Imagine you are out fishing on the high seas - the wind and water are clean and comfortable and you begin bringing up your first catch of the day. That's when everything goes wrong. Your fishing nets are tangled up (缠成一团) in older, abandoned fishing tool, and you're unable to untangle them. Your equipment    1    (ruin), and all of the fish you have worked so hard to catch are trapped. They will die    2    you are unable to draw or free them. Ghost fishing has claimed yet another victim.

Ghost fishing is what abandoned fishing tool does. It still catches fish, but no one benefits. Trapped fish die and attract scavengers (清道夫)    3     also get caught, creating a vicious cycle. In fact, lost fishing tool, or "ghost tool," is among    4    (great) killers in the oceans. This tool further reduces the already declining number of fish.

Environmental agencies estimate that 10 percent of all seawater litter is lost or deserted fishing tool    5    (equal) 640,000 tons every year. Fortunately, these agencies are asking why this is happening and what    6     be done to stop it.

It's not the intention of the majority of fishermen to lose their tool. In most circumstances bad weather is to blame. But in other cases fishermen throw their tool in the ocean on purpose, risking expensive fines. But to them, it's worth the risk    7    (free) up space onboard, cut fuel costs or avoid paying handling fees.    8     equipment loss is accidental or not, a strategy involving tool identification seems to be a practical solution.

By marking tool with electronic tags and utilizing GPS technology, owners are more likely to recover lost tool and less likely to abandon it. Currently, ownership regulations are reportedly very weak. Leading the effort for tagging fishing tool and creating accountability is the GGTI (Global Ghost Tool Initiative).    9     (launch) in 2015, the GGTI is the first organization of its kind. It's brought together an organization of governments, fishing-industry executives, seafood companies and non-profits. Their efforts to get back and recycle the tool    10    (improve) marine environment, protecting fish and fishermen's way of life.

Ghost fishing poses a serious threat to the fishing industry worldwide, and a global effort is needed to solve it.

2 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.

Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.

While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.

In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.

Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.

These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.
