On the other hand,
A couple of years ago, I had the pleasure of teaching a young couple to dive (潜水) in Thailand on one of my favorite reefs (礁). The weather conditions were perfect, with mild currents and excellent sight of the beautiful ocean and the bright, vivid corals. Even with their masks on, I could see the smiles on my students’ faces.
The dive couldn’t have gone better. However, things changed as we made our way back to the boat. As we swam back along the reef, I noticed the current (水流) changing. As it did, huge quantities of trash and plastic began to flood the area. I saw small reef fish swimming amongst the straws, plastic bags and other bits of rubbish. I noticed that some of the fish were pecking away (啄) at the plastic. By the time we got back onboard the boat, there were bits of plastic floating all around us. It looked more like a trash site than the ocean.
When I got home, the first thing I did was to go online and research plastic pollution in the ocean. I was surprised to find out that over the past decade, divers and beach lovers have seen a lot of changes in the oceans. Even very remote locations were suddenly filled with plastic and other chemicals. Plastics were entering our oceans at an alarming rate—up to 12 million tons each year. This huge amount of plastic was wreaking havoc (破坏) not only on the environment, but also on the marine animals that lived in the ocean, such as sea turtles and sea birds. Some of them were sadly mistaking the pieces of plastic for food. Pollution has brought our oceans to the point of disaster, and unless we make a great change, then our oceans and all of its living things, will be at risk.
Since that unforgettable plastic-polluted dive, I have become an ocean supporter and spend my days trying to get the message out there about just how harmful ocean pollution is, not only to marine life, but also to mankind.

Then the idea came to me: I could appeal to my fellow divers to take action.

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.

4 . Recycling is a great way of doing your bit for the environment and helping to protect the earth’s precious resources. However, a new study has revealed that our desire to be sustainable maybe doing more harm than good. According to waste company Biffa, this is because of “wish-cycling” — assuming that items such as disposable coffee cup sand pizza boxes will be recycled if put in the recycling bin. In fact, pollution from those items or other non-recyclables can result in recyclable items that have been put in the correct bin going to landfill. David Heaton, a business director at Biffa, said: “Pollution happens when items are disposed of in the wrong bins or haven’t been cleaned before being recycled.”
Experts at Biffa analyzed the amounts of non-target and non-recyclable materials that entered UK material recycling facilities between 2016 and 2020. It was found that, in 2016, the average pollution rate of recycling waste was 13.4 percent, rising over four years to 17 percent by the end of 2020. This shows that, even as people are becoming more eco-conscious, wish-cycling is increasing both in households and businesses.
The Biffa experts say that one of the best ways to prevent pollution of recycling is to clean recyclable waste before putting it in the bin. They suggest cutting off the top of old pizza boxes and only recycling that part to avoid pollution from the grease (油脂). Check the on-packaging recycling label to check it can actually be recycled When it comes to plastics, Biffa recommends checking the resin code, the number in the plastic triangle, to know whether it should go in the recycling bin. In general, resin codes 1, 2, 4 and 5 are recyclable, while 3, 6 and 7 are not. Larger items, like electronics, furniture and batteries, can also be recycled but often can not go in household recycling bins as they need specialist separating. These will need to be taken to recycling centers or sustainable waste management companies.
“It’s vital as a nation that we get better at effective ‘pre-cycling’— sorting waste correctly before collection to reduce pollution rates,” added Mr. Heaton.
