When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl (水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres (英亩) of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat.

In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory (迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. “Ding” Darling, a political cartoonist from Des Moines, Iowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.

About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System — a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.

Parents usually teach their children how to cross the street safely by looking both ways for cars. But do they also teach them to put away their cell phones?

Texting while crossing the street will soon be forbidden in the city of Honolulu, Hawaii. Beginning on October 24, you could be fined from $15 to $99 if you step into a Honolulu street while looking at your phone. Honolulu is the first major U.S. city to forbid what is called "distracted (分心的) walking." It recently passed a law in a seven to two vote. The law says: "No pedestrian (行人) shall cross a street or highway while viewing a mobile electronic device (设备)." In other words, do not look at a screen when you cross the street or you could be fined.

The law’s creators hope it will lower the number of people hit and killed by cars in the city. Mayor Kirk Caldwell told Reuters news agency, "We hold the unfortunate distinction (区分) of being a major city with more pedestrians being hit in crosswalks, particularly our seniors (老年人), than almost any other city in the country."

The law includes all electronic devices with screens: cell phones, tablets, gaming devices, digital cameras and laptop computers. The law does permit an exception. Pedestrians may use such devices in the street to call emergency services and rescue workers, such as firefighters and police officers.

Pedestrian deaths have been increasing as the use of cell phones rises. The Governors Highway Safety Association says pedestrian deaths in the United States increased 25 percent between 2010 and 2015. That trend (趋势) continued in 2016 with the number of pedestrian deaths rising to almost 6000, 11% higher than in 2015.

If you still want to text while walking, you could avoid being fined in Honolulu (and be safer, in general) by using a voice-controlled digital assistant such as Siri or Google Assistant. Or you could just wait until you are again, safely, off the street.

Seattle on Sunday became the first major US city to ban drinking straws(吸管), an environmentally friendly move that leaders hope will spark a nationwide conversation about small, everyday changes that people can make to protect the planet.

A decade ago, the city adopted a law requiring that all one-time-use food-service items be compostable(可分解的) or recyclable. But straws were exempted from that law because there were not many good alternatives. So the straws stayed, along with the environmental problems they cause.

Most plastic straws aren’t heavy enough to make it through industrial recycling sorters, and can ruin an otherwise good load of recycling. Or they end up getting blown out of trash cans and car windows and eventually wind up in the oceans, where they can hurt wildlife.

Strawless Ocean estimates that 71 percent of seabirds and 30 percent of turtles have some kind of plastic in their stomachs. The organization says plastic can increase the death rate of marine life by 50 percent.

Now customers at grocery stores, restaurants, food trucks, even institutional cafeterias have to find another way to get liquid into their mouths. Compostable paper straws are allowed under the ban. People who have a medical need to use a straw are not included. 

Failure to obey may result in a US$250 fine, although city leaders said that the purpose of the law is more about raising awareness. In September, 150 businesses participated in Strawless in Seattle, an attempt to reduce the use of plastic straws. In that month alone, Strawless Ocean estimates, 2.3 million plastic straws were removed from the city.

“When you get your iced drink, you’re going to get a straw. When you get your wine, you’re probably going to get a straw,” said Dune Ives, executive director of the Lonely Whale Foundation, which led the campaign. “Imagine a world where we could stop consuming 500 million straws a day, just in America!” the campaign says. “Imagine a world that is less dependent on plastic. That’s change we can start today!”
