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.

6 . In the endless sky, the unaided human eye should be able to perceive several thousand stars on a clear, dark night. Unfortunately, growing light pollution has impeded people from the nightly view.
New citizen-science-based research throws alarming light on the problem of “sky glow”-the diffuse illumination (漫射照明) of the night sky that is a form of light pollution. The data came from crowd-sourced observations collected from around the world as part of Globe at Night, a program developed by astronomer Connie Walker.
Light pollution has harmful effects on the practice of astronomy but also on human health and wildlife, since it disturbs the cycle from sunlight to starlight that biological systems have evolved alongside. Furthermore, the loss of visible stars is a great loss of human cultural heritage. Until relatively recently, humans throughout history had an impressive view of the starry night sky, and the effect of this nighty spectacle (壮观) is evident in ancient cultures.
Globe at Night has been gathering data on star visibility since 2006. Anyone can submit observations through the Globe at Night web application. Participants record which one best matches what they can see in the sky without any telescopes or other instruments.
Researchers find that the loss of visible stars indicates an increase in sky brightness of 9.6% per year while roughly 2% is measured by satellites. Existing satellites are not well suited to measuring sky glow as it appears to humans, because they can not detect wavelengths shorter than 500 nanometers (纳米). White LEDs, with shorter wavelengths under 500 nanometers, now are increasingly commonly used in outdoor lighting. But human eyes are more sensitive to these shorter wavelengths at nighttime. Space-based instruments do not measure light from windows, either. But these sources are significant contributors to sky glow us seen from the ground.
“The increase in sky glow over the past decade underlines the importance of redoubling our efforts and developing new strategies to protect dark skies,” said Walker. “The Globe at Night dataset is necessary in our ongoing evaluation of changes in sky glow, and we encourage whoever can to get involved to help protect the starry night sky.”

Just as noise pollution negatively impacts human health, it also affects wildlife. It can affect animal communication, their abilities to find food and impact where they live. A recent study published in Biology Letters found that human-created noise is affecting a wide range of animals. Noise pollution is caused by cars, trucks, airplanes, ships, factories, industrial activities and sounds from cities, among others. Researchers found that wildlife in many different land and water ecosystems showed significant responses to human-created noise.
For example, bats use ultrasonic sound waves to get around and to find food. However, noise pollution affects this and causes them to spend more time and energy locating their food source. Shipping lanes in the UK can be deafening to harbor seals, and noises from ships are seriously impacting killer whales ability to find food and avoid potential dangers, according to episode 2 of CBC s Killers: J pod on the brink (边缘). And it’s no secret that many human-created conditions, like noise, are changing the behavior of birds. You may be surprised to learn that plants are also impacted, since pollinators (传粉昆虫) often relocate to quieter areas.
Not unlike the impact of light pollution on insects, noise pollution is causing change. It can change the types of species living in many different ecosystems, which in turn impacts the functions of these areas, according to The Guardian.
The good news is that if noise is reduced or simply turned off, it more or less removes the issue. The impact does not remain in the same way as other forms of pollution, like plastic or chemicals. And efforts are already underway in Canada.
BC Ferries is working to lessen the effects of underwater noise, especially along ferry routes that pass through critical habitats. WCS (Wildlife Conservation Society) Canada is encouraging the federal government to increase protective measures in the Arctic. They’re also working with international colleagues to address the increase of noise in the region as a result of new shipping routes.
While these initiatives demonstrate progress, tightening rules and regulations around noise pollution is an important measure for conserving wildlife in Canada.

8 . Scientists visiting Henderson Island in the South Pacific recently made an alarming discovery. Despite being one of the most remote and previously untouched places on Earth, the island was covered in plastic waste. Shockingly, they estimated there were 38 million pieces of plastic, weighing nearly 18 tons, with thousands of new pieces washing up daily.
Plastic takes hundreds of years to decompose, meaning that actually all the plastic ever produced still exists in some form. Unfortunately, approximately 95% of plastics are not recycled, and substantial amounts end up in the ocean. Currents collect this waste in large circular systems called “gyres (环流)”. The problem gets worse as plastic breaks down into very small pieces, or “micro plastic”. This is eaten by fish and leads to massive species loss. Humans also eat these fish, and micro plastic has even been found in tap water around the world. The plastic on Henderson Island accounts for just 2 seconds’ worth of global annual plastic production.
However, there are some young minds working to clean up and protect the sea for future generations. Young Boyan Slat decided to dedicate his life to solving this problem. Previously the problem was considered too big to solve; collecting the plastic with boats and nets would be expensive, would harm sea life, and would take thousands of years! But, Boyan thought, why move through the sea when the sea can move through you? To work with the currents and gyres would help collect the waste. So he started The Ocean Cleanup project, which places very long floating barriers in the Pacific. Currents then concentrate the waste naturally so it can be collected and recycled.
Boyan reflects on the broader issue, stating, “Many problems today are side effects of things people didn’t think about in the past. Sea plastic is a symbol of the negative effects of our lifestyle and technology. Our aim should be to create a new lifestyle for this century. Protecting the sea from plastic is a good place to start.”

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)

New research links outdoor air pollution — even at levels considered safe — to an increased risk of diabetes (糖尿病) globally, according to a study from the VA St. Louis Health Care System. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.
Diabetes is one of the fastest growing diseases, affecting more than 500 million people worldwide. The main drivers of diabetes include eating an unhealthy diet, having a sedentary lifestyle and obesity, but the new research indicates the extent to which outdoor air pollution plays a role.
“Our research shows a significant link between air pollution and diabetes globally,” said Ziyad Al-Aly, MD, the study’s senior author and an assistant professor of medicine at the University of Washington. “We found an increased risk, even at low levels of air pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO). This is important because many industry lobbying (游说) groups argue that current levels are too stringent and should be relaxed. Evidence shows that current levels are still not sufficiently safe and need to be tightened.”
While growing evidence has suggested a link between air pollution and diabetes, researchers have not attempted to quantify that burden until now. “Over the past two decades, there have been bits of research about diabetes and pollution,” said Al-Aly. “We wanted to thread together the pieces for a broader, more solid understanding.”
The researchers also found that the overall risk of pollution-related diabetes tilted (倾斜) more toward lower-income countries such as India that lack the resources for environmental mitigation systems and clean-air policies. For instance, poverty-stricken countries facing a higher diabetes-pollution risk include Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experience a lower risk. The US experiences a medium risk of pollution-related diabetes.
