記錄的意義
經常會有人問我，垃圾撿起來裝袋就好了，為什麼還要算？那麼麻煩做什麼？我總是說這樣才知道什麼垃圾有多少，才可以突顯出問題的嚴重。每個月一次的來到沙灘上，讓我們發現不同的季節會出現不同的垃圾，有時候會出現大量的塑膠袋，塑膠袋全都是風化後的碎片，是從海上飄過來的，有時候會出現大量的蚵架，之後就會出現大量的保麗龍，如果是大雨過後，飲料相關如塑膠杯、保麗龍杯就會特別多，另外如飲料玻璃瓶，則全年無休都很多，而且都是提神飲料；2008年夏天，接連的幾個颱風，沙灘上出現大量的海飄垃圾，有長滿貝類的大酒瓶，有很多如頭皮削般的塑膠袋碎片，有數不盡的塑膠微粒，都是在海上漂流很久粉碎後的塑膠製品。

Why Should We Collect the Data?
Lots of people are wondering why bothers to count every piece of litter picked up from the beach.  If we don’t do so, we are unable to discover how serious the problem is.  The cleanup is conducted once a month regularly and we discover that different kinds of liter would be washed on shore during different seasons.  Sometimes there are great numbers of plastic bags from the sea, and they are broken into tiny pieces.  Sometimes many oyster racks are washed on shore, then the Styrofoam.  Particularly, disposable plastic and Styrofoam beverage cups are many in numbers after torrential rain.  What’s more, glass beverage bottles, especially energy drinks, are many in numbers year-round.  After several typhoons hit Taiwan in the summer of 2008, great amount of liter was washed on shore including countless tiny plastic particles, which were drifting in the ocean for long.

我們從每次撿的垃圾種類、數量做名次排列，從中看到了一些值得大家注意的現象：

1、河流會將陸地上大量的垃圾帶到海洋，尤其大雨過後特別明顯。

2、河口的垃圾很多樣，以生活用品居多，喝完即丟的飲料容器是垃圾的最大宗，包括保力龍杯，塑膠飲料杯，塑膠飲料罐及飲料玻璃瓶。飲料玻璃瓶數量一直都很多，且都是提神飲料如保力達B及蠻牛等，環保署的相關回收機制或限制使用應該要強制執行。保麗龍一直是二仁溪這裡數量最多的垃圾，大都是漁業用的，尤其是蚵架，當蚵收成蚵架棄養後，海邊的保麗龍就急速增加，臺南市淺海牡蠣養殖管理自治條例自2008年公告實施，我們應支持、督促政府強力執行，若執行良好將可大量減少保麗龍的污染問題。保力龍是一般應回收的廢棄物，但實際上回收機制做的不好，保力龍飲料杯更是氾濫。海岸線即將被保力龍淹沒，海洋垃圾將會是海洋台灣走向國際的第一步。前半年撿到的醫療廢棄物數量很多，藥用玻璃瓶、注射針筒非常多，現在已經較少，但一直都有。

3、另外我們發現一個非常嚴重的問題，就是我們在撿垃圾的沙灘不見了！幾百公尺及一兩公尺高的沙丘全沒了～是全球暖化造成氣候異常？或是安平港及興達港的凸堤效應？我們不知道，但海流變了，地貌變了，沙灘消失了，才短短兩年，志工們就感慨的說變化也太大了吧！

We observe some phenomena that needs everyone’s attention from the data we collect,

1.          Land based litter flows in great amount from river to the sea, particularly after torrential rain.

2.          Litter at the estuary is various, and mostly it is from the households.  Number one litter is disposable beverage cups, including Styrofoam cups, plastic cups, plastic beverage bottles, and glass beverage bottles.  Glass beverage bottles are always many in numbers, particularly energy drinks.  Environmental Protection Administration should come up with better recycle policy and limit the use of them.  Styrofoam is always the number one litter at the Erhjen Creek, mostly used for fishery purpose.  After the oysters grow and reaped in the sea, the Styrofoam debris increases rapidly.  Autonomy Regulations of Oyster Farming in Tainan was implemented in 2008, and we should urge the government to carry out the regulations thoroughly to mitigate the Styrofoam pollution.  Styrofoam isn’t recycled properly, particularly the Styrofoam beverage cups.  The Tainan coast is largely covered by the pollution.  Medical hygiene was also in great amount before, such as medical glass bottles and syringes.  Recently the numbers of them are less, but they are still found regularly on the beach.

3.          Another serious problem we found is that the beach we used to clean up is disappearing.  This beach, hundreds meters in length and two meters in height, disappeared in only two years.  We wonder what the cause is, climate change or the newly harbor construction?  We do not know yet.  However, we do know that the sea current has changed, the landscape has changed, and our beach has disappeared.
