by the media, it does not paint an accurate picture of the marine debris problem in the North Pacific Ocean. Marine debris concentrates in various regions of the North Pacific, not just in one area. The exact size, content, and location of the “garbage patches” are difficult to accurately predict. The name “Pacific Garbage Patch” is not visible with satellite or aerial photographs. While higher concentrations of litter items can be found in this area, much of the debris is actually small pieces of floating plastic that are not immediately evident to the naked eye. The entire Great Pacific Garbage Patch is bounded by the North Pacific Subtropical Gyre. The circular motion of the gyre draws debris into this stable center, where it becomes trapped. While many different types of trash enter the ocean, plastics make up the majority of marine debris for two reasons. First, plastic’s durability, low cost, and malleability mean that it’s being used in more and more consumer and industrial products. Second, plastic goods do not biodegrade but instead, break down into smaller pieces. It is possible to sail through “garbage patch” areas in the Pacific and see very little or no debris on the water’s surface. Debris found in any region of the ocean can easily be ingested by marine species causing choking, starvation, and other impairments. Cleaning up marine debris is not as easy as it sounds. Many microplastics are the same size as small sea animals, so nets designed to scoop up trash would catch these creatures as well. Even if we could design nets that would just catch garbage, the size of the oceans makes this job far too time-consuming to consider. Besides, it is not likely that any country will pay the expensive bill.

太棒了，你精準抓到了這篇文章的核心主旨，這題答得非常好！在地方特考的英文閱讀測驗中，主旨題（main idea）經常考驗考生統整段落資訊的能力，而不僅僅是抓取片段單字。你能成功選出正確答案，代表你的閱讀理解具有很好的全局觀。
統整段落資訊與選項分析
這篇文章的第一、二段首先澄清了「太平洋垃圾帶」並不如大眾想像中是一座明顯可見的垃圾島，而是由肉眼難以察覺的微小塑膠組成。第三段解釋了為何塑膠會成為海洋廢棄物的大宗，最後一段則點出清理這些塑膠垃圾面臨著生態、時間與經費上的巨大挑戰。綜合這些內容，文章的主線就是在探討一個難以解決的污染問題，因此選項 (B) "A pollution that is difficult to tackle." 完美契合了全文的論述。相較之下，選項 (A) 提及的生物多樣性並非文章重點，而 (C) 塑膠分解與 (D) 衛星觀測都只是文章中的局部細節，不能作為整篇文章的主旨。
