1 . The Yurok people have lived along the Klamath River, which flows from the Cascades in Oregon southwest through Northern California, for thousands of years, protecting the region and river from which they — and others — draw sustenance (生计).
But as development and pollution continue to reduce the number of fish in the river and the quantity and quality of its waters, the Yurok Tribe is legalizing (合法化) the tribe’s longstanding care by granting the Rights of Personhood to the Klamath, the first river in North America to have such rights declared.

Microplastics in Water — a Wake-up Call for All of Us
Today researchers announced that they have found tiny pieces of plastic in water samples from around the world. These pieces are called microplastics and are so small that they are invisible to the naked eye and are very difficult to remove from the water. When in the water, they are swallowed by fish and other animals and then enter the food chain.
Even more concerning is the fact that the plastic has also been found in drinking water across the world. This means that we are drinking plastic every day. Scientists do not know what level of harm this will cause us in the future.
Microplastics come from a number of different sources, in particular from washing and drying synthetic (non-natural) clothing and from cosmetics and cleaning products, such as toothpaste and face washes. Microplastics are even found in the air outside and at our homes.
Almost every country across the world agrees that we cannot continue using so much plastic in our lives. We need to find a solution to remove microplastics from our oceans. We also need to introduce new taxes and other means to encourage companies to choose environment-friendly ingredients and recyclable packaging for their products.
We need to take personal responsibility, too. We all have the freedom to choose how we spend our money and what kids of business and products we support. Let’s work together to protect our environment, both now and for the future.
Remember: Reduce — Reuse — Recycle. (244 words)

My husband and I always wanted to go to the Caribbean but didn’t know much about the islands or how we were going to afford it. By chance, a friend of ours in Australia mentioned “pet sitting” and that it is something you can do all over the world.
We quickly created an account on a pet sitting website and began searching for options. There were only a couple of sits available in that part of the world, but we tried our luck, sent a request, and to our surprise, landed a three-month job in Grenada, so our year was going to be taken up with Caribbean pet sits.
Inspired by a Canadian couple, we decided to start our own travel blog. We began by writing about The British Virgin Islands, highlighting the beautiful beaches. However, for every photo album of a beautiful beach, there were 10 photos of trash (垃圾). It was hard to ignore the plastic pollution issue, especially on such primitive and remote beaches. So, we began to share photos of the trash we saw and how much we could pick upon our daily dog walks.
The more we looked into plastic pollution, the more we realized the severity of the global plastic pollution. From that point, we used our platform to create awareness and highlight ways to say no to plastic and travel plastic-free. We changed our daily routines, our way of living, and even our diets to accommodate more organic foods and little to no plastic packaging.
It’s been over three years now and we continue to do what we can. This journey has led us to some amazing places, working with great brands and even organizing a country-wide beach clean-up campaign in Grenada.
Our aim now is to keep on going. We love connecting with like-minded people. It’s been amazing few years that was sparked by a conversation about pet sitting. Who would have guessed?

8 . Three hundred million children live in areas with extreme air pollution, new research by the United Nations International Children’s Emergency Fund(UNICEF)reveals. The air they breathe is more than six times as polluted as what is considered safe. The new study was the first to make a global estimate of pollution exposure. It shows that almost 90 percent of the world’s children—two billion—live in places where outdoor air pollution levels are dangerously high.
UNICEF warned that these levels of global air pollution have contributed to 600, 000 child deaths a year. Children are far more likely to be harmed by air pollution than adults are, UNICEF said. So, UNICEF urged nations to cut fossil fuel burning rapidly. Fossil fuels, such as coal and gas, are the main source of air pollution. “The danger caused by air pollution is enormous,” said Anthony Lake, UNICEF’s executive director. “No society can afford to ignore air pollution. We protect our children when we protect the quality of our air, both of which are central to our future.”
Air pollution is the world’s single biggest environmental health risk, and it is getting worse, with levels of poisonous air rising 8% in the last five years. More than three million people a year die as a result of outdoor air pollution—six every minute on average. Such deaths are set to double by 2050 as fast-growing cities expand. Indoor air pollution, mainly from wood stoves, causes another three million deaths a year.
Meanwhile, children are especially at risk, the UNICEF report says, because they breathe more rapidly than adults and their lungs take in more pollutant particles. The tiny particles can also cross the blood-brain barrier, which children are more susceptible to. Once they do, they can permanently harm brain development. Even the unborn are affected, as the particles taken in by a pregnant woman can injure a child in the womb.
Children in poor countries are doubly at risk, scientist Jos said. Their bodies are often already weakened by not getting enough to eat, and available health care is often inadequate. Of the 300 million children exposed to levels of pollution six times above what is considered safe, 220 million live in South Asia. India in particular hosts many of the world’s most polluted cities. Moreover, figures reveal a striking disparity in five-year cancer survival rates for children in air polluted areas compared with those from developed countries.
UNICEF urged all countries to cut air pollution by reducing fossil fuel burning in power plants and vehicles. It also recommended that schools and playgrounds not be located near sources of pollution, such as busy roads and factories. In addition, it called for the use of less-polluting cooking stoves.

9 . If humans were truly at home under the light of the moon and stars, we would go in darkness happily, the midnight world as visible to us as it is to the vast number of nocturnal (夜间活动的) species on this planet. Instead, we are diurnal creatures, with eyes adapted to living in the sun’s light. This is a basic evolutionary fact, even though most of us don’t think of ourselves as diurnal beings. Yet it’s the only way to explain what we’ve done to the night: We’ve engineered it to receive us by filling it with light.
The benefits of this kind of engineering come with consequences — called light pollution — whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky. Ill-designed lighting washes out the darkness of night and completely changes the light levels — and light rhythms — to which many forms of life, including, ourselves, have adapted. Wherever human light spills into the natural world, some aspect or life is affected.
In most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze (霾) that mirrors our fear of the dark. We’ve grown so used to this orange haze that the original glory of an unlit night — dark enough for the planet Venus to throw shadow on Earth — is wholly beyond our experience, beyond memory almost.
We’ve lit up the night as if it were an unoccupied country, when nothing could be further from the truth. Among mammals alone, the number of nocturnal species is astonishing. Light is a powerful biological force, and on many species it acts as a magnet (磁铁). The effect is so powerful that scientists speak of songbirds and seabirds being “captured” by searchlights on land or by the light from gas flares on marine oil platforms. Migrating at night, birds tend to collide with brightly lit tall buildings.
Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times brighter than normal, throwing nearly every aspect of their behavior out of joint, including their nighttime breeding choruses. Humans are less trapped by light pollution than the frogs. Like most other creatures, we do need darkness. Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.
Living in a glare of our own making, we have cut ourselves off from our evolutionary and cultural heritage — the light of the stars and the rhythms of day and night. In a very real sense light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way — the edge of our galaxy — arching overhead.
