This perhaps wouldn't be too much of a problem if the plastic had no ill effects. The larger items, however, are consumed by seabirds and other animals which mistake them for prey. Many seabirds and their chicks have been found dead, their stomachs filled with medium sized plastic items such as bottle tops, lighters and balloons. A turtle found dead in Hawaii had over a thousand pieces of plastic in its stomach and intestines. It is estimated that over a million sea-birds and one hundred thousand marine mammals and sea turtles are killed each year by ingestion of plastics or entanglement in plastics.
Environmental organizations such as Greenpeace are trying to do something about the world's largest landfill.
We can do something, too. We can contribute to such organizations. They always need our financial help. We can also think before we toss stuff into the trash. Certainly none of us would toss our empty water bottles onto a beach but how about instead of the trash we recycle? Or even more radical, how about we stop buying those individual water bottles. How about we buy a good, reusable water bottle and fill it from if not the faucet our filtered water or our five gallon home delivered water bottles?
At the very least we can be aware that most of the things we throw away are never actually gone.
