Here are four women who made it their life's mission to make the world a better place through environmental activism.

Greta Thunberg

"I have not accomplished anything. "This statement was made by Greta Thunberg(17 years old)and it couldn't be further from the truth. Her dedication to protecting the environment for our future generations is all accomplishment on its own. Her ability to resist to adults in power is admirable and continues to push the importance of conservation to the front of our minds.

Peggy Shelmrd

WE ACT for Environmental Justice is an organization that" through advocacy, planning, and research…mobilizes low-income communities to make environmental changes. "At the helm(掌权)of WE ACT is Peggy Shepard. Her goal is to make sure that sustainable environmental practices are accessible to all, regardless of circumstance.

Rachel Carson

American marine biologist, writer, scientist, and ecologist, Rachel Carson(1907—1964), was way ahead of her time. She wrote about conservation in the late 1930s and focused on her mission of protecting our oceans.

Julia "Butterfly" Hill

In the late 90s, Julia" Butterfly" Hill spent 738 days living in an ancient redwood, called Luna. This act brought awareness to the immense human threats to Redwood trees. Julia continues to advocate for the environment. "By standing together in unity, solidarity and love, we will heal the wounds in the earth and in each other. We can make a positive difference through our actions. "

Traveling through time

As children, we dream of growing older; when we are older, we dream of being children. We let our lives pass us by because we have yet to learn that the harder you yearn for time, the faster it passes. This is how my story begins.

In October of my freshman year, I took an accidental trip down memory lane. One day after school, I decided to take the long way home. I needed time to think. So off I went, walking through the grass. That was how I came to find a gap in the fence lining the school property. I passed through this gap and followed the treeline until I found myself in the far fields behind the neighborhood.

Suddenly, I remembered it was here through the fence between the school and the fields that I watched older kids having their high school graduation ceremony. In cap and gown (长袍), they stood in the middle of the field. They looked like they were having the most fun I had ever seen anyone have; they looked free.

Years later, I walked through that field on my way home from that same high school. The soccer nets were long gone, and the paint lines had washed away with the rain, but there it was, just as I remembered it. The old field felt like a moment trapped in time, a long-forgotten memory. Here I was, standing in between my past and my present and trying so hard to figure out just how all of those years had passed me by so quickly. The gap in the fence seemed like a distinct line between my years. A doorway between 5 and 15.

I've since given this place a name, Tempus Illud, a place between places. I try to take the long way home at least once a month now. Sometimes, when I cross that bridge, I see that younger version of myself. She is so young and so desperate to speed up time. I see her peering through the fence at those graduates in the cap and gown, and she's wishing she could be just like them. She, too, could feel so free that she might just grow wings and fly away. Now I'm preparing to wear the cap and gown in a few short months. But this time, I wish to leave time to its own devices.

The harder you yearn for time, the faster it passes you by. So I no longer yearn. The passage of time is inevitable, and you can't avoid it, but you can appreciate it. James Taylor sings, "The secret of life is enjoying the passage of time… Nobody knows how we got to the top of the hill, but since we're on our way down, we might as well enjoy the ride. "

Have you ever wondered what happens to all of the old objects launched into space, such as rockets and satellites? It's called space junk, and much of it is still out there now. According to NASA, the definition of space junk is "any man-made object in orbit (轨道) around Earth that no longer serves a useful function".

One large piece of space junk, a disused rocket, hit the dark side of the moon on March 4. The rocket's origin is not clear, but scientists know that it was massive – weighing about 3 tons. It must have left a large crater (坑), estimated 10 to 20 meters wide, on the moon's surface. It won't be visible right away, but scientists are trying to locate it. "We will find the crater, eventually, " Mark Robinson, lead investigator for NASA Lunar Reconnaissance Orbiter Camera, told USA TODAY. "Depending on its location, it could take as long as 28 days. "

What's significant about this space junk crash is that it draws attention to some of the potential dangers of space junk. First, the accumulation of space junk in Earth's orbit means that satellites and the International Space Station (ISS) are at risk. In 2016, tiny space debris (残骸), smaller than a millimeter, caused a tiny chip in the ISS' window. Imagine the damage that a larger piece of debris could cause. The European Space Agency website states that objects "up to 1 cm in size could disable an instrument or a critical flight system on a satellite" while objects over 10 cm "could shatter a satellite or spacecraft into pieces". If this sounds terrifying, that's because it is. Any collision with larger pieces of debris could be especially dangerous for manned spacecraft.

In addition to potential damage to spacecraft and satellites, space junk also poses a threat to the Earth itself. Crashes can send debris into the atmosphere where it can remain for many decades. Some powerful collisions can even send large debris hurtling (猛冲) toward Earth's surface where it can affect the local environment. Leftover rocket debris can contain toxic materials that are harmful to plant and animal life. Some people in Siberia have even reported serious health problems after rocket debris landed in their regions in 2012, a local doctor told the BBC.  

A bat and a ball cost $1. 10 in total. The bat costs $1. 00 more than the ball. How much does the ball cost?

If you answered 10 cents, you're not alone—most people give the same answer (the correct answer is 5 cents). It's an example of how we often rely on intuitive (直觉的) responses—answers we feel are true. People give answers that "pop into their mind, " says Steven Sloman. We don't spend much time "reflecting and checking whether the answer is right or wrong."

The bat and ball question helps explain why we often believe in fake news. It is part of human nature to believe, says Sloman. But "the trick with fake news is to know to verify" — in other words, to stop and question what you know. In one experiment, Sloman and a colleague invented a discovery called helium rain. They told a group of volunteers about it, but admitted they could not fully explain what it was. They then asked the volunteers to rate their own understanding of helium rain. Most volunteers rated themselves 1 out of 7, meaning they did not understand the concept.

The researchers then told another group of volunteers about the discovery. This time, they said that scientists could fully explain how it works. When asked to rate their understanding, the volunteers gave an average answer of 2. The scientists' confidence gave the volunteers an increased sense of their own understanding, Sloman says.

According to Sloman, studies show that knowledge spreads like a contagion(传染病). This idea can be seen in many fields, including politics. "If everyone around you is saying they understand why a politician is dishonest, " Sloman says, "then you're going to start thinking that you understand, too. "

Another explanation for the spread of fake news is "motivated reasoning, " writes Adam Wyatz, an American management professor, "we are naturally more likely to believe things that confirm our existing opinions. "

So in a world where misleading information is common, training people to care about fact-checking is important, especially in online communities. "We should check things and not just take them at face value," Sloman says. "Verify before you believe. "

Why Are Tigers Orange?

The colors of an animal serve lots of different purposes — for instance, to help them hide into surroundings and escape from being noticed by preys (猎物). For tigers, their ability to be invisible will just decide whether they catch dinner or go hungry.

As for humans, orange is a color used for items that need to stand out, like traffic lights and safety vests. That's because we have what's called trichromatic color vision, which differentiate three types of color: blue, green and red. But most other mammals, including dogs, horses and deer, have dichromatic (二色的) color vision for only two colors: blue and green. Humans who get information only of blue and green are considered color-blind, and can't distinguish between red and green colors.

Mammals like deer are the tiger's main prey, and their dichromatic vision means they don't see tigers as orange — they see them as green. That makes the tiger much harder to spot as it's prowling behind a bush or crouching in the grass. Although green tigers would probably be even harder to spot, evolution (进化) just doesn't work with the ingredients necessary to make green fur. The only recognizably green mammal is a sloth, and its fur isn't green in fact. That's an alga that grows in its fur.

There seems to be no evolutionary pressure, particularly for deer, which are the main prey of the tiger, to become trichromatic. That's probably because the tiger doesn't know it's orange either. So, the evolutionary race really doesn't exist for that color. It's just that the tiger has evolved over the sweep of evolution to have a coloring, a hiding system, which protects it very well in its jungle setting.

It was the first night of a tiring seven-day 250km race across the Gobi Desert a year ago. Mr. Leonard1a little dog going around his camp trying to2herself.

"Cute, but I'm not giving you any," Leonard thought. Like all3, he had packed just enough for the whole4. He'd been running competitively for three years, and he had a 5to win.

The next day, at the starting line, the dog6him again. He waved her away,7she might be stepped on by the runners.8, the dog followed him all the way until the day's race9. That night the dog snuggled (偎依) up to Leonard and even10to get a little food from him. By then, he was determined to11her Gobi.

The pair went on to finish the seven-day race, with Gobi12a distance of 125km on her own, and winning Leonard over, enough for him to make a13— he would take her home to Edinburgh. "Seeing Gobi on the race14my attitude to things. It made me think more about stopping and helping her,15just focusing on winning, " said Leonard, who finished second. "It also made my running more 16, giving me a lot of pleasure. "

As Leonard was preparing to get Gobi home, she was17. With a group of 20 local volunteers coming to his18, he finally found her. After that, Leonard never let Gobi out of his19. Now Gobi's favorite activity is still running, and she20does at least 8km a day with Leonard up the hills.

Yesterday, when I complained with my mom about too little entertainment, she share the story of her youth with me. In the 1980s, neither iPads nor smartphones were invented. Each time when evenings approached, the children around would crowd into the only house where had a television. We stared at the small screen until the program ended. Parent would make every effort to drag their children to bed when it was getting lately. But now, iPads and smartphones have taken place of televisions. No wonder my mom always says we are the generation growing up in a honey jar. After listen to my mom's story I felt lucky to live so a happy and comfortable life.
