Yining Chen here. Every month, my family used 8 tons of water—enough to fill 15 pools—and 200 degrees of electricity. After four years of small changes, we cut those numbers in half and saved a mountain of fuel. Today I want to show you the simple switches that let kids like us rescue the planet one drop and one watt at a time. My name is Chen Yining, and my English name is Christine. I'm 10 years old.I love reading and am very good at playing the guzheng. I have a deep love for Chinese culture and hope I can tell Chinese stories in English.

A third-grader whose biggest dream is to become a firefighter gives a speech. She's training herself to be “bear-strong” enough to save people and bring smiles when they’re scared. My name is Chen Yuzhu. I'm a lovely girl. I'm going to be in Grade 2 this new term. I have many hobbies. I like drawing pictures. It's fun to use colors to show the world in my mind. I also love English. Learning English words and singing English songs make me happy. And roller - skating is really cool. I feel like I'm flying when I skate. Besides, I enjoy making friends. Friends can play together and share happy things. That's me, a girl full of energy and love for life. Thank you!

I once was a small kid in line and the biggest target in the hallway. Words felt heavier than fists, and silence echoed louder than screams. When the stats showed millions bullied each year, I stopped counting bruises and started counting voices. Today I’ll share my true story, real data, and the simple steps we can take right now to turn fear into flowers blooming on both sides. Let’s take one brave step together to protect our minds and each other. My name is Angel and I'm 15 now!

On smoggy mornings I count grey buildings instead of clouds, and that makes my heart cough louder than my lungs. So I dug into data, toured computer-controlled factories, and watched exhaust shrink by 57%. Today I’ll share how lithium-ion hearts and smart machines can turn poisoned skies into blue playgrounds for our kids. Technology isn’t just gadgets—it’s our super-tool to steady the planet and let future laughter shine brighter than factory smoke. 2024：Zhai Boyu, a student from Qingdao Hainuo Bilingual School This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

I once unwrapped lunch without a second thought, yet every plastic fork I tossed still haunts some beach today. The billions spent cleaning up and the fisheries collapsing are bills our planet can’t keep paying. But despair isn’t on the menu—scientists now serve biodegradable plastic, and I carry my own chopsticks like tiny swords. If we refuse single-use today, Earth won’t wait for tomorrow. Let’s trade convenience for conscience and save the only home we share.

When skipping rope left me aching and afraid of being laughed at, I almost quit—until I counted 800, then 1,000, then 2,000 jumps in a row. That rope taught me that the summit isn’t a place, it’s the decision to take one more jump when quitting feels easier. Today I’ll share how every small count can turn “never” into “done.” My name is Shao Ziyu. I'm 12 years old. I like reading, drawing, and doing sports.
