![]() Erasers come in a wide range of shapes, from the traditional rectangular block to more specialized shapes such as pens and pencils. Shape and sizeĪnother important factor to consider when choosing a pencil eraser is the shape and size. Synthetic polymer erasers, on the other hand, are firmer and more abrasive, making them better for erasing larger areas or tougher pencil marks. Rubber erasers are generally softer and more pliable, making them better for erasing fine details and small mistakes. The most common materials used for pencil erasers are rubber and synthetic polymer. One of the first things to consider when choosing a pencil eraser is the material it is made from. But with so many different types of erasers available, how do you choose the right one for your needs? In this article, we will explore some of the key factors to consider when selecting pencil erasers. ![]() Without a good eraser, even the most skilled artist or writer can make mistakes that are difficult or impossible to fix. When it comes to pencils, erasers are just as important as the lead itself. Microfibers can float through the air and eventually settle in the ocean or be carried by rivers and wastewater into the ocean.Learn More About Purchasing the Pencil Erasers Introduction When we wash clothing, microfibers break apart from the fabric and can find their way into the ocean. These synthetic materials are used to make clothing, furniture, fishing nets, and other products. Most of these microplastics were microfibers, from materials such as polyester or nylon. This is roughly the same amount found in Boston Harbor! One National Park Service study counted just over 40 pieces of microplastics per pound of sand. While the Bering Land Bridge coastline may not be littered with brightly colored microplastics, that doesn’t mean they’re not there. "Every plastic that has ever been produced is still here, it's just breaking down into smaller and smaller particles, and so it's really important to get the larger pieces of plastic off of the beach before they become microplastics out in the ocean."Īrctic sea ice in remote locations can contain high concentrations of microplastics, surpassing some highly contaminated surface waters in other parts of the world. There is no part of the ocean left untouched by marine debris. However, more research is needed to understand how wildlife and people might be affected. Wildlife may ingest or be exposed to these contaminants, which is of particular concern for Alaskan communities that depend on harvesting marine mammals and resources. Microplastics can absorb harmful pollutants or leach out toxic chemicals. These animals are ingesting a side of microplastics along with their plankton soup. Plankton are tiny animals (zooplankton) and plants (phytoplankton) that are important food for the tiniest of fishes to the largest of whales. In the ocean, microplastics can mix in with pockets of nutrient-rich water, which is full of seasonally abundant plankton. ![]() Some are not even visible to the human eye! Microplastics come in many forms, including beads, fragments, pellets, and fibers. ![]() Plastic pieces that are less than 5 mm, or the size of a pencil eraser, are called microplastics. Plastic never disappears, it just breaks up into smaller and smaller pieces. Can you find the marine debris in your mouthful? Imagine you are a juvenile saffron cod swimming through the Bering Sea. It can be hard for animals to tell what’s plankton and what’s microplastic when swimming through the ocean.
