The Araguaia River is one of the biggest rivers in Brazil. It is home to thousands of animals. River dolphins swim and play in the water, and there are many different colored fish.

In one town, a 13-year-old boy named Rhenan walks along the river every day. But looking at the river makes him worry because there is rubbish everywhere. He sees plastic bottles, old clothing, and empty food packages. The water looks dark and ugly.

One day Rhenan asked about the dirty river at school. “You wouldn’t want rubbish in your house,” said his teacher. “Think about the poor animals!” For days, Rhenan couldn’t stop thinking about the river. It doesn’t seem right to him that this big and powerful river is filled with rubbish. “It’s hurting the animals in my area,” he thought. “And it’s also hurting the families who live here.” Then Rhenan had an idea.

The next morning, Rhenan talked to his mother about his plan for the river. He wanted to go around his town and ask for everyone’s help. Maybe if they all worked together, they could clean up the river!

Rhenan’s mother loved his idea. “I believe the most important thing for you, Rhenan, is learning how to change things that you care about. That will stay with you forever.” She said. She told him she would help him along the way.

The next day, Rhenan went to the police department and next to the office of the Mayor (市长). He visited offices, businesses, and other schools. Soon he had a very big group of people who like his idea! They all decided to meet at the river the following week. On the day of the river clean-up, Rhenan was excited—but he was also nervous. What if no one showed up? But when he and his mother arrived, there were almost a hundred people there, including many of Rhenan’s friends.       

3 . Unless you’ve been faithfully bringing reusable shopping bags to the store, you probably grab the plastic bags waiting for customers at the checkout. You’re not alone.

About 100 billion plastic bags are used in the U. S. each year. Unfortunately, single-use plastic bags have serious consequences once our trip to the store is over. Less than 10% of plastic bags used in the U. S. are recycled, leaving the rest to end up in landfills (垃圾填埋场), and polluting soil, oceans and other natural habitats.

To fight pollution and other environmental problems, major companies are taking steps to get rid of the use of plastic shopping bags. If you’re a frequent customer at Walmart, don’t be surprised if you notice the plastic bags disappearing over the next few months. Last summer, Walmart announced its goal to be a zero-waste company — meaning no more plastic bags.

But Walmart has announced its Beyond the Bag, an initiative (倡议) working to explore reusable options and “reimagine” the plastic bag. Target and CVS are also on board as founding partners of Beyond the Bag, and so far, the three brands have invested $15 million to come up with a brand-new bag design.

The initiative also started the Beyond the Bag challenge, giving innovators (创新者) a chance to share their ideas. The challenge ran throughout the summer of 2020, and nine winners from over 450 submissions were selected. From a station supplying reusable bag in-store to a new and improved paper bag, the winning designs cover a lot of bases. Each product now has the chance to be tested with funding from the initiative.

While a final replacement for plastic bags at Walmart has yet to be decided, there’s a more sustainable future on the horizon. And if you want to start reducing your use of plastic bags right now, check out our list of reusable bags to bring on your next shopping trip.

5 . It took a wave of water full of plastic crashing over Babacar Thiaw as he went out to sea for him to decide to act. By the time his surfboard had carried him back to Virage beach on the north shore (岸) of Senegal’s capital, Dakar, Thiaw had a plan to make use of the surfing community he had built there.

Within a year he had turned Copacabana Surf Village, which he founded with his father two decades ago, into a center for young Senegalese eco-surfers, where he organizes beach cleans, environmental courses for children and runs Senegal’s first zero-waste restaurant.

Thiaw grew up in a fishing village near the beach, and the Copacabana Surf Village’s foundations (地基) were laid by his fisher father, who after a day’s work would head to Virage beach to surf on a wooden board. They worked hard to turn the Village into a business by renting out surfboards and later offering lessons with the help of visiting overseas surfers.

It is now a popular surfing location, attracting tourists. It’s also a place where Thiaw teaches young Senegalese how to surf and care for the ocean they spend so much time in.

“When we come to the water to surf, we can see how much plastic is ending up here and it disturbs (使烦恼) us,” says Mohammed Sarr, 17, who Thiaw taught to surf. Sarr says he has become more aware of how he uses and deals with plastic because he and his family, who live near the sea, are directly affected.

Thiaw says there was doubt about the plastic-free initiative (倡议), with diners questioning whether it was healthy for him to be serving water in reusable glass bottles. But he stresses that everyone needs to understand the requirement to change .“ Once the environment is getting worse, you and your family and friends will surely suffer,” he says.
