2 . Working Together to Save the Sea Turtles

Florida has some of the best beaches in the world. Thousands of people visit the state to enjoy the sand. But these beaches are also home to five species of sea turtles. A major problem is facing these interesting creatures.     1     So how do Floridians protect these special animals?

Some volunteers and researchers in Florida take direct action to help the turtles. They look closely at the sand to find the fin (鳍) marks the mother sea turtles left there.     2     When they’ve figured out where the eggs were laid, they mark the area off so that no one disturbs the eggs. They also collect information about the nests and tracks to help people studying sea turtles.

These are not the only Floridians taking action to help protect these creatures. Florida’s government has passed laws to save the turtles. One of these laws is “Florida’s Marine Turtle Protection Act”. This law prohibits anyone from disturbing or destroying marine turtles, nests, or eggs.    3    

Another way Floridians work together to save these creatures is through organizations like the Sea Turtle Conservancy. The Sea Turtle Conservancy helps people take steps that will help reduce the threats that put sea turtles in danger. For instance, bright lights on buildings near the beach can negatively impact sea turtles. Baby sea turtles usually hatch on the sandy beach and head to the ocean. When there are bright lights coming from the other side of the shore far from the ocean, the baby turtles get confused.     4     To help save these turtles, The Sea Turtle Conservancy works with property owners to make lighting in their buildings sea turtle-friendly. They also encourage Florida residents to turn off their lights at night if they live close to a beach.

    5     Sometimes, turtles mistake plastic bags for jellyfish. They eat this trash and die. Florida residents can volunteer for beach clean-ups and make sure to pick up their own litter. They can also vote for state leaders who want to protect the sea turtles’ habitats. Every individual in the community has the power to make a difference!

E-waste is a serious problem that isn’t going to get better on its own. Here are some do-it-yourself tips on how to manage e-waste.

Maybe the biggest cause of our e-waste problem is the fact that we buy things that we just don’t need. Next time you feel like you need a device or electronic item, stop yourself and ask if it is truly necessary. This is maybe also the easiest way we can manage e-waste. Organize your electronics. If you don’t keep your connectors, DVDs, wires and gadgets organized, you won’t be aware of what you have. When we buy duplicate electronics because we think we need them, we are contributing to our growing e-waste problem. “How to manage e-waste” becomes less of an issue when we keep our own houses in order.

If you do not need a piece of equipment and it is in good enough condition to be reused, donate it as soon as you can so that somebody else can use it. Donations are good for us because they are a useful way to get tax deductions, and a lot of times that tax deduction will be close to the value of the item had you tried to sell it. Take your electronics back to the store. Some stores offer trade-in programs, where you can drop off your old equipment in return for gift cards.

There are also places to sell electronics that might be valuable to somebody else. Just be sure to sell them right away, because they lose value very rapidly in our changing market.

If you are frequently receiving memory sticks and little gadgets, collect them into a good-e-bag. Whenever you no longer need a USB stick or a small electronic device, toss it into the bag. You might be surprised at how quickly it fills up. So be sure you are utilizing your materials and products thoughtfully. With these tips you can use DIY solutions to learn how to manage e-waste. Your house will be cleaner, you will save money and you’ll be doing a good thing.

5 . Alarming reports that the Antarctic ice sheet is becoming smaller misrepresent the facts. The ice sheet holds about 26.5 million gigatons(十亿吨)of water. If it were to melt(融化)completely, sea levels would rise 190 feet. Such a change is an issue for the far future, if it comes at all.

Much more modest ice loss is normal in Antarctica. Each year, some 2,200 gigatons of the ice is discharged(消融), while snowfall adds almost the same amount. The difference between the discharge and addition each year is the annual loss. That figure has been increasing, from 40 gigatons a year in the 1980s to 250 gigatons a year in the 2010s. But the increase is just a slight change in a complex process. If it continued at that rate, the sea level would be raised by 3 inches over 100 years.

Many fear that a warming globe could increase discharge and cause more rapid sea-level rise. Two recent studies focus on this issue. Researchers in the study of Thwaites Glacier(冰川)—an unusually broad and fast Antarctic glacier—infer that in the past it became smaller for half a year at more than twice the fastest rate ever observed. The cause of this specific event remains unknown, partly because the time of the rapid melting hasn’t yet been determined. But the media goes with this angle: “A ‘doomsday(末日)glacier’, the size of Florida, is breaking faster than thought.”

A second study tested the idea that the melted freshwater could be carried by currents to speed up the discharge of nearby glaciers. Researchers constructed a special model to prove their idea. If ocean currents can connect the discharges of distant glaciers, that would add to the complexity in the Antarctic ice sheet. To emphasize their idea, researchers used human influences almost three times larger. Even though that fact is stated in the paper, reporters rarely catch such nuance, and the media goes with headlines such as “a massive tsunami would drown New York City, killing millions.” A more accurate headline would read: “Ocean currents connecting Antarctic glaciers might quicken their melting.”

These two studies were conducted with clever methods to infer past conditions and advanced computer modeling to show possible situations. These papers describe the science with appropriate precision and caution, but it is a shame that the media misrepresents the research to raise alarm. That denies the public the right to make informed decisions about “climate action,” as well as the opportunity to be amazed at the science itself.

6 . The bald eagle was once a dying species in the United States. This is because the bird wasn’t always held with respect. At the National Book Festival, author Jack E. Davis detailed the bald eagle’s “great conservation success story”.

The bald eagle has faced extinction twice. The first occurred in the late 19th century. “It was then that a bald eagle seen was one to be shot,” he said. He explained that the bird had been regarded as a dangerous animal, and considered a threat. But such threat tended to be overstated. Throughout the early 20th century, thousands of bald eagles were shot down. Things began to change for the bird in 1940, when the government passed its legal protection — the Bald Eagle Protection Act.

However, only five years later, the bird faced its second near extinction when DDT, an environmentally harmful insecticide (杀虫剂), was introduced at the end of World War Ⅱ. In 1963, the bald eagle hit its lowest number — totaling less than 500 nesting pairs across the U.S. “At that time, only about one-third of the nation’s water was safe for swimming and fishing,” Davis said. “That was eagle habitat, but also our habitat.” “We stepped up.” He mentioned that this situation led a nonprofit organization, Fish and Wildlife, to launch “hugely successful” eagle protection projects.

By 2007, the bald eagle was removed from the list as the species regained its health, reaching nearly 11,000 nesting pairs nationwide, and today’s number is somewhere around 500,000.

For those looking to assist in the ongoing comeback of the bald eagle and other endangered animals, Davis said, almost every state has a center that accepts donations and welcomes visitors and volunteers.
