How can kids become heroes? Do they have to save the world? No. To become a hero, kids just have to think about what others need and find a way to help. Katie Stagliano is one of those hero kids.

Katie loved to garden. When she was 9, she harvested a huge cabbage which weighed 40 pounds. The cabbage was far bigger than what her family needed, so she thought about what to do with it.

She knew that there were lots of hungry people in South California, where she lived. So she decided to donate her enormous cabbage to a soup kitchen. It turned out that her kind donation helped feed more than 275 people.

Then Katie thought about other gardeners who had more vegetables than they could eat.

Suddenly, she saw a way to solve both problems. Katie realized that she could help fight against hunger by encouraging kids to plant vegetable gardens and donate their harvest to hungry people. That's how Katie's Krops was born.

Katie says, "My dream is that there are no hungry people." To make that dream come true, Katie got her whole school involved. The students planted a huge garden, but Katie knew she could do more. She contacted an organization called Fields to Families, which sent a master gardener to help.

It's so great to help people," Katie adds, but kids don't have to grow huge cabbages. If they could grow "even one vegetable plant and donate the harvest to a local soup kitchen, we could make a huge difference in the fight against hunger".

It's been several years since Katie Stagliano started work on her dream. Today, more than 60 gardens around the United States are being grown by kids. Young gardeners have donated tens of thousands of pounds of fresh vegetables to stop hunger.

Sadly, many people are still hungry. However, Katie's Krops and hundreds of child gardeners are planting and harvesting to change that.

Alex Elman runs a big business — something hard to imagine after she lost her sight in her twenties. But Elman says that losing her sight helped her focus on finding success.

Elman’s father planted a hillside vineyard (葡萄园) in western Massachusetts in 1981. It’s where Elman fled during the darkest period of her life. When she was 27 years old, she went blind due to complications from juvenile diabetes (青少年糖尿病) 17 years ago. She recalled, “I hid in my home. I hid in the place, to me, that was the safest place in the world.”

Elman is now the founder of Alex Elman Wines, a growing collection of organic wines from all around the world: Chianti from Italy, Torrontes from Argentina. Elman doesn’t work alone. Her assistant, a guide dog named Hanley, is something of a wine taster, and quite a beggar. Hanley travels to all of the wineries that Elman does, from South America to Europe.

At first, Elman resisted the idea of a seeing-eye dog. Now it’s hard to imagine her life, or her business, without him. She said, “When someone tells me something is organic and I don’t really believe it because I taste something funny on it, I’ll put it in front of his face and if he likes the wine, he’ll actually go in and sniff it. If it’s not right, he’ll turn his head away ... He gets in the dirt with me. He scratches around. He makes sure that we see earthworms and butterflies. That’s how we know that the soil is actually organic, that there are no chemicals.”

Elman told CBS News she believes the loss of her vision was a gift. She said, “It allowed me to pay attention to what I thought was important and also to be able to teach people that the broken hang nail is not a big deal, you know what I mean? Don’t sweat the small stuff. Don’t sweat the big stuff either.”
