Are Your Clothes Causing Pollution?
Very small pieces of plastic, called microfibers, are polluting rivers and oceans.Clothes worn for outdoor activities and exercise are often made of artificial material, which is useful in keeping warm. But they contain very small plastic fibers, which may also be harming the environment when you wash them. When people wash these clothes, very small pieces go down the drain (下水道) with the wash water.
Pollution caused by plastic is not new, but recent studies have shown the effect of microfibers in the environment.
Studies show very small microfibers are ending up in our waters, which may come from waste water treatment factories. A 2015 study found them in fish from California.
Microfibers, effect on food supplies.
Beyond the waterways, the researchers say microfibers may end up in soil and agricultural lands.This means there is much to be learned about microfibers and the environment. Some studies have shown that microfibers end up inside sea animals, like oysters.Researchers say that the fibers tend not to move into the tissue of the fish, but it needs more study.
Steps to save or keep microfibers from the environment.
Until more information becomes known, there are steps to take to reduce the amount of microfibers in the environment. People should use less of the artificial materials. If we already have those in our lives and we're using them, an important step would be washing them less.A bag is being designed in which to wash these clothes. It traps the microfibers in the bag and it may be available for purchase soon.
A. New technology may also help.
B. Studies on microfibers in the environment.
C. They can also move around the atmosphere.
D. Studies on how much of the microfibers is released.
E. The source of these microfibers may surprise you: your clothes.
F. Washing machines keep microfibers from escaping with wash water.
G So if these microfibers have been found in fish and seafood, are they safe to eat?
Lindsay Renwick, the mayor of Deniliquin, a country town in New South Wales, misses the constant whir(嗡嗡声)of the rice mill whose giant fans dried the rice. The Deniliquin mill, the largest rice mill in the Southern Hemisphere (南半球), once processed enough grain to meet the needs of 20 million people globally. But six years of drought have had a destructive effect, reducing Australia's rice crop by 98 percent and leading to the mothballing of the mill last December.
Drought affects every agriculture industry based in Australia, not just rice – from sheep farming, the country's other backbone, to the cultivation of grapes for wine, the fastest-growing crop there, with that expansion often coming at the expense of rice. The drought's effect on rice has produced the greatest impact on the rest of the world, so far. It is one factor contributing to skyrocketing prices, and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production.
Researchers are looking for solutions to global rice shortages – for example, rice that blooms earlier in the day, when it is cooler, to fight against global warming. Rice plants that happen to bloom on hot days are less likely to produce grains of rice, a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb. 'there will be problems very soon unless we have new varieties of rice in place,” said Reiner Wassmann, climate change director at the International Rice Research Institute (IRRI). The recent reports on climate change carried a warning that could make the news even worse: that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable.
Yet the effects of climate change are not uniformly bad for rice. Rising concentrations (浓度) of carbon dioxide, the main greenhouse gas, can actually help rice – although the effect reduces or disappears if the plants face unnecessary heat, inadequate water, severe pollution or other stresses. Still, the flexibility of farmers here has persuaded some climate experts that, particularly in developed countries, the effects of climate change may be relieved, if not completely avoided. “I'm not as negative as most people,” said Will Steffen, director of the Fenner School of Environment and Society at Australian National University. “Farmers are learning how to do things differently.”
Meanwhile, changes like the use of water to grow wine grapes instead of rice carry their own costs, as the developing world is discovering. “Rice is an essential food,” said Graeme Haley, the general manager of the town of Deniliquin. “Wine is not.”
