Now, Earth Day is celebrated around the world. We still face many challenges, such as climate change, plastic pollution, and deforestation. But we can all make a difference.

Her Trees Save Lives

Adeline Tiffanie Suwana was 12 when her family's home flooded. Indonesia, her island nation, is often hit hard by floods and other natural disasters.

Adeline learned that mangrove trees play a key role in flood protection and rallied classmates to plant 200 trees during a school break. They started a group called Sahabat Alam or Friends of Nature, which works to conserve the region's biodiversity and combat climate change.

Today. Adeline attends university, studying how businesses can help the environment.

Teens' Two-Fold Invention

EPS—expanded polystyrene foam—is the white, lightweight stuff used to make things like takeout food containers, foam egg cartons, and packing "peanuts". But it takes up a lot of space and is difficult to recycle. EPS breaks into small pieces as it floats down waterways into oceans, harming wildlife along the way.

Eighth-graders Julia Bray, Luke Clay, and Ashton Cofer looked at EPS's chemical makeup and saw that it was mostly carbon. That sparked an idea. Could they turn it into activated carbon, a material that filters toxins from water?

After 50 hours of experiments, including one that accidentally set the family grill fire, they succeeded!

Solar for Her School

When Claire Vlases of Montana was in seventh grade, she learned about plans to expand and modernize her middle school. Claire asked the school board to add solar panels to the project. The board liked the idea but said it could contribute just $25,000, one-fifth of the cost. So Claire organized a group of kids and adults who set to work raising the rest.

They asked for donations, even going door-to-door for them. And they appealed to charitable foundations too. One even donated half the cost!

After two years of hard work, the group paid for the solar panels, which now supply one-fourth of the school's electricity needs.

New year was just around the corner. I was second grade then, 7 years old. One day, on my way home from school, a lady gave me a piece of paper (say) that the neighborhood was asking people to give New Year presents to those needed them. When I showed my mom this paper, she encouraged me to take part in it and spread (kind) to others less fortunate than us. She said we would become "Neighborhood Angels"

Several days later, my mother (drive) me to the store and gave me $20 to pay for neighborhood present. Then she said, "I'll see you outside in the car." She left me alone to do the shopping I was not used to (buy) things on my own, as I had always been with one of my (parent) before. Everything seemed very strange and confusing to me, I carried on. Suddenly, the poor boy (call) back who lived in our neighborhood. I used to see him jacket during the freezing winter months, so I decided, then and there, to buy him a warm jacket. I looked at many jackets and (final) chose a heavy blue one. That evening, I sent the present to him with my mom. Seeing the tears in his eyes, I felt as if l were a real "Neighborhood angel"

This happened when I was ten. On a normal Sunday, I went to the barber shop where I always went. That day, along with the barber there was an assistant, who had recently1 the shop.

So I sat for the haircut. The uncle asked me how2 I wanted it. I answered, "Just do as my dad had3 you the last time."

He smiled. Before starting the4 , he added, "What if I keep it long?"

I 5 he was joking. So I joked too. I said, "can't 6 what would happen to your shop then!"

The moment I said it, the assistant7 from behind."How dare do you say that! Who are you to take us down, eh?"

I admit I was too8  at that moment and the uncle standing beside me was giving me an9 look.

From that day on, I10 stopped joking about anyone's profession and works. It is one of the most11 in my life, which taught me to12 the profession and works of a person, no matter how13 they are.

I'm14 that the assistant responded in a way that made me rethink the power of my words. Words do make a 15 .

How to Avoid Leg Pain when running

While Running is fantastic exercise, it's also a relatively high-impact activity. Pounding on the pavement can cause Leg Pain. 

Spend longer warming up If you commonly have leg pain when running, your muscles may not be sufficiently warm.  Then include dynamic stretching in your warm up routine after a brief walk. These types of stretching can better loosen your leg muscles and prepare them for a run, which may help you avoid leg pain.

Evaluate your form. Get a coach or experienced runner to observe you running and give you tips on what might be causing your leg pain. For example, if you're leaning too far forward when you run, you can pull too hard on your calves(小腿肚). This can result in the pain of the lower legs

If you're getting cramps(筋) or other leg pain while running, it may be because you need to build up your cardiovascular (心血管) fitness more gradually. Start by walking or jogging at a slower pace, and slowly work up to faster speeds.

Use relaxation techniques while running. Deep breathing and other relaxation techniques give you better mental focus. which can keep you from developing leg pain. You can find recordings online or on your favorite music app. These recordings can help you focus on your breath and reach a more relaxed state as you run.

A. Slow your pace

B. Shorten your step.

C. Here are some skills to avoid leg pain.

D. They also reduce the overall stress in your body.

E. A shorter walk with long steps allows you to avoid leg pain.

F. Take a few more minutes to walk before breaking into a run.

G. If you frequently have leg pain while running, poor running form is to blame
